Effect of Technologies Processing on Material Properties of Selected Aluminium Alloys

Abstract

The paper is concerned with an analysis of utility properties of selected aluminium alloys, namely EN AW 6082 (AlSi1MgMn), EN AW 6061 (AlMg1SiCu) and EN AW 7075 (AlZn5.5MgCu) with different technology of hot processing. The alloys were hot processed to reach T3 condition (solution annealing, cold forming and natural aging) and to reach T4 condition (solution annealing and natural aging). The following parameters were subject to evaluation: microstructure and sub-structure, mechanical properties (strength and plastic characteristics stated in Table. 1) as well as fatigue properties of these alloys assessed during alternative symmetrical stress in torsion. The paper was aimed to study the affect of processing technology of three aluminium alloys on their utility properties in the conditions of tensile stress and cyclic stress in torsion.

Experimental Study and Verification of New Monolithic Rotary Cutting Tool for an Active Driven Rotation Machining

“…AlZn5.5MgCu is one of the strongest aluminium alloys with a tensile strength of up to 600 Mpa (often referred to as aerospace duralumin), has the highest strength and hardness of all alloys and is also characterised by excellent polishability [ 19 ]. It is mainly used where a combination of high strength and low weight is important and for highly stressed structural parts.…”
