摘要
本文对直径小于16mm的高温合金小直径棒材的检测方法进行了深入探讨,对爬波法和双晶轴向线聚焦法的探测结果进行了比较,指出双晶轴向线聚焦法是检测小直径棒材的有效方法。
In this paper,Ultrasonic testing methods are discusseed for high temperature alloy bars with diameter smaller that 16 mm,The testing results are compared which indicate that the axial line focussed double probe testing method is more effective for small bars.
