摘要: Twinning plays important roles in HCP metals and those FCC with low stacking fault energy. The structural difference of two types makes quite different contributions twinning to plasticity. variety grain orientation polycrystalline causes the inhomogeneous occurrence further distinct transformation kinetics as strain increases texture develops. This changes finally work hardening behavior mechanical properties. paper reveals dependency on an TWIP (twinning induced plasticity) steel high Mn content a magnesium alloy using electron-backscatter-diffraction (EBSD) technique, analyzes characteristics by Schmid factor calculation. In addition, relation shear banding, well their influence properties are discussed.
