, respectively. The fracture analysis results show that the fracture location changes from ISZ to DZ during room temperature tensile test with the increase of bonding temperature. However, when tested at high temperature, the facture always occurs at ISZ. Key words: GH4169 alloy; transient liquid phase (TLP) bonding; interfacial microstructure; bonding temperature; fracture analysis 基金项目:国家自然科学基金资助......
Fractal Dimensions of Hydrogen Induced Brittle Fracture of Titanium AluminideYue ZHANG Yanbin WANG Lijie QIAO Wuyang CHU Chimei HSIAO Dept.of Materials Physics,University of Science and Technology... and the fractal dimension DF of the fracture surface was derived,i.e,InK1*=(1/2)In2γE’+(1/2)In(df/L0)(1-DF)The real surface energy can be calculated based on the measured linear relation of the InK1* vs......
Mechanical Properties and Fracture Behaviour of Multilayer Alumina Composites郑新国1,ZHAO Fei2,张金咏21. Railway Engineering Research Institute of China Academy of Railway Science2. State Key Lab.... The fracture behaviour of the Al2O3/Kevlar multilayer composite was studied to find a reason for this improvement. The results showed that the complex and asymmetrical stresses occurring in the Kevlar......
In-situ Observation of Tensile Fracture in A357 Casting AlloysZhongwei Chen,Xiaolei Hao,Yu Wang,Kai ZhaoState Key Laboratory of Solidification Processing,Northwestern Polytechnical University摘 要:The mechanism of damage evolution and fracture in A357 casting alloys was investigated by in-situ scanning electron microscopy(SEM) tensile testing.Different......
at the interface. The addition of Ni and Zr modified the influence of the two-stage solution and inhibited the growth of the 7090/SiCp composite grain size. Heat treatments can significantly improve the fracture toughness of the composite. The fracture toughness first decreases then increases with the elongation of the aging time. Key words: Al matrix composite; spray co-deposition; heat treatment; solid......
