0　引言目前热处理工艺并没有如人们想象的那样普遍地得到控制 ,而热处理工艺的高可靠性是非常有用的。热处理过程中一些重要参数有 :炉膛温度、工件温度、气氛的碳势、碳流量或氮流量、气流、炉压、油淬温度、淬火油搅拌和淬火激烈程度。如表 1所示 ,其中许多参数可以用有效的 0 Introduction At present the heat treatment process is not generally as controlled as people imagine, and the high reliability of the heat treatment process is very useful. Some important parameters in the heat treatment process include: furnace temperature, workpiece temperature, carbon potential in the atmosphere, carbon flow or nitrogen flow, gas flow, furnace pressure, oil quenching temperature, quenching oil mixing and quenching severity. As shown in Table 1, many of these parameters can be used effectively
