are discussed. Procedures such as annealing, quenching, and tempering are outlined in depth. Bibliography lists 4 sources. SA146het.rtf The beginnings
of metallurgical science may be traced to about 3500 BC where in Egypt, Mesopotamia, China, and India, the art of smelting metals from ores had been discovered ("Metallurgy," 1998).
It began with the natural alloy bronze, but later, gold, silver, tin, lead, and copper had been worked in various ways, even thought they had been previously cold-hammered as
native metals for thousands of years (1998). The smelting of iron had been discovered at around 1500 BC (1998). The Romans were first to harden and temper iron into steel,
with the use of heat treatment (1998). Fast forward to the nineteenth century, and advances were made. The invention of the Bessemer process in 1856 had made cheap steel
a reality (1998). Heat treating is a large topic and heat treatments utilized often depends upon the metal involved, and intended use ("Heat,"
2001). The goal of the heat treater is generally to create a balance between good metallurgical properties with dimensional control during the heat treating process (Tarney, 1998).
There are of four general steps in the process and these are preheating, austenitizing, quenching, and tempering, and each part of the process does have an effect on the final
properties of the tool (1998). Iron will organize itself into an atomic structure at common temperatures and the result is what is called
a body-centered cubic ("Heat," 2001, p.PG). It consists of overlapping cubes along with an atom at each corner, in addition to one more in the center of a cube
