Small concentrations of Sb dopant in Cu can increase the grain boundary energy which suppresses grain growth. XRD results show that after annealing the CuSb alloy, the relative intensities of the (111) and (420) orientations increase. The grain growth results indicate that the Sb inhibits grain growth in Cu and keeps the microstructure intact at higher temperatures.
