Metal Injection Molding Ti-6A1-4V-0.5B Titanium Alloy MIM Parts
The micro -tissue grains of the titanium -based composite material are obviously refined. The microstrip organization is used by alpha phase (chip -shaped or spherical), crystal boundary β phase, short stick -shaped second phase TIB phase, irregular spherical particles, and has floating The second phase of the convex feels composed of TIC.

From the above table, it can be clearly seen that 0.5%B is added on the basis of Ti-6AL-4V. When the alloy elastic modulus E is 145GPa, when adding 0.5%B and 0.5%C, the intensity increases to 1307MPa, but the plasticity is significantly reduced Essence When adding 0.5%B, 0.5%C, and 0.15%Y, the ZTC4/B/C/Y -titanium -based composite material formed has a good strong plasticity, its RM is 1240MPa, RP0.2 is 1129MPa, A is 10 for 10 %, Z is 15%, E is 155GPa.
