摘 要: 通过对不同锻造和热处理工艺方案得到的d100 mm TC18钛合金棒材组织和探伤结果进行研究,找出不同工艺方案得到的显微组织所对应探伤水平的变化规律。结果表明:不同工艺方案得到的典型组织,对应探伤结果存在较大差异;特别是在组织类型均为α+β两相区加工组织的情况下,随着显微组织形貌和大小的变化,探伤杂波水平发生明显变化。

Abstract:By studying the microstructures and inspection results of d100 mm TC18 titanium alloy bar produced by different forging and heat treatment process, the variation rule of ultrasonic level corresponding to microstructures obtained by different process scheme was found. The results show that the typical microstructures obtained by different process schemes have a great effect on inspection results. Especially the microstructure type is two phase α+β region processing structure. With the variation of the microstructure morphologies and size, the ultrasonic clutter level is changed significantly.
