Microstructures and Mechanical Properties of ZA27-Al2O3 Composites Obtained by Powder Metallurgy Process
Апстракт
This paper describes a study of the microstructures and mechanical properties of Zn-matrix composites reinforced by 10 wt.% Al2O3 particles of 0.7 mu m average size. Commercial Zn-Al-Cu (ZA27) alloy was gas atomized and the resulting powder was mixed with an Al2O3 powder, and then hot pressed into cylindrical pellets. Metal powder and powder mixtures were pressed at 230 degrees C, for 45 mm under the pressure of 150 MPa. The compressive strength testing was performed in the temperature range from 20 degrees C to 160 degrees C, with a deformation rate of 2.4 x 10(-3)s(-1). The microstructures and the :fracture surface of the samples were investigated by optical and scanning electron microscopy.
