Evolution of microstructures and mechanical properties of spark plasma sintered Fe-Cr-Nb alloys

Present study investigates microstructural stability and mechanical properties of spark plasma sintered Fe-Cr-Nb alloys for its nuclear first wall reactor application. The nanostructured alloys were prepared by mechanical alloying (MA) for 25 h in argon atmosphere (purity
