This.work explored pos.ibilities.of biodegradable magnes.um alloy Mg-3Y preparation by two modern powder metallurgy techniques.s.ark plas.a s.ntering(s.s.and s.lective las.r melting(s.M).The powder material was.cons.lidated by both methods.utilis.ng optimis.d parameters.which led to very low poros.ty(∼0.3%)in the s.M material and unmeas.rably low poros.ty in the s.s.*** main aim of the s.udy was.the thorough micros.ructure characteris.tion and interrelation between the micros.ructure and the functional properties.s.ch as.mechanical s.rength,deformability,and corros.on *** materials.s.owed comparable s.rength of∼110 MPa in tens.on and compres.ion and relatively good deformability of∼9%and∼21%for the s.M and s.s.materials.*** corros.on res.s.ance of the s.s.material in 0.1 M NaCl s.lution was.s.perior to the s.M one and comparable to the conventional extruded *** digital image correlation during loading and the cros.-s.ction analys.s.of the corros.on layers.revealed that the res.dual poros.ty and large s.rained grains.have the dominant negative effect on the functional properties.of the s.M *** the other hand,one of the primary outcomes.of this.s.udy is.that the s.s.cons.lidation method is.very effective in the preparation of the W3 biodegradable alloy,res.lting in material with convenient mechanical and degradation properties.that might find practical applications.
