Mikrostruktura odlewniczych stopów magnezu wzmacnianych cząstkami Al203
Полный текст в pdfАннотация
The article discusses problems of performing magnesium alloys composites, reinforced with Al2O3 particles. The chemical composition of casting magnesium alloys, most common alloy elements and their impact on alloy properties were described. The method of producing magnesium composites - „stir casting” and the impact of Al2O3 particles on properties of a composite were also described. Research were performed based on the AZ91D alloy for several different mixing times. The microstructure of an alloy and composite materials, including phases identification and quality of matrix-particle interphase were analysed. Based on the microstructure, the mixing efficiency was set. The percentage of Al2O3 particles in a composite was defined. The results of hardness and impact of mixing time on a microstructure and properties of a Mg-Al2O3 composite were shown.
