This work explored possibilities of biodegradable magnesium alloy Mg-3Y preparation by two modem powder metallurgy techniques-spark plasma sintering(SPS)and selective laser melting(SLM).The powder material was consolidated by both methods utilising optimised parame-ters,which led to very low porosity(about 0.3％)in the SLM material and unmeasurably low porosity in the SPS material.The main aim of the study was the thorough microstructure characterisation and interrelation between the microstructure and the functional properties,such as me-chanical strength,deformability,and corrosion resistance.Both materials showed comparable strength of about 110 MPa in tension and compres-sion and relatively good deformability of about 9％and 21％for the SLM and SPS materials,respectively.The corrosion resistance of the SPS material in 0.1 mol·L-1 NaCl solution was superior to the SLM one and comparable to the conventional extruded material.The digital image correlation during loading and the cross-section analysis of the corrosion layers revealed that the residual porosity and large strained grains have the dominant negative effect on the functional properties of the SLM material.On the other hand,one of the primary outcomes of this study is that the SPS consolidation method is very effective in the preparation of the W3 biodegradable alloy,resulting in material with convenient me-chanical and degradation properties that might find practical applications.
