Studies on the models of hot deformation of materials indicate that there is a linear relationship between the dissipation efficiency parameter of the dynamic materials model, and the intrinsic hot workability parameter of the polar reciprocity model, and both models need a stability criterion for delineating the regimes of flow instabilities in the processing maps.

Zr–Nb alloys are used in the nuclear and chemical industries, in which the welding of an end cap to a fuel rod is a critical issue in manufacturing processes. To identify the optimal process parameters for achieving good-quality welds, it is necessary to investigate the thermal environment in the fusion and heat-affected zones. A three-dimensional computational fluid dynamics analysis is performed with a volumetric heat source by simulating the interaction of the heat source and the material and by accounting for the phase change during welding. The model incorporates the buoyancy force and Marangoni stress and generates the temperature distribution, weld bead geometry and fluid flow in the weld pool during the laser welding process.
