ON MECHANICAL BEHAVIOUR OF PRESSURE-ASSISTED, SINTE RED Al-Mg COMPOSITE

Abstract

Lightweight materials like Al-Mg composite are attractive especially for aerospace or automotive industry. Current paper investigates mechanical behaviour of hot-pressed, reactive sintered Al-Mg composite with initial Mg volume content of 60% using finite element simulation. Conducted numerical simulations study effect of the porosity on mechanical behaviour. Overall porosity (in percent) is decisive factor for mechanical behaviour of investigated Al-Mg composite rather than number or size of pores.
