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.

Detect the titanium -based composite material of Example 1 to Example 7. As a result, see Table 1:

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.
