我们用下列成分的钢研究了残留奥氏体的含量随回火温度变化的情况。C-1.04%、Mn-0.37%、P-0.008%、S-0.011%、Si-0.26%、Cr-1.48%、Ni-0.10%、Mo-0.04%用 AVERBACH 和 COHEN 的射线结晶法测定残留奥氏体的含量。众所周知,残留奥氏体的存在明显地影响钢的性能。此外,这种相是不稳定的,在使用过程中可能发生转变而改变钢的结构状态。因此,研究这种 We used the following composition of steel to study the residual austenite content with the tempering temperature changes. C-1.04%, Mn-0.37%, P-0.008%, S-0.011%, Si-0.26%, Cr-1.48%, Ni-0.10%, Mo-0.04% The content of the body. It is well known that the presence of retained austenite significantly affects the properties of steel. In addition, this phase is unstable and may change during use to change the structural state of the steel. So, study this
