摘　　要：通过对铍材料的刻划实验,在切入深度3μm以内观察到了铍材料的塑性流动与挤压。在此过程中,法向刻划力F z的变化符合脆塑转变规律;通过对微细铣削切削力的检测、加工表面的形貌特征表征,证实了铍材料塑性域加工的可行性,为进一步的工程应用奠定了理论基础。The plastic flow and extrusion of beryllium is observed in scratch experiment by the cutting depth of 3μm.The evolution process of vertical scratch force F z is consistent with brittle-ductile transition.The possibility of ductile regime machining for the beryllium is approved by micro-cutting force and surface quality test,which lay the theoretical theory for the engineering application.
