Microstructural evolution and mechanical properties of Mg composites containing nano-B4C hybridized micro-Ti particulates

摘要: Abstract In this work, the microstructural evolution and mechanical properties of extruded Mg composites containing micro-Ti particulates hybridized with varying contents nano-B 4 C are investigated, compared Mg-5.6Ti. Microstructural characterization showed presence uniformly distributed particles embedded that resulted in significant grain refinement. Electron back scattered diffraction (EBSD) analyses Mg-(5.6Ti +  x -B C) BM hybrid addition particle relatively more recrystallized grains, realignment basal planes extension weak fibre texture when to The evaluation indicated improved strength ductility retention composites. When Mg-5.6Ti, superior attributed nano-reinforcements, uniform distribution particles, better interfacial bonding between matrix reinforcement refinement achieved by addition. enhancement obtained can be spread favourable plane orientation due nano B
