The shape memorizing function of the EVA plastic had been studied,the results indicated that the EVA plastics can be cross linked with DCP ,and the properly cross linked EVA will have a good shape memory properties, which shape recovering rate and shape fixed rate can be 95% or more.
Comparing to the liner shape memory polyurethane, The shape recovering temperature of the crosslinked polyurethane was randomly controlled and the crosslinked polyurethane has completely shape memory behavior.
Basing on the experimental data of all kinds of references about TiNiPd alloys,the relationship between the transformation temperatures and the content of Ti50Ni50- x Pd x alloy is presented,the transformation sequences are concluded and a concise analysis of the factors which change the alloy's shape memory behavior is given in this paper.
Therefore, this kind of polyurethane can be used for implanted medical devices with shape memory requirements.
A quantitative index martensite fraction was used to describe the phase transformation degree of shape memory alloy (SMA).
A hydroxyapatite (HA)/collagen (COL) composite coating on NiTi shape memory alloy (SMA) was prepared by eletrochemical deposition (ELD) in modified simulated body fluid (MSBF).
Effects of severe deformation and heat treatment on the transformation behaviors of explosively welded duplex TiNi/TiNi shape memory alloys (SMAs) were investigated by the differential scanning calorimeter (DSC).
