چکیده انگلیسی
The present study illustrates the structural and mechanical properties of magnesium composites containing Ni50Ti50 metallic glass reinforcement particles. Novel Mg-composites containing 3, 6 and 10Â vol.%Ni50Ti50 amorphous particulates were synthesized using the microwave assisted rapid sintering technique followed by hot extrusion. The developed Mg-composite materials were investigated for their microstructural and mechanical properties. Microstructural studies revealed the retention of amorphous structure of Ni50Ti50 reinforcement and its fair distribution in developed Mg/Ni50Ti50 composites. Mechanical property evaluation under indentation and compression loads showed significant enhancement in strength properties (microhardness:+78%, 0.2CYS:+79%, UCS:+70%, 0.2TYS:+95%, UTS:+50%) without compromising the compressive ductility. For the first time, tensile properties of such amorphous particles reinforced Mg-composites were studied and the results showed â¼98% increase in 0.2TYS and â¼50% increase in UTS. The tensile ductility was adversely affected. However, the obtained values are comparable to that of conventional Mg-composites. The observed mechanical response discussed in terms of structure-property relationship highlights the efficacy of amorphous Ni50Ti50 reinforcement particles and the energy efficient microwave sintering approach to produce high performance magnesium composites.
