Zr-Nb alloys are mainly used in the nuclear energy industry. A study was carried out with the aim of understanding the physical phenomena involved during the hot extrusion stage and modeling these phenomena with numerical simulations. However, it is first essential to determine the material parameters, including reduced mobility during pure grain growth. Experimental and numerical campaigns are therefore carried out to define this parameter, material and model dependent. Consequently, this study focuses exclusively on the influence of niobium content on the grain growth kinetics of Zr-Nb alloy.
