针对新型蒸汽发生器(SG)使用的钛合金材料,提出在制造时利用声发射技术对其材料性能进行监测,并通过试验对SG声发射监测的可行性进行研究。利用声发射对标准拉伸试样的拉伸试验全过程进行监测,分析获取的数据,得到钛合金材料的声发射特征以及声发射监测的灵敏度。进一步对SG拉伸试样的拉伸试验声发射监测结果,验证标准拉伸试样的分析结果,确认对该种新型SG进行声发射监测是可行的。
Aiming at the titanium alloy material used in the new steam generator (SG), it is proposed to monitor its material performance by using acoustic emission technology and to study the feasibility of SG acoustic emission monitoring through experiments. The whole process of tensile test of standard tensile specimen was monitored by acoustic emission. The acquired data were analyzed to obtain the characteristics of acoustic emission of titanium alloy and the sensitivity of acoustic emission monitoring. The results of acoustic emission monitoring of tensile test of SG tensile specimen were further verified and the results of standard tensile test were verified to confirm that it is feasible to monitor the acoustic emission of this new SG.
