are quasi-cleavage fracture. Different types of dislocation structures were developed during high cycle fatigue deformation. Key words: Hf; single crystal superalloy; DD6; high cycle fatigue 1... plane, as shown in Fig.3. The presence of slip traces on the fracture surfaces provides another evidence for cyclic plastic deformation. At the crack propagation stage, feature fatigue striations......
parameters in this equation are explored experimentally.Considering the relation of crack growth and deformation properties,a simple andapplicable method is proposed to evaluate the fatigue crack growth...A NOVEL PARAMETER FOR EVALUATING THE FATIGUE CRACK GROWTH RATE IN CARBON STEELS H.Nisitani1,S.Q.Zhu2,N.KAWAGOISHI3,X.S.WANG2 (1.Faculty of Engineering,Kyushu Sangyuo University,Fukuoka,812,Japan......
