Abstract:
In the present study a new approach on strengthening of innovative high-temperature Me-Si-B (Me = Mo, V) materials by Y2O3 particles is presented. This approach combines the oxide dispersed strengthening (ODS) mechanism and additive processing of innovative intermetallic materials. To this end, gas atomized powder material, suitable for additive manufacturing, was doped with Y2O3 particles. Bulk materials were manufactured via direct energy deposition (DED), which is an efficient method to generate crack-free Me-Si-B alloys. The DED process further allows the homogeneous distribution of Y2O3 particles in the intermetallic matrix. Hardness measurements as well as uniaxial compression tests depict the potential of novel Y2O3 reinforced Me-Si-B alloys.
