WebThe microhardness variation was low in the HAZ regions of both metals. This is in the range between 90 HV and 110 HV for Cu, and between 60 HV and 80 HV (HV min and HV max) for the Al. It was observed in all the welds, the higher Vickers microhardness values in a range of between 130 HV and 350 HV were measured in the TMAZ and the SZ of the weld. WebAug 26, 2024 · Microhardness is a broadly used term referring to the testing of hardness involving materials by using small applied loads. A more appropriate term to describe this is microindentation hardness testing. In this testing method, the use of a diamond indenter with a particular shape is used to make an impression called a "test load" or "applied ...
