Heat Treating Overview Heat treating, as the name implies, is a series of treatments in which heat is used to alter the properties of a metal or alloy. Heat Treatment •process of controlled heating and cooling of metals •Alter their physical and mechanical properties •without changing the product shape •sometimes takes place inadvertently due to manufacturing processes that either heat or cool the metal such as welding or forming. For example, fracture toughness and the crack growth rate can be controlled by performing an adapted heat treatment process prior to solution annealing. Many heat treating processes require the precise control of temperature over the heating cycle. Download now. METAL CLASSIFICATION All metals may be classified as ferrous or nonferrous. Records Heat treatment practices used by steel foundries have been carefully studied as part of comprehensive heat treatment procedure qualification development trials.

Annealing, Normalizing, Quench Hardening, Tempering, and Austempering are five of the important heat treatments 3 0 obj Standard: Page 1 of 1 Doc. HEAT TREATMENT OF STEEL Purpose The purposes of this experiment are to: Investigate the processes of heat treating of steel Study hardness testing and its limits Examine microstructures of steel in relation to hardness Background To understand heat treatment of steels requires an ability to understand the Fe-C phase diagram shown in Figure 6-1. A Classical Heat Treatment Classical Heat Treatment is the process of controlled heating and cooling of metals in order to obtain the desired mechanical, chemical and metallurgical properties during the manufacturing of a product. The book contains chapters that discuss the fundamentals of TTT-diagrams and hardening mechanisms, injection metallurgy and continuous casting, annealing processes, strain aging and temper brittleness. CERTIFIED TEST REPORT - HEAT TREATMENT (FORM 460 CLAUSE 101) (If an equivalent form is used it must contain all required information.)
