Resumen:
In pseudoelastic alloys, a fine-grained microstructure implies restrictions on the propagation and shrinkage of the martensitic phase. As a consequence, the pseudoelastic effect is adversely affected. For this reason, thermomechanical methods of grain growth that are both fast and applicable on an industrial scale are sought. In this paper, we present a novel and fast method to obtain single crystals of centimeter-order lengths. The process consists of combining two methods of abnormal crystal growth: directional annealing; and thermal cycling. This technique is applicable to alloys that have a parent single-phase high-temperature region and a two-phase, low-temperature region.
