The influence of spark plasma sintering temperature on the mechanical properties and corrosion resistance of Zr_(65)Al_(10)Ni_(10)Cu_(15) metallic glass powder

摘要

Spherical Zr_(65)Al_(10)Ni_(10)Cu_(15) metallic glass (MG) powders were prepared using a high-pressure gas atomizer, followed by consolidation using spark plasma sintering (SPS) process. This investigation is to discuss the thermal properties, mechanical properties and corrosion resistance of MGs with the SPS temperature. The SPS bulk showed that both the mechanical properties and corrosion resistance improved with increasing the temperature. As the temperature became over the glass transition temperature (T_g), however, these properties dramatically lowered, corresponding to formation of crystalline phases.
