Heat treating

Second album by rock and roll singer-songwriter near-legend Graham Parker. A close follow-up to the debut album, Howlin' Wind, Heat Treatment was well received by critics and contains signature Parker songs like the rollicking title track, "Pourin' It All Out", and "Fool's Gold". "That's What They All Say" is a Dylan-esque putdown from a realist perspective, while "Turned Up Too Late" was perhaps Parker's most emotionally mature composition to date. "Black Honey" is a dark, downcast sequel to the debut's upbeat first track "White Honey". "Hotel Chambermaid" was covered many years later by Rod Stewart.

Heat treatment is a method used to alter the physical, and sometimes chemical, properties of a material. The most common application is metallurgical. Heat treatments are also used in the manufacture of many other materials, such as glass. Heat treatment involves the use of heating or chilling, normally to extreme temperatures, to achieve a desired result such as hardening or softening of a material. Heat treatment techniques include annealing, case hardening, precipitation strengthening, tempering and quenching. It is noteworthy that while the term heat treatment applies only to processes where the heating and cooling are done for the specific purpose of altering properties intentionally, heating and cooling often occur as incidental phases of other manufacturing processes such as hot forming or welding.

The processes through which armour is hardened through heating. In general, most iron or ferrous armour is hardened either through work hardening (done by hammering ) or by heating it to its critical temperature (dependent upon the technique used) and then quenched in water, urine, oil or other more secret substances. Prior to the 14th century, most hardened pieces were worked, planished , from the hammer rather than heat treated. During the 15th century, there is some evidence that the German armourers, particularly in Augsburg, began to use a sophisticated two step method that achieved a superior hardness and a resiliance to brittleness .
