THE EFFECT OF HEAT TREATMENTS ON MECHANICAL PROPERTIES OF ALUMINUM ALLOY AA 2024-T6

Abstract

This paper is aimed to study the effect of solution heat treatment on mechanical properties of Al alloy AA 2024-T6 (Tensile, hardness, wear resistance), many specimens were prepared according to ASTM and then heated to 500ºC for one hour and water quenched.Artificial aging carried out at 190ºC for (1, 2, 5) hours and cooled slowly by air to show the effect of aging time on mechanical properties, many examinations (Microstructure, hardness Tensile and wear test) were done for specimens.From the obtained results it can be see that heat treatment contributed in mechanical properties improvement.
