Combined Effect of Annealing Temperature and Pre-deformation on the Superelastic Behaviors of NiTi Shape Memory Alloys
The combined effect of annealing temperature and pre-deformation on the superelastic behaviors of NiTi shape memory alloy wires was investigated by testing two types of samples with 72 and 35% area reduction. It is found that the annealed samples with 72% area reduction exhibited larger martensitic transformation stress, and the annealed samples with 35% area reduction exhibited superior superelastic cycle stability. The stress hysteresis of martensitic transformation for both two types of samples decreased with decreasing annealing temperature. In addition, pre-deformation enhanced the superelastic cycle stability and increased the stress hysteresis of the NiTi wires with 72% area reduction, but it had little effect on the stress hysteresis of the NiTi wires with 35% area reduction.
期刊介绍：
ASM International''s Journal of Materials Engineering and Performance focuses on solving day-to-day engineering challenges, particularly those involving components for larger systems. The journal presents a clear understanding of relationships between materials selection, processing, applications and performance.
The Journal of Materials Engineering covers all aspects of materials selection, design, processing, characterization and evaluation, including how to improve materials properties through processes and process control of casting, forming, heat treating, surface modification and coating, and fabrication.
Testing and characterization (including mechanical and physical tests, NDE, metallography, failure analysis, corrosion resistance, chemical analysis, surface characterization, and microanalysis of surfaces, features and fractures), and industrial performance measurement are also covered
