ASTM-E18 Standard Test Methods for Rockwell Hardness of Metallic Materials ASTM-A240 Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications AMS-2770 Heat Treatment of Wrought Aluminum Alloy Parts The process of heat treatment is carried out to change the grain size, to modify the structure of the material and to relive the stresses set up the material after hot or cold working. The chemical makeup of a part is one of the most critical determinants of how it is heat treated. Objectives of Heat Treatment Processes  To increase strength, hardness and wear resistance (bulk hardening, surface hardening)  To increase ductility and softness (Tempering, Recrystallization Annealing)  To increase toughness (Tempering, Recrystallization annealing)  To obtain fine grain size (Recrystallization annealing, Full annealing, Normalizing)  To remove internal stresses induced by differential deformation by cold working, non-uniform cooling from high temperature during casting and welding (Stress relief annealing)  To improve machinability (Full annealing and Normalizing)  To improve cutting properties of tool steels (Hardening and Tempering)  To improve surface properties (surface hardening, high temperature resistance precipitation hardening, surface treatment)  To improve electrical properties (Recrystallization, Tempering, Age hardening)  To improve magnetic properties (Hardening, Phase transformation), All content in this area was uploaded by Qussay Y. Hamid on Jan 06, 2020, precipitation hardening, surface treatment). Regardless of heat treat furnace type, or processing cycle, it may be necessary for users to know the temperature uniformity in the furnace and whether the material is processed in a zone within the furnace that is capable of meeting the applicable permissible temperature variation requirements. The variability in temperatures within a heat treatment furnace is one such variable that … suppliers, and heat-treaters have developed a series of specifications. ResearchGate has not been able to resolve any citations for this publication. By a proper post-weld heat treatment, the joint inhomogeneity can be effectively ameliorated due to carbide reprecipitation and stress relief in the joint. The tempering at 300 oC causes the cementite carbides precipitation which is responsible for 30% decrease in impact toughness relatively Q-P treatment. So let us learn more about what is heat treatment and what are the types of heat treatment in this article. 2 Arrangement of atoms in the two crystalline structures of pure iron.
