探讨了淬火工艺对双金属带锯条齿部和背部材料的微观组织与力学性能、实际锯切寿命及断口形貌特征的影响．结果表明：淬火工艺对双金属带锯条背部与齿部材料的组织与力学性能有影响，尤其对背部材料的影响较明显．降低淬火冷却速率，使背部材料塑性以及抗疲劳性能有一定的下降，这主要是由于淬火后孪晶马氏体（含板条内微孪晶马氏体）量有所增加，回火后，使孪晶马氏体发生退化产生脆性片状碳化物，进一步增加了回火脆性
The effects of quenching process on the microstructure and mechanical properties, the actual sawing life and the fracture surface features of the bimetal band saw blade teeth were studied. The results show that the quenching process has an effect on the microstructure and mechanical properties of the back and toothed parts of the bimetal band saw blade, especially the back material. Decreasing the cooling rate of quenching, the back of the plastic material as well as the fatigue resistance of a certain decline, mainly due to the quenching after twins martensite (including twins within the micro-twin martensite) increased the amount of tempering, Degeneration of twin martensite produces brittle flake carbides, further increasing the temper brittleness
