Mechanical Alloying of β‐Type Ti–Nb for Biomedical Applications

Abstract

Abstract β‐Type Ti–Nb powders which are needed as precursors for porous implant materials were produced by mechanical alloying of elemental powders. The effect of different fractions of the inorganic milling agent NaCl on the phase reactions during the milling process was investigated by means of X‐ray diffraction and scanning and transmission electron microscopy. It was demonstrated, that addition of ≥2 wt% NaCl during continuous ball milling is efficient for establishing a nanostructured β‐phase alloy and for the achievement of high powder yield.
