抄録

Uniaxial tensile tests, cylindrical and square shell deep drawing tests of aluminum alloy sheets from RT to 250°C temperatures were carried out in order to investigate temperature dependence of mechanical properties and deep drawability. In these warm working temperatures, tensile strength (TS) decreases and elongation (El) is nearly same from RT to 100°C, but it increases largely with the increase of temperature from 150 to 250°C. This change of El mainly depends on local elongation (L.El) . Cylindrical shell deep drawability increases with ambient temperatures. Square shell deep drawability increases largely from 200°C to 250°C, but it is nearly same from RT to 150°C. ΔLDR (limiting drawing ratio) shows the effect of working temperature from the LDR of RT. The effecive experimental equation between ΔLDR and mechanical properties (TS, El, L.El) is developped.
