Isothermal Transformation Within the Medium Temperature Range in a β'Cu-Zn Alloy

β′Cu-Zn合金中温区等温转变的研究

According to austenite isothermal transformation diagram, a heat treatment process for producing the left and right pincers through fixed heating time and the position was put forward.

借助奥氏体等温转变曲线，创立了定时定位的热处理工艺方法，用于左右钳口的生产，一次达到设计要求，简便可靠，省时节能。

At the same time the transformation points, Ac1, Accm and Ms were measured using thermal dilatometer and differential scanning calorimeter. Then different isothermal transformation treatments of the steels were carried out.

同时利用膨胀法和差示扫描量热法测定了两种钢的相变点Ac1、Accm和Ms。然后对试样进行了不同工艺的低温等温转变处理。

From this point, the Medium Temperature Transformation is studied for a low-carbon alloy structural steel cooperating with observation of its microstructures, to draw the kinetic curves of Isothermal Transformation at some temperature and TTT-diagram of Medium Temperature Transformation of the steel.

从这点出发，配合显微组织观察，对一种低碳合金结构钢的中温转变进行了研究，作出了这种钢的一些温度下的等温转变动力学曲线以及该钢的中温转变的TTT图。
