摘要
为了提高６５Ｍｎ飞锯片的切削寿命，对６５Ｍｎ飞锯片进行了等温处理和淬火＋回火处理两种热处理工艺试验，对两种热处理工艺后的６５Ｍｎ飞锯片的硬度、韧性，抗弯性能和耐磨性能进行了测试对比，并经过生产试验，指出等温处理明显提高了６５Ｍｎ飞锯片的切削寿命。
In order to increase the cutting service life of 65 Mn fly-saws, two kinds of heat treatment are handled. The hardness, toughness, bending property and abradability of these kinds of 65 Mn fly- saws are tested and compared. The experiments show that isothermal treatment can increase 65 Mn fly-saw cutting service life greatly.
