Microstructure and Mechanical Properties of Magnesium Prepared by Spark Plasma Sintering

Article Preview

Magnesium powders were sintered by using spark plasma sintering (SPS) and conventional pressureless sintering (PLS) techniques at sintering temperatures ranged from 552°C to 605°C to investigate effect of sintering method on microstructure and mechanical properties of sintered magnesium. High densed magnesium could be obtained by using spark plasma sintering technique compared to conventional presureless sintering at the same sintering temperature. It was found that the ultimate tensile strength increased with increasing sintering temperature for both the materials sintered by PLS and SPS. The magnesium samples prepared by SPS showed better mechanical properties than those prepared by PLS. The microstructural observations revealed that the grain growth was not significant in SPS process compared to PLS, which would enhance the mechanical properties of the SPS sintered magnesium.
