Foamed magnesium alloy has similar porosity and mechanical properties to biological bone, and is often used as a substitute material for biological bone. AZ91 magnesium alloy has high corrosion resistance and is suitable as a substitute material for biological bone. In this paper, AZ91 magnesium alloy powder is used as the raw material and urea is used as the pore-forming agent. The powder is compressed into a cylindrical sample under a pressure of 11MPa, and sintered at different temperatures. Conduct metallographic observation and mechanical performance test on the sample. The results show that the sintering temperature is between 520-550℃ is the most suitable, the compressive strength of the sample is up to 9.14MPa, the porosity is large and the pore size is uniform, which meets the performance requirements of bone substitute materials.
Key words: AZ91 magnesium alloy; sintering temperature; mechanical properties; porosity
