Empirical Relationship between Hardness and Tensile Properties of High Pressure Torsion-processed Al 6061

Research output: Contribution to journalConference article

Abstract

Improved strength is the ultimate goal of advanced material processing technique, including high-pressure torsion (HPT). To evaluate this goal, it requires determination of strength properties of the processed sample. While tensile test involves destructive test procedures, hardness is a closely related mechanical property in evaluating strength. This illustrates the need for a reliable hardness-tensile properties relationship. This paper determined an empirical relationship between hardness and several tensile properties i.e. ultimate tensile strength, Young modulus and tangent modulus, of HPT-processed Al 6061 samples. As results, an acceptable linear correlation for each property was obtained with a unique relationship. The degree of agreement between the studied properties and hardness was discussed. With recent advanced in computational method, the derived empirical relationships could optimise the HPT processing and aid the sample behaviour control and prediction.
