The local squeezing method with pin was adopted to prevent internal defects such as gas blowholes and shrinkage porosities in the local area of ADC12 die-castings. This treatment remarkably improved the fatigue strength of the die-castings. The smaller the size and density of defects, the higher is the fatigue strength is.
