[ 1 ] - بررسی تأثیر فرایند اکستروژن در کانالهای هممقطع زاویهدار بر ریزساختار و خواص مکانیکی آلیاژ برنج 60-40
Equal Channel Angular Pressing (ECAP) is currently one of the most popular methods for fabricating Ultra-Fine Grained (UFG) materials. In this study, mechanical properties of the 60-40 two phase brass processed were evaluated by ECAP. The samples were repeatedly ECAP-ed to strains as high as 2 at a temperature of 350 ◦C using route C. The microstructure of the samples showed that small grains w...
[ 2 ] - resistance spot welding of nanostructured Al 2024 alloy and Evaluation of mechanical properties Weldment
In this research in order to improve the mechanical properties of Aluminium alloy 2024, nanostructure Aluminum sheets were first produced by Cryorolling process and then was welded by resistance spot welding method. For this purpose, the samples solution treated at 495˚C for 55 minute and subsequently cryorolled up to 85% reduction in thickness. For obtaining simultaneous strength and ductility...
