Iggy, on the other hand, played her hand like the pharaoh of Exodus, hardening to criticism after every dig, flipping first on Azealia Banks, then rap legend Q-Tip, and ultimately, her own mentor and hood pass adminisrator T.I. instead of working to grasp what is so infuriating to people of color about her stardom.

"Signing of the executive order will add yet another complication to the current trade tensions with Beijing and be used by those in Beijing's leadership warning against signing a deal with the U.S.," former CIA head of China analysis Dennis Wilder told FT,"because the attitudes of the Trump administration toward China are hardening to a point where a viable trade deal may not be possible."[Reuters]

Much gold jewelry is produced by casting, with little or no cold working; which, depending on the alloy grade, may leave the metal relatively soft and bendable. However, a Jeweler may intentionally use work hardening to strengthen wearable objects that are exposed to stress, such as rings.

Ice and snow cover also helps keeping the temperature stable. Freezing tolerance is enhanced by cold hardening. To adapt to the cold temperatures, B. antarctica accumulates trehalose, glucose, and erythritol. These compounds help the insect survive freezing by reducing the amount of ice that forms within the body.

Boriding gives the material the following desirable properties: wear resistance, improved hardness (1300-2000HV is possible), thermal stability, resistance to corrosion by acids, reduced coefficient of friction, and increased galling/cold-welding resistance. It is possible to combine boriding with other heat treatments such as carburizing, hardening or induction hardening to create deeper wear layers or high core hardness.

Although providing corrosion resistance, the colored surface layers are subject to wear and may also fade with time. Antique firearms for sale frequently note the specific percentage of the factory original case coloring remaining on the receiver and lockplates. Renewing this color case hardening to the specific patterns of the firearm when it was new has become an important sub-area of the gunsmithing field.

Cold hardening has also been observed in insects such as the fruit fly and diamondback moth. The insects use rapid cold hardening to protect against cold shock during overwintering periods. Overwintering insects stay awake and active through the winter while non- overwintering insects migrate or die. Rapid cold hardening can be experienced during short periods of undesirable temperatures, such as cold shock in environment temperature, as well as the common cold months.

Tetradymia comosa is a whitish woolly shrub growing to over tall. The leaves are lance-shaped and up to 6 centimeters long, becoming rigid as they age, sometimes with their tips hardening to spines. The inflorescence bears three to six flower heads which are each enveloped in five or six thick phyllaries coated in white woolly hairs. Each head contains five to nine yellow or brownish flowers each around a centimeter long.

Compact controllers in high-end equipment are available with touchscreen and graphical representation of the control loop or the system. In addition to the actual control loop, compact controllers can also take over control tasks and thus control the process sequence or parts thereof independently. Compact controllers can be found in almost all industries. For example, the program controller function is often used in the food industry, or in hardening to define specific temperature profiles.

The central "crater" of the map is a signature of bond hardening. To appreciate the uniqueness of this signature requires explaining other features on the map. The horizontal axis of the map gives the time-of-flight (TOF) of ions produced in ionization and fragmentation of molecular hydrogen exposed to intense laser pulses. The left panel reveals several proton peaks; the right panel shows relatively uninteresting, single peak of molecular hydrogen ion.

Shot and shell used prior to and during World War I were generally cast from special chromium (stainless) steel that was melted in pots. They were forged into shape afterward and then thoroughly annealed, the core bored at the rear and the exterior turned up in a lathe. The projectiles were finished in a similar manner to others described above. The final, or tempering treatment, which gave the required hardness/toughness profile (differential hardening) to the projectile body, was a closely guarded secret.

This ability can be used in hardening to produce parts with varying properties. The most common hardening process is to produce a localised surface hardening of an area that needs wear-resistance, while retaining the toughness of the original structure as needed elsewhere. The depth of induction hardened patterns can be controlled through choice of induction-frequency, power-density and interaction time. Limits to the flexibility of the process arise from the need to produce dedicated inductors for many applications.

They acted as steering devices for the projectile, using a minute-vibrating diaphragm-like system powered by piezoceramic elements. Due to the tiny air vortices created by the synthetic jets, an asymmetry in the airflow could be created around the projectile. In addition, the resulting Coanda effect multiplied this effects of this phenomenon, producing air flow changes that were strong enough to change the projectile's trajectory. The SCORPION's electronics have also undergone g-hardening to withstand the heavy forces generated during each launch.

The three warheads were stated to be equivalent in destructive power to a single one-megaton warhead due to their spread out pattern on the target. The first Polaris submarine outfitted with MRV A-3's was the USS Daniel Webster in 1964. Later the Polaris A-3 missiles (but not the ReBs) were also given limited hardening to protect the missile electronics against nuclear electromagnetic pulse effects while in the boost phase. This was known as the A-3T ("Topsy") and was the final production model.

When the existence of bond softening was experimentally verified in 1990, the attention turned to bond hardening. Rather noisy photoelectron spectra reported in the early 1990s implied bond hardening occurring at the 1-photon and 3-photon anticrossings. These reports were received with great interest because bond hardening could explain apparent stabilization of the molecular bond in strong laser fields accompanied by a collective ejection of several electrons. However, instead of more convincing evidence, new negative results relegated bond hardening to a remote theoretical possibility.

In 1900 he succeeded pathologist Felix Victor Birch-Hirschfeld (1842-1899) at the University of Leipzig. In 1904 Marchand is credited with coining the term atherosclerosis from the Greek "athero", meaning gruel, and "sclerosis", meaning hardening, to describe the fatty substance inside a hardened artery. His name is lent to the eponymous "Marchand's adrenals", which is accessory adrenal tissue in the broad ligament of the uterus. Among his written works was a 4-volume textbook on pathology that he co-authored with Ludolf von Krehl (1861-1937), called "Handbuch der allgemeinen Pathologie".

Applies various chemical processes (browning, bluing, Parkerization, among others) to the metal parts of guns to develop corrosion resistant surface layers on the steel. They may also apply case hardening to low carbon steel parts. Case hardening is a combined chemical and heat-treatment process which introduces carbon into the surfaces of low steel alloys that does not contain sufficient carbon to allow total ("through") heat treatment. This carbon rich surface is then heat treated resulting in a thin, very hard surface layer with a tough, malleable core.

New Edge of the Anvil: a resource book for the blacksmith. pp. 98–99 Tempering is a process of heat treating, which is used to increase the toughness of iron-based alloys. Tempering is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air. The exact temperature determines the amount of hardness removed, and depends on both the specific composition of the alloy and on the desired properties in the finished product.

This carburizing package is then heated to a high temperature but still under the melting point of the iron and left at that temperature for a length of time. The longer the package is held at the high temperature, the deeper the carbon will diffuse into the surface. Different depths of hardening are desirable for different purposes: sharp tools need deep hardening to allow grinding and resharpening without exposing the soft core, while machine parts like gears might need only shallow hardening for increased wear resistance. The resulting case-hardened part may show distinct surface discoloration, if the carbon material is mixed organic matter as described above.

The archaeological record in Egypt, Peru and the Caucasus suggests that arsenical bronze was produced for a time alongside tin bronze. At Tepe Yahya its use continued into the Iron Age for the manufacture of trinkets and decorative objects, thus demonstrating that there was not a simple succession of alloys over time, with superior new alloys replacing older ones. There are few real advantages metallurgically for the superiority of tin bronze, and early authors suggested that arsenical bronze was phased out due to its health effects. It is more likely that it was phased out in general use because alloying with tin gave castings which had similar strength to arsenical bronze but did not require further work- hardening to achieve useful strength.

Evans Bros, 1965, . p. 95 This aspect of Hannibal's leadership was highlighted in the use of a Spanish unit, the Balearic slingers, whom he placed behind the infantry to hurl their ranged missiles into the masses of Roman troops. He placed his Iberians, Celtiberians and Gauls in the middle, alternating the ethnic composition between Spaniards and Gauls across the front line, with himself at the front and center alongside his brother Mago. Roman sources claim their placement was chosen for being the most expendable and unreliable troops, but modern reflections believe those forces were actually selected for their battle-hardening to carry the weight of the Punic side, as they were tasked with the controlled retreat that ultimately made possible Hannibal's pincer movement.
