al [13] reported that the fcc-Ti phase was observed in unmilled and milled (30 h) powders when quenched in water from 1200 °C. They concluded that the fcc-Ti phase was stress-induced during... size keeps decreasing when the fracture strength of the particles is equal or smaller than the stress caused by the collision [23]. Particles with an equiaxial shape showed the predominance of cold......
降低了晶界结合力,试样整体拉伸性能表现出随晶粒尺寸的减小而强度升高的趋势,但在U3试样中,拉伸强度提升的同时,伸长率并没有显著下降,超声振动加上充分的层间冷却实现了细晶强化,强度提升的同时塑性得以保留. 图11 典型C95220铸造铝青铜合金和电弧增材制造U2,C3和U3试样应力-应变曲线 Fig. 11 Comparison of stress-strain... and properties of laser cladded and solution-aging treated Ti6Al4V alloys[J].

the compressive stress-strain curve of Ti185 alloy at different sintering temperatures for 30 min. Samples with three different sintering temperatures have excellent compressive strength..., the sintered sample has high density, the reduced stress concentration caused by defects, and a significant strengthening effect on the matrix. On the other hand, the lamellar α phase with a higher aspect......
