THE APPLICATION AND EFFECTS OF THIN SHEET HARDNESS REFERENCE MATERIALS WITHOUT AGING EFFECT

Li Heping and Zhou Xing

Abstract

Hardness test methods are widely used in mechanical properties test area. While reference materials are essential important tools to control test accuracy or uncertainty. According to current test method standards, the thickness of hardness reference materials must be not less than 6 mm for Rockwell hardness or not less than 5 mm for Vickers hardness. To measure thinner sample which is commonly used in industry, and to guarantee the test results, a thin sheet reference sample is demanded.
