Low-temperature accelerated sintering of high-performance oxide dispersion strengthened ultrafine grained Mo alloy

●Accelerated sintering can be achieved in Mo-ZrO2 system at low temperature.●Grain boundary diffusion is responsible for the accelerated sintering of Mo-ZrO2 system.●Grain boundary migration can be significantly restricted due to the presence of intergranular ZrO2 particles●Mo-ZrO2 alloy exhibits a stable high-strength performance characteristic even under high temperatures.
