【摘要】 ZGMn13钢水韧处理加热过程中不同等温温度将产生不同的显微组织，根据这个原理，分析了容易产生裂纹的等温温区，并推荐了最佳等温温度。更多还原

【Abstract】 The different isothemal temperature of ZGMn13 steel during the water toughening process will pro-duce different microstructures. Based on this principle,we have analized the isothermal temperature range in which thecracks are apt to arise. And then the optimum isothermal temperatures are recommended.更多还原
