Abstract
Mechanical alloying (MA) is an efficient approach for fabricating ODS alloys and structural materials including vanadium alloys for fusion and fission applications. Dissolution behavior of the alloying elements is a key issue for optimizing the mechanical alloying process in fabricating vanadium alloys. This paper studies the MA process of V-4wt.%Cr-4wt.%Ti alloy. The outcomes of the MA powders in a planetary ball mill are reported in terms of powder particle size, morphology and composition evolution. The impact of spark-plasma sintering process on the mechanically alloyed powder is analyzed. The microstructure of the V-4wt.%Cr-4wt.%Ti alloy prepared by mechanical milling is investigated with a X-ray diffractometer and scanning electron microscope.
