Texture in NiTi-Based Shape Memory Alloys Produced by Twin Roll Casting

Abstract:

Two shape memory alloys with nominal chemical composition: Ni50Ti50 and Ni47Ti50Co3 were produced using twin roll casting technique (TRC). Relatively high cooling rate realized during solidification causes directional heat flow. In result of that, high textured strips were produced. However, the total amount of the preferentially oriented grains differs between surface and cross-section of the strip. At surface, where the crystallization of the grains is the most intensive amount of the grains can reach about 77%. At the cross-section of both strips, where the solidification rate decreased, the total amount of the textured grains was not higher than 57%.
