[ 1 ] - بررسی اثر اکستروژن در کانال زاویه دار همسان بر رفتار پیر کرنشی دینامیکی یک آلیاژ Al-Mg-Si-Cu

An Al-Mg-Si-Cu alloy was subjected to tensile testing, both under solutionized and ECAE-ed conditions, using strain rates of 10-4 s-1 to 10-1 s-1 at temperatures of 25 ˚C to 325 ˚C to investigate the dynamic strain aging (DSA) phenomenon in the alloy. Negative strain rate sensitivity (m) and increasing ultimate tensile stress were observed in the DSA region with increasing temperature . Regardi...
