Strengthening Mechanism and Microstructure of Deformable Ti Particles Reinforced AZ91 Composite
文献摘要：
In this study,the deformable titanium(Ti)particles reinforced AZ91 composite was successfully prepared by powder met-allurgy and subsequent extrusion.The mechanical properties and microstructural evolution of pure AZ91 and 5Ti/AZ91 composite were studied.The yield strength,ultimate tensile strength,and elongation of 5Ti/AZ91 composite are measured to be 212 MPa,323 MPa,and 10.1％,respectively.Microstructure analysis revealed that Ti particles are elongated along the extrusion direction,forming a discontinuous strip Ti particles,fine precipitated Mg17Al12 phase inhibits dynamic recrystal-lization(DRX)behavior through Zener pinning effect and hinders the growth of matrix grains,resulting in refiner grains of 5Ti/AZ91 composite.Heterogeneous deformed Ti particles and magnesium(Mg)matrix to generate additional heterogene-ous deformation-induced(HDI)strengthening.Heterogeneous deformation-induced strengthening mainly contributed to the increment of yield strength for 5Ti/AZ91 composite.
