mikrostruktura - Opis:
- Magnesium alloys containing yttrium and neodymium are known to have high specific strength, good creep and corrosion resistance up to 250°C. The addition of ceramic particles strengthens the metal matrix composite resulting in better wear and creep resistance while maintaining good machinability. In the present study, WE43 magnesium matrix composite reinforced with SiC particles were fabricated by stir casting. The microstructure of the composite was investigated by optical microscopy, quantitative metallography, scanning electron microscope and XRD analysis. Microstructure characterization of WE43 MMC showed homogeneous reinforcement distribution and presence of the small amount of porosity at the interface. A thin layer consists of zirconium-rich particles was observed at the interface. In the microstructure, inclusions of the yttrium oxide were found. The presence of SiC particles assisted in improving hardness and in decreasing the ultimate tensile strength, yield tensile strength and elongation.
