Notes:
The influence of the strain-holding conditions on shape recovery and secondary-shapeforming was investigated. The results obtained are summarized as follows. (1) If strain is held atholding temperature Th = Tg+20K in a short time, irrecoverable strain starts to appear at the holdingtime th= 0.5h and strain is not recovered at all at th=8h. In the case of Th = Tg+10K, irrecoverable strainappears in a short holding time if holding strain is large and the rate of secondary-shape forming S is42% at th=8h. (2) If strain of 50% is held at Th = Tg+10K in a long time, strain becomes not to berecovered and S is 93% at th =12h. In the case of Th = Tg, the increasing rate of S increases if th islonger than 40h. If Th is lower than Tg-10K for th= 72h, strain is recovered perfectly by heating andsecondary-shape forming does not appear
