铣削表面残余应力试验

镍基高温合金GH4169具备优异的高温强度和硬度，良好的抗疲劳性能和断裂初性、以及良好的抗氧化性和抗热腐蚀性，被广泛用于制造航空发动机中的涡轮叶片等热端部件。但是该合金切削加工时塑性变形大，导热系数较低，在进行切削加工时的切削力大、切削温度高、刀具磨破损严重，刀具寿命短，属于典型难加工材料。

Nickel-based superalloy GH4169 features excellent high-temperature strength and hardness, favorable fatigue resistance and fracture toughness, as well as good oxidation resistance and hot corrosion resistance, and is widely used in manufacturing hot-end components such as turbine blades in aero-engines. However, this alloy undergoes large plastic deformation during cutting, has low thermal conductivity, and exhibits high cutting force, elevated cutting temperature, severe tool wear and breakage, and short tool service life during machining, making it a typical difficult-to-machine material.
