Destructive Testing (DT)
Microhardness Testing
Vickers microhardness measurement under low loads to determine the hardness distribution of thin sections, coatings and welded zones.
Microhardness testing measures the hardness of thin sections, coatings, heat-affected zones and individual microstructural phases using low test loads. In the Vickers method, a square-based pyramidal diamond indenter is pressed under a low load and the diagonals of the impression are measured under a microscope. In welded joints, a hardness traverse is performed to determine the regional hardness distribution. In our laboratory, measurements down to loads of 50 grams can be performed with a QNESS Q 10M Automatic Vickers Hardness Tester.
