404 ショットピーニングを施したAZ31合金管の曲げ強度特性(GS1,4,11 機械材料・材料加工,研究討論セッション)
詳細
The effect of shot peening on the bending strength of an AZ31 magnesium alloy pipe was investigated. In the experiment, extruded pipes of 22 mm 0.D., 18 mm I.D., and 2 mm wall thickness were used. Shot peening treatments were applied to the surface of the workpiece using an impeller-type or an air-type peening machine. It was found that multiple deformation twins were formed during shot peening. The results of the present study revealed that the compressive yield stress of shot-peened pipes is strongly related to their bending strength.
