The activation parameters of the Shape memory effect of polylactide were reduced by creating a polymer-polymer composite material based on it. The improved material was used to obtain porous scaffolds by electro-spinning, the shape memory effect and the piezoelectric effect were studied for these scaffolds.

The Matrix

In this paper, the TiNi fiber reinforced / PC composite material was developed, and then control of the fatigue crack growth due to the shape memory effect was studied. Enhancement of mechanical properties and resistance of deformation of the TiNi fiber reinforced / PC composite were investigated by fatigue experiments. The fatigue behavior and crack propagation were in-situ observed with a SEM servo-pulser (fatigue testing instrument with scanning electron microscope) while increasing temperature. As the results, the fatigue life was improved, and the effectiveness of fatigue resistance was confirmed. The shape memory effect and expansion behavior of the matrix caused by temperature increasing examined the effect of the fatigue crack propagation control. It was verified that the control of fatigue crack growth is attributed to the compressive stress field in the matrix due to shrinkage of the TiNi fibers above austenitic finishing temperature (Af).

Imperfect Shape

Intermetallic compounds of ZrNi-ZrCo cross-section undergo martensitic phase transformation, which is accompanied by the imperfect shape memory effect at elevated temperatures. Martensitic transformation is also taking place in one of the constituents for the in-situ composites of ZrCo-Zr2Co-Zr2Ni-ZrNi region. High temperature shape memory behavior of Zr-Ni-Co composite material shows improvement in shape recovery comparing to quasibinary intermetallic compounds of ZrNi-ZrCo cross-section.

Shear Transformation

An interest in NiTi alloys with near stoichiometric composition (55 NiTi) has intensified since they were found to exhibit a unique mechanical shape memory effect at the Naval Ordnance Laboratory some twelve years ago (thus refered to as NITINOL alloys). Since then, the microstructural mechanisms associated with the shape memory effect have been investigated and several interesting engineering applications have appeared.The shape memory effect implies that the alloy deformed from an initial shape will spontaneously return to that initial state upon heating. This behavior is reported to be related to a diffusionless shear transformation which takes place between similar but slightly different CsCl type structures.
