【Abstract】 This paper devotes an extended discussion on the basis of dislocation theory about the critical condition for attaining toughness -brittleness trans- formation in semi-brittle metallic materials. Further more, the micro factors which cause embrittlement of materials are brought into consideration separately in this papr.更多还原
