Stability of the beta phase in Ti-Mo-Cr alloy fabricated by powder metallurgy
A new b Ti alloy was designed and fabricated by powder metallurgy process using pure metallic powders. The addition of Mo and Cr increased the stability of the b phase. By contrast, O promoted a phase formation upon cooling. The addition of 18%Mo and 10%Cr stabilized the b phase into ambien...

| description | A new b Ti alloy was designed and fabricated by powder metallurgy process
using pure metallic powders. The addition of Mo and Cr increased the
stability of the b phase. By contrast, O promoted a phase formation upon
cooling. The addition of 18%Mo and 10%Cr stabilized the b phase into ambient
temperature. O increased the critical cooling rate of formation of a phase
due to the prediction of the continuous cooling transformation diagram
calculated by the Java-based Material Properties software. Sintering and
solution treatment also enhanced the alloying behavior of pure powders to
their designated chemical compositions. Hardness of the alloy decreased with
increasing Mo and Cr content, which led to the decrease of a phase. The
Ti-18%Mo-10%Cr alloy exhibited better corrosion resistance than a commercial
Ti-6%Al-4%V alloy, which is used as current biomaterial. |
