Structural changes of the AlMgSiCu alloy type caused by different thermomechanical and laser treatment regimes

Abstract

The wide application of the AlMgSiCu alloy type in almost all industry branches, needs permanent improvement of their properties. This paper deals with specific structural changes of alloy caused by thermo mechanical and laser treatment by different operation dynamical regimes of treatment (ruby laser; λ = 6694,3 x 10-9; Q switch). Structural changes are observed by transmission (TEM) and sening (SEM) microscope. The testing results are presented micro graphically. Special attention is aroused by changes in material structure caused by laser treatment.

Široka primena legura tipa AlMgSiCu u gotovo svim industrijskim granama zahteva njihovo stalno usavršavanje i poboljšanje njihovih osobina. Ovaj rad razmatra specifične strukturne promene legure uzrokovane termomehaničkom i laserskom obradom različitim radnim dinamičkim režimima obrade (ruby laser; λ = 6694,3 x 10-9; Q switch). Strukturne promene su posmatrane transmisionim (TEM) i sening (SEM) mikroskopom. Rezultati ispitivanja su prikazani mikrografijom. Posebnu pažnju pobuđuju promene u strukturi materijala prouzrokovane laserskom obradom.
