摘要
Abstract
The Ti-50.9at% Ni shape memory alloy thin fires are deposited on pure Si substrate by DC-magnetron sputtering. The films were then annealed at different temperatures for 30 min. The effect of annealing temperature on the microstrueture, transformation behavior and residual stress of the fires was characterized by differential scanning calorimeter, X-ray diffraction and transmission electron microscopy. The results show that the deposited films were amorphous and range of crystallization temperature was 430℃-535℃ with appearance of the precipitate phase （Ni4Ti3）. As the annealing temperature increased, all of the Rs, Af and Ms increased as well while the residual stress is gradually decreased.关键词
