Effects of milling time on powder packing characteristics and compressive mechanical properties of sintered Ti-10Nb-3Mo alloy

• We investigated the influence of milling time on the packing characteristics and compressive mechanical properties of a biomedical Ti alloy.
• Increasing milling time led to a significant decrease in the compressive mechanical properties.
• Powder packing density was adversely affected at longer milling times.

The influence of milling time on the powder packing characteristics and compressive mechanical properties of a biomedical Ti-10Nb-3Mo alloy (wt.%) was investigated. Ball milling was performed on elemental metal powders at different milling times of 0 (blended), 2, 4, 6, 8, and 10 h. This article demonstrates that despite the beneficial effects of ball milling technique in the mechanical alloying of the Ti-based alloy, the ball-milled powders synthesized at longer milling times can adversely affect the packing density and significantly diminish the compressive mechanical properties of the sintered powders.
