The ageing behavior of as-extruded ti_(P)/VW94 composites was *** peak hardness of the composites increases compared to the matrix alloy and the 5%ti_(P)/VW94 composite presents the highest peak hardness of 148.7 HV after aging for about 50 ***,the hardness increments first decrease and then slightly increase with increasing ti particle content due to the introduction of high-density dislocations by ti particles.

Novel titanium particles reinforced Zr-based bulk metallic glass composites prepared by infiltration casting

引用

Journal of University of Science and Technology Beijing 2008年第4期15卷 505-508页

作者： Cuimei Zhang Xidong Hui Meiling Wang Guoliang Chen State Key Laboratory for Advanced Metals and Materials University of Science and Technology Beijing Beijing 100083 China

A novel ti/Zr41.2ti13.8Cu12.5Ni10.0Be22.5 composite was successfully prepared by infiltrating the melt into sintered ti preform. It shows that the introduction of ti particles into the composite results in an increase in elastic strain to 3% and an enhancement of the strength up to 2.1 GPa. High specific strength has been obtained because of the decrease in density of the composite. It is suggested that an improvement in the mechanical properties of the composite may be attributed to the generation of multiple shear bands and some deformation in the ti particles.

Effects of hot extrusion on microstructure and mechanical properties of Mg matrix composite reinforced with deformable TC4 particles

Journal of Magnesium and Alloys 2020年第2期8卷 421-430页

作者： Xiaojun Wang Xiaoming Wang Xiaoshi Hu Kun Wu School of Materials Science and Engineering Harbin Institute of TechnologyHarbin 150001China

Mg matrix composites were often reinforced by non-deformable ceramic *** this paper,a novel Mg matrix composite reinforced with deformable TC4(ti-6Al-4 V)particles was fabricated and then *** evolutions of microstructure and mechanical properties of the composite during hot extrusion were *** extrusion refined giains and eliminated the segregation of TC4 ***4 particles,as deformable particles,stimulated the nucleation of dynamic recrystallization during ***,since the deformation of TC4 particles partly released the stress concentrations around them,the recrystallized grains are just slightly smaller around TC4 particles than that away from them,which is evidently different from the case in Mg matrix composites reinforced by non-deformable ceramic *** with AZ91 matrix composites reinforced by SiC particles,the present composite possesses the superior comprehensive mechanical properties,which are attributed to not only the strong interfacial bonds between TC4p and matrix but also the deformability of TC4 particles.
