METHOD FOR MANUFACTURING SCANDIUM ADDED ALUMINUM ALLOYS USING SOLUTION TREATMENT AND NATURAL AGING METHOD FOR THE ENHANCEMENT OF STRENGTH AND ELONGATION OF THE SAME

摘要

PURPOSE: a kind of manufacture addition scandium-aluminum alloy solution treatment and natrual ageing method provide to obtain desired intensity and elongation using enhancing strength and elongation and pass through the processing and physical deterioration process of control solution. ;CONSTITUTION: adding the manufacturing method of scandium-aluminum alloy, keeps comprising steps of controlling the amount for recrystallizing score and after the casting a vacancy cluster and being homogenized Al-Zn- (magnesium)-copper ()-titanium (zirconium)-(short circuit) alloy in room temperature to enhance intensity. The alloy includes 5-20weight% zinc, the magnesium of 0-15weight%, the Zr in the Cu of 0-8weight%, 0-1weight%, 0-1weight% Ti, and 0.01-1.Scale in 0weight%;The 2013 of copyright KIPO submissions;[Reference numerals] Casting (AA); Homonizing ( BB ); (CC) it squeezes or forges; Fractional domination processing temperature, refrigerating mode are recrystallized according to solid solution (DD); (EE) physical deterioration
