随着金属材料与热处理技术的发展,热处理的领域在不断地扩大。在热处理手段上,真空、超声、磁场、电脉冲、离子冲击、电子束、激光等正在加以利用。在金属热处理温度方面,超越原来的临界点以上30～50℃的温度范围,出现了高温控制轧制、高温形变热处理;以及处于临界点以下氮化、渗硫……等热处理。在热处理方法上,正在打破传统的工艺,出现了低碳钢淬火烧火燎、临界区淬火、超高温淬火等。在组织利用上,由
With the development of metal materials and heat treatment technology, the field of heat treatment is constantly expanding. In the heat treatment means, vacuum, ultrasonic, magnetic field, electric pulse, ion impact, electron beam, laser, etc. are being utilized. In the metal heat treatment temperature, beyond the original critical point above the temperature range of 30 ~ 50 ℃, appeared high temperature controlled rolling, high temperature deformation heat treatment; and in the critical point below nitriding, sulfur infiltration ... ... and other heat treatment. In the heat treatment methods, is breaking the traditional process, there has been quenched and torched low-carbon steel, the critical zone quenching, ultra-high temperature quenching. In the organization, by
