| 6 | TWO KINDS OF VARIANT IN SHAPE MEMORY MATERIAL显示文摘In shape memory materials,that have been trained to have a two way shape memory effect(TWSM),themartensitic variants are classified into two groups,i.e.,preferentially oriented variants and self-accommodatingvariants.Applied stress may promote or constrain the transition of preferentially oriented variants and so changetransformation temperatures but has no essential effect on self-accommodating variants.According to the pointof view mentioned above,some experimental phenomena during thermocycling of a TWSM device may be ex-plained,such as the absence of synchronization between the plot of resistance change.temperature and the plotof memory strain vs.temperature. | Lin,Guangming Lai,J L Huan,Yuanshi Zhongshan University,Guangzhou 510275,China | 1993 | 中国有色金属学会会刊:英文版1993，3，2： | 0 |
