; 文献标志码:A Effect of aging treatment on intergranular corrosion of spray forming 7075 alloy SU Rui-ming, QU Ying-dong, LI Rong-de, XIE Qi-ming, YOU Jun-hua (School of Materials Science and Engineering, Shenyang University of Technology, Shenyang 110870, China) Abstract: The microstructure, mechanical properties and intergranular corrosion (IGC) behavior of spraying forming 7075 alloy......
with the content further increasing to 5 wt%.The coercivity of the hot-deformed magnets with 4 wt% and without MM-Cu addition is 948 and 683 kA/m,respectively.Nearly all the platelet-shaped grains are isolated by the thickened intergranular phase after MM-Cu addition.Moreover,the average grain size of the magnets with MM-Cu addition decreases compared with that of the magnet without MM-Cu......

Effect of Yb addition on strength and fracture toughness of Al-Zn-Mg-Cu-Zr aluminum alloy ZHANG Zhuo(张 茁)1, CHEN Kang-hua(陈康华)1, FANG Hua-chan(方华婵)1, QI Xiong-wei(齐雄伟)1, LIU Gang(刘 刚)2 1. State... of Yb addition on the strength and fracture toughness of Al-Zn-Mg-Cu-Zr aluminum alloy was investigated by measuring tensile properties and fracture toughness. The surface morphology was observed......
for the intergranular fracture. 5 Conclusions 1) Simultaneous addition of Sc and Zr can greatly improve the tensile property and make the peak aging arrive earlier for Al-Zn-Mg-Cu alloys. The tensile property... Effect of minor Sc and Zr addition on microstructures and mechanical properties of Al-Zn-Mg-Cu alloys ZOU Liang(邹 亮), PAN Qing-lin(潘清林), HE Yun-bin(何运斌), WANG Chang-zhen(王昌臻), LIANG Wen-jie(梁文杰......
Micromechanical model for competition between intergranular and intragranular fracture in 7××× aluminum alloys ZHANG Xin-ming(张新明), LIU Wen-hui(刘文辉), TANG Jian-guo(唐建国), LIU Sheng-dan(刘胜胆) School... features was created. The competition between intergranular and intragranular fracture was investigated by comparing the void growth velocity between PFZ and matrix. The effects of void aspect ratio......
resistance of the alloy and the mechanisms were investigated. The results show that the intergranular corrosion resistance can be improved substantially without the degradation of mechanical... of M23C6 type carbides appears at the grain boundary in the alloy by EPT, which decreases the depletion extent of the alloying elements at the grain boundary substantially. As a result, the intergranular......
words: 2197 Al-Li alloy; aging; mechanical property; intergranular corrosion; exfoliation corrosion CLC number: TG146.2 Document code: A 1 INTRODUCTION The addition of 1% Li to Al alloy can...: The effects of aging on mechanical properties, intergranular corrosion and exfoliation corrosion behaviors of a 2197 type Al-Li alloy were investigated, and the mechanisms were studied through microstructure......
and the elongation percent of the transverse bending reached max value (about 5%) at 1 100-1 200 ℃. After the addition of carbon, the microhardness in the grain boundary is about 150 MPa higher than that in the grain. The fracture type of pure Mo is intergranular fracture, the grain boundary strength of Mo-C alloy is strengthened due to the addition of carbon and the fracture type is changed......
Effect of interlayer addition on microstructure and mechanical properties of NiTi/stainless steel joint by electron beam weldingH.Niu1,2,H.C.Jiang1,M.J.Zhao1,L.J.Rong11. CAS Key Laboratory of Nuclear..., and the joints without interlayer, adding Ni interlayer and adding Fe Ni interlayer exhibit cleavage fracture, intergranular fracture and mixed fracture composed of cleavage and tearing ridge, respectively......
