利用自装的专用样品夹具台和平行光束X射线应力测定仪上的常规法测量机构,对三种奥氏体型铁基高温合金的模拟拉削表面进行了有倾角侧倾法测量。测量结果表明,拉削进刀方向与退刀方向上的2θ-sin~2ψ关系都严重偏离直线,而且它们的2θ-sin~2ψ曲线明显相互分离。文中对导致产生这种异常的2θ-sin~2ψ关系的物理原因进行了探讨。 The tilted roll method was used to measure the simulated broaching surfaces of three types of austenitic iron-based superalloy using a conventional measuring mechanism on a self-contained dedicated sample holder and a parallel beam X-ray stress meter. The measurement results show that the relationship between 2θ-sin and 2ψ in the direction of broaching and retracting is seriously deviated from the straight line, and their 2θ-sin ~ 2ψ curves are obviously separated from each other. In this paper, the physical causes of the relationship between 2θ-sin and 2ψ which lead to this anomaly are discussed.
