The effects of temperature and forming speed on the forming limit diagram for type 5083 aluminum-magnesium alloy sheet
TL;DR: In this article, the effects of forming speed and temperature on the forming limit diagram (FLD) were investigated experimentally for a fine-grain Al-Mg alloy (5083-O) sheet by performing stretch-forming tests at various forming speeds (0.2-200mm-min−1) at several temperatures from 293 to 573
Journal ArticleDOI
Deep drawability of type 5083 aluminium–magnesium alloy sheet under various conditions of temperature and forming speed
Tetsuo Naka,Fusahito Yoshida +1 more
TL;DR: In this article, the effects of forming speed and temperature on the deep drawability were investigated for a fine-grain Al-Mg alloy (5083-O) sheet by performing cylindrical deep drawing tests at various forming speeds (0.2 −500mm min −1 ) at die temperatures of 293 −453 K (the die was heated, whilst the punch was water-cooled during the tests).
Journal ArticleDOI
Effects of temperature on yield locus for 5083 aluminum alloy sheet
TL;DR: In this article, the effect of forming temperature on the yield locus was investigated for a fine-grained Al-Mg alloy (5083-O) sheet and the results showed that the size of the locus drastically decreased with increasing temperature.
Journal ArticleDOI
Effects of strain rate, temperature and sheet thickness on yield locus of AZ31 magnesium alloy sheet
TL;DR: In this article, the effects of strain rate, temperature and sheet thickness on the yield locus of magnesium alloy (AZ31) sheets with different sheet thickness (0.5 and 0.8mm) were experimentally investigated.
Journal ArticleDOI
