摘要： A conveying device with peristaltic movement includes a flexible transport tube and a two-way shape memory alloy. The two-way shape memory alloy is mounted on the surface of the transport tube. When the two-way shape memory alloy is electrically conducted and heated, the cross-sectional area of transport path in the flexible transport tube contracts by the contractive force resulting therefrom. When electrically conducting and heating the two-way shape memory alloy is terminated, the original cross-sectional area of transport path in the flexible transport tube is restored by the recovery force thereof. The position of the flexible transport tube at which the contraction and the restoration are applied to is sequentially moved in a predetermined direction by a temperature controlling device, so as to convey an object within the flexible transport tube in the predetermined direction.

摘要： An improved guiding member for use within a body lumen having a unique combination of superelastic characteristics. The superelastic alloy material has a composition consisting of about 30% to about 52% (atomic) titanium, and about 38% to 52% nickel and may have one or more elements selected from the group consisting of iron, cobalt, platinum, palladium, vanadium, copper, zirconium, hafnium and niobium. The alloy material is subjected to thermomechanical processing which includes a final cold working of about 10 to about 75% and then a heat treatment at a temperature between about 450.degree. and about 600.degree. C. and preferably about 475.degree. to about 550.degree. C. Before the heat treatment the cold worked alloy material is preferably subjected to mechanical straightening. The alloy material is preferably subjected to stresses equal to about 5 to about 50% of the room temperature ultimate yield stress of the material during the thermal treatment. The guiding member using such improved material exhibits a stress-induced austenite-to-martensite phase transformation at an exceptionally high constant yield strength of over 90 ksi for solid members and over 70 ksi for tubular members with a broad recoverable strain of at least about 4% during the phase transformation. An essentially whip free product is obtained.

摘要： A metal matrix composite reinforced with shape memory alloy is disclosed ch is formed by blending metal particles and shape memory alloy particles to form a homogeneous powder blend, and consolidating the powder blend to form a unitary mass. The unitary mass is then plastically deformed such as by extrusion in the presence of heat so as to cause an elongation thereof, whereby the metal particles form a matrix and the shape memory alloy partices align in the direction of elongation of the unitary mass. The composite can be used in structural applications and will exhibit shape memory characteristics.

摘要： A process for making Type 60 Nitinol with shape memory effect from hot-worked material, such as hot rolled Type 60 Nitinol sheet or plate, includes heat treatment to a temperature of 600° C.–800° C. and holding the material at that temperature until the temperature has equalized throughout, and then heat soaking at that temperature for about 15 minutes. The material is then quenched immediately from that temperature, to a temperature below 300° C. This heat treatment produces Type 60 Nitinol in a condition denoted “ultraelastic”. Ultraelastic Type 60 Nitinol has a shape memory characteristic having a very low transition temperature. The transition temperature can be tailored within a wide temperature range by the temperature of the initial heat treatment and subsequent rate of cooling.
