作者通过在生产条件下进行的试验,研究了加热温度对4Cr14Ni14W2Mo钢形成粗晶的影响,绘制了该钢种的第二类再结晶图;所得结果对制定合理的热锻工艺规范具有一定的指导意义。文中所涉及的关于再结晶图的制作方法,对从事锻压工作的同志也具有参考价值。
The authors studied the effect of heating temperature on the formation of coarse grains in 4Cr14Ni14W2Mo steel and the second recrystallization patterns of the steel grades through the tests carried out under the production conditions. The results obtained have certain guidance for the development of a reasonable hot-forging process specification significance. The article involved in the production of recrystallization map, engaged in forging work of comrades also has reference value.
