Study on the Test Conditions of Micro-hardness
Several experiments of micro-hardness have been performed on Al and Mg single crystal in order to clarify the effect of test conditions. The micro-hardness increased rapidly at first with the increasing of test load in the small load range, then decreased gradually and became finally independent of the test load.
