Heat Treatment of Steel (钢的热处理)Heat treatment is a method by which the heat treater can change the physical properties of a metal. There are three main operations in the heat treatment of steel: hardening, tempering, and annealing.The hardening operation consists of heating the steel above...
Therefore, the main factors acting in heat treatment are temperature and time, so that any process of heat treatment can be represented in temperature-time ( t-r ) coordinates.因此，热处理的主要因素是温度和时间，所以任何热处理⼯艺都以⽤温度-时间为坐标轴进⾏表⽰。热处理⼯艺主要有以下...
The present invention relates to improvements in processes for treatment of steel under a controlled atmosphere. Use is made of an atmosphere formed by a carrier gas comprising or containing industrially pure nitrogen and by an active gas formed by a hydrocarbon such as: CH4, C4H10, C3H8, C2H4...

This article introduces the new process(quenching and partitioning process) for steel heat treatment developed by J. 本文介绍Speer等近年来发展的钢热处理新工艺—淬火和分配(Q&P)处理,即含Si或A l的Q-P钢经淬火至Ms-Mf间一定的温度(QT)后,再在一定温度(PT,在淬火温度或者高于Ms)停留,使碳由马氏体...
Heat Treatment of Steel We can alter the characteristics of steel in various ways. In the first place, steel which contains very little carbon will be milder than steel which contains a higher percentage of carbon, up to the limit of about 1.5%. Secondly, we can heat the steel above a ...
Annealing, normalizing, quenching, tempering, and surface hardening are popular heat treatment processes. For each heat treatment process to achieve the desired properties, distinct heating and cooling rates, holding times, and temperature ranges are needed. Heat treatment of steel is indispensable in ...
