Effects of V and Al on Microstructure and Room Temperature Fracture Toughness of Nb-Si In-situ Composites () 摘要:The effect of alloying elements V and Al on microstructure and room temperature fracture toughness of an experimental Nb-Si in-situ composite was investigated. The Nb-Si alloys with different amount of V and Al were prepared by non-consumable arc-melting furnace. The experimental......
microstructure with doublet tips in the axes direction. Observations for fracture surfaces show that the growth morphology of Mg32(Al,Zn)49 grains was truncated cubic, and its growth mechanism was also...Microstructure and growth morphology of Frank-Kasper phase in rapidly solidified Mg32Al17Zn32 ternary alloysZHU Man, YANG Gencang, WAN Diqing, WANG Zhijun, and ZHOU Yaohe State Key Laboratory......
the elongation increases with the increase of temperature. The results of SEM fracture analysis show that the tensile fracture is transgranular below 300 ℃, the morphology changes gradually from transgranular... properties of the casted sample were tested at 250, 300, 350, 400, 450, 475 and 500 ℃, respectively, after homogenizing annealing treatment. The high temperature deformation and fracture behavior......
