最初非晶态的Ti50Ni25Cu25熔纺带材通过快速热退火处理以50℃/s的加热速率进行结晶。该带材在500℃退火仅10s后就完全结晶，表现出良好的超弹性和形状记忆效应。当退火时间在60s左右时，带材的性能达到稳定状态。目前的研究表明，在 500°C 下进行短时间退火对于使初始非晶熔纺带材获得良好的性能非常重要。从微观结构的演变来讨论其原因。
The initially amorphous Ti50Ni25Cu25melt-spun ribbon was crystallized through rapid thermal annealing treatment at a heating rate of 50°C/s. The ribbon is fully crystallized after annealing at 500°C for only 10s and shows good superelasticity and shape memory effect. The properties of the ribbon reached a stable state when the annealing time is around 60s. The present research shows that annealing at 500°C for short duration is important to achieve good properties from initially amorphous melt-spun ribbon. The reason is discussed based on the evolution of the microstructures.
