Microstructural Path of Recrystallization in an Electron Beam Melted Ta-10wt% Alloy
The recrystallization of an electron beam melted Ta-10wt%W alloy deformed by cold swaging with reductions in area of 41 and 95% and annealed between 1300 oC and 1700 oC is quantitatively described. The recrystallized volume fraction and the interface area per unit of volume are measured. From these quantities the microstructural path is analyzed. Based on the available measurements the nucleation and growth of recrystallization in this alloy is discussed. The kinetic analysis is difficult in this case due to the large initial grain size of the specimens.
