| Abstract: | Gas blisters in the surface of aluminum alloy rotary forged wheels can be observed because of the sub-surface porosity in stocks and lubricant falling off from the mould. However, the surface blister can be controlled effectively by strengthening purification of the melt, adjusting the casting parameters and establishing the mould cleaning system . |
