Investigation of thickness and thermal treatments on the deep drawing process for the aluminum plate
Effective parameters on deep drawing include punch diameter, mold diameter, punch speed, power of preservative sheet, friction, traction and depth. In this work, the effect of precipitation hardening in 2618Al alloys was studied. In 2618 alloy the LDR values vary with the condition of heat treatment...

| Summary: | Effective parameters on deep drawing include punch diameter, mold diameter, punch speed, power of preservative sheet, friction, traction and depth. In this work, the effect of precipitation hardening in 2618Al alloys was studied. In 2618 alloy the LDR values vary with the condition of heat treatment and the best condition at the value of 1.33 was obtained. Comparison of LDR in different conditions had shown that precipitation hardening cause decrement in limiting drawing ratio and consequently is detrimental to drawing ability. In 2618 alloy at SA and SW conditions, the LDR was decreased. In this paper, the effect of temperature on earing in 2618 Al alloy was also discussed. Results show that at the temperature at 350oC the amount of earing is least. |
