Effect of Mn on the mechanical properties and microstructure of reaction sintered Mo2NiB2 boride-based cermets

Abstract

This paper focused on the effects of Mn addition from 0 to 10wt% on the mechanical properties and microstructure of V added Mo2NiB2 based model cermets. Transverse rupture strength of the cermets increased with increasing Mn content and showed a maximum value of 3.5 GPa at 2.5 wt.%Mn, and then decreased with further increasing Mn content. Hardness increased monotonically from 86.4RA up to 10wt%Mn. The high TRS at 2.5 wt.%Mn was attributed to size refinement and homogeneous distribution of Mo2NiB2 complex boride resulting from Mn addition.
