Abstract
PURPOSE: To manufacture an alloy producing no Luders mark by homogenizing an Al alloy ingot contg. a specified percentage each of Mg, Zn, Cu and Ti at a specified temp. followed by rolling, heating and cooling under specified conditions.
CONSTITUTION: An Al alloy ingot consisting of 3.5W7% Mg, 0.5W2% Zn, 0.1W 0.3% Cu, 0.01W0.1% Ti and the balance Al with impurities is homogenized at 450W515°C, hot-rolled, cold-rolled, and finally treated by heating at 450W550°C for ≤3min and cooling to 150°C at ≤1,000°C/min average cooling rate. It is preferable that the amounts of the contained impurities are restricted to <0.1% each of Mn, Cr, Zr and V, <0.25% Fe and <0.2% Si.
