Magnesium alloys offer excellent properties with regard to application as degradable implant. The present study uses melt extracted magnesium fibers as the starting material for the sintering of highly porous magnesium bodies, i.e., from W4 and WZ21 alloys. Metallographic investigations show a very fine-grained microstructure which results in a lower corrosion rate of the high-purity, high-porous fiber structure compared to the ingot material.
