高温形变热处理是一种将金属的高温塑性变形和热处理有机地结合在一起的复合强化工艺。它在提高钢的强度,尤其在提高钢的断裂韧性方面有独特作用。这种工艺不仅能显著提高各种钢制零件的疲劳寿命,而且还能节约能源、简化工序、提高生产率,因此引起了有关方面的普遍重视。一、高温形变热处理的过程模锻件的锻造余热淬火(下称锻热淬火)和型钢的热轧余热淬火(下称轧热淬火)都是高温形变热处理的典型工艺。它们的主要过程是:1.在钢的奥氏体化温度下进行一定的热
High temperature deformation heat treatment is a kind of metal high temperature plastic deformation and heat treatment organically combined with the composite strengthening process. It is in enhancing the strength of steel, especially in enhancing the fracture toughness of steel has a unique role. This process can not only significantly improve the fatigue life of a variety of steel parts, but also save energy, simplify processes and increase productivity, it has attracted widespread attention. First, the process of high temperature deformation heat treatment Forging forging residual heat quenching (hereinafter referred to as forging quenching) and hot-rolled steel residual heat quenching (hereinafter referred to as hot-quenching) are high temperature heat treatment of the typical deformation process. Their main processes are: 1. Perform some heat at the austenitizing temperature of the steel
