The present work deals with the kinetics of precipitation of a CuAlBe single crystal alloy considering the influence of a pre-strain by wire-drawing. The single crystal is submitted to annealing parameters in order to obtain and compare the experimental starting points of the «time-temperature-precipitation» diagram without and with prestrain. Each sample has been observed by optical microscopy. Macroscopic tensile tests at room temperature were also undertaken to analyze the influence of wire drawing on the mechanical characteristics of the CuAlBe single crystal shape memory alloy.
