Shape-memory NiTi–Nb foams
A new powder metallurgy technique for creating porous NiTi is demonstrated, combining liquid phase sintering of prealloyed NiTi powders by Nb additions and pore creation by NaCl space-holders. The resulting foams exhibit well-densified NiTi–Nb walls surrounding interconnected pores created by the space-holder, with controlled fraction, size, and shape. Only small amounts of Nb (3 at.%) are need...
متن کاملShape Memory Polymer Foams for Biomedical Devices
Developed in last decade, the shape memory polymers (SMP) have been gaining widespread attention for new product innovation. They are lightweight, have a high strain/shape recovery ability, are easy to process, and required properties can be tailored for a variety of applications. Recently a number of medical applications have been considered and investigated for polyurethane-based SMP material...
متن کاملShape Memory Behavior of PET Foams
Shape memory properties of PET (polyethylene-terephthalate) foams have been evaluated for two different foam densities. Samples were subjected to multiple memory-recovery cycles along three different directions to measure the effect of foam anisotropy on static mechanical and shape memory properties. The memory cycle was performed by uniaxial compression tests at room temperature. Despite these...
متن کاملA Shape Memory Polymer with Improved Shape Recovery
Thermally actuated shape memory polymers (SMPs) interest, both academically and industrially, due to their ability to memorize a permanent shape that is set during processing and a temporary shape that is later programmed by manipulation above a critical temperature, either Tg or Tm. However, the thermal triggering process for SMPs is usually retarded compared to that of shape memory alloys, be...
متن کاملPreparation and characterization of triple shape memory composite foams.
Foams prepared from shape memory polymers (SMPs) offer the potential for low density materials that can be triggered to deploy with a large volume change, unlike their solid counterparts that do so at near-constant volume. While examples of shape memory foams have been reported in the past, they have been limited to dual SMPs: those polymers featuring one switching transition between an arbitra...
