Research on Properties of Ternary Boride Hard Alloy Materials Added Nickel and Chromium

摘要

Using Mo powder, B-Fe alloy powder and Fe powder as raw materials, adding Ni and Cr respectively, with proper forming additives, the green body is formed by coining. The ternary boride hard alloy material is fabricated by liquid phase sintering technology. The influence of different content of Cr and Ni on mechanical properties is studied respectively. The optimal content of Cr and Ni and the optimal temperature are found.
