K-0719 Observation of Microscopic Deformation Behavior of Pure Aluminum using Ultra-Micro Hardness Tester

Abstract

It is well-known that the hardness of material is related to its mechanical characteristics. In the present study, the evaluation of the microscopic inhomogeneity of polycrystalline pure aluminum is performed by measuring the hardness of respective grains with the recently developed ultra-micro hardness tester. The relationship between the increase in the hardness caused by the work-hardening of the metal and the deformation of respective grains are studied.
