In this study, instrumented indentation testing was conducted at room temperature for the investigation of the effect of strain rate on the hardness and yield strength in the weld zone of a commonly used structural steel, SM520. A number of indentation tests were undertaken at a number of strain rate values from s −1 to s −1 in the weld metal (WM), heat-affected zone (HAZ), and base metal (BM) regions of the weld zone. | Indentation for investigation of strain rate effect on mechanical properties in structural steel weld zone
