MARTENSITIC TRANSFORMATION BEHAVIORS OF TiNi SHAPE MEMORY ALLOY FIBER/CEMENT COMPOSITE

The martensitic transformation behaviors of TiNi shape memory alloy-cement composite are explored. The DSC results indicate that the reverse transformation temperature of the remained martensite increases due to the constraint of the cement matrix. In the beginning of the reverse martensitic transformation, the average reverse transformation ratio is larger. Above the finish temperature of the endothermic peak in the DSC heating curve of the cement composite sample, the reverse transformation of the remained martensite is still undergoing slowly.
