Abstract

Abstract: Synthesis of a ferritic ODS steel Fe-9Cr-0.5Y2 O3 was carried out to develop as a candidate for nuclear fuel cladding material. The ODS steel was fabricated by powder metallurgy method with mechanical alloying, compaction and plasma sintering process. Effects of heat treatment on microstructure was investigated to enhance the mechanical properties. The heat treatment was carried out by annealing and tempering processes at temperatures of 900°C and 670°C with reference to the Fe-Cr phase diagram. Characterization was carried out using SEM-EDX and XRD test for microstructural analysis and Vickers hardness measurement. It is revealed that the heat treatment process will change the grain size and phase that affected the hardness of material.
