UT ultrasonic testing

Ultrasonic fatigue properties experiments have been performed with base metal and welded joints of 16Mn steel using a home-made ultrasonic fatigue testing system.

使用自行研制的TJU-HJ-I型超声疲劳试验系统装置进行了16Mn钢母材和焊接接头试件的超声疲劳性能试验,以探索其在超长疲劳寿命区间的疲劳行为。

Experiments are conducted to determine the gigacycle fatigue behavior of nodular cast iron GS51 by ultrasonic fatigue test system.

应用超声疲劳试验技术,完成了20kHz频率下(R=-1,R=0 1)的疲劳试验,获得球墨铸铁GS51在亿周次范围内的疲劳性能。

Ultrasonic fatigue tests were carried out on Q235B base metal and welded joints by an ultrasonic fatigue test equipment in order to investigate their super high cycle fatigue properties.

用超声疲劳试验装置对Q235B母材及焊接接头试件进行超声疲劳试验,研究其在超高周疲劳寿命区间的疲劳性能。
