Abstract: An object of the present invention is to develop a shape memory and superelastic alloy that does not contain nickel, and has superelasticity and shape memory properties even if being subjected to heat treatment in spite of high biocompatibility, moreover having high cold workability. The Ti—Nb—Zr base alloy is comprising an alloy composition consisting of 40 to 60 wt % Ti, 18 to 30 wt % Nb, 18 to 30 wt % Zr, and 0.77 to 3.7 wt % at least one metal additional element selected from Al, Sn, In and Ga. The Ti—Nb—Zr base alloy is a practical alloy in which the principal components form a strong and dense oxidation film to exhibit high biocompatibility, and also the alloy has superelasticity and shape memory properties, high cold workability, and high low-temperature properties.

Abstract: A Ti—Zr type alloy manifesting excellent plastic workability at normal temperature fit for the use in general industry, allowing improvement in corrosion resistance fit for the use in medical treatment, offering improved corrosion resistance in an acidic solution, particularly a HCl solution, and having flexibility as evinced by a low Young's modulus on a par with a bone; and a medical appliance such as a guide wire to be directly inserted into a blood vessel of a human body under the X-ray fluoroscopy and a stent retained in a human body for a long time, which are made of the Ti—Zr type alloy are provided. The Ti—Zr type alloy of the present invention consists of 25 to 50% by weight of Ti, 25 to 60% by weight of Zr, 5 to 30% by weight of Nb, and 5 to 40% by weight of Ta, provided that the weight ratio of Zr to Ti be in the range of 0.5 to 1.5 and the weight ratio of Nb to Ta be in the range of 0.125 to 1.5.

Abstract: A conjugated yarn is provided which is capable of preventing a high-tenacity fiber used therein from being ruptured during a weaving or knitting process. The conjugated yarn includes: core yarns each having a high-tenacity fiber and a reinforcing fiber positioned parallel with the high-tenacity fiber for reinforcing the high-tenacity fiber; and a tying yarn bundling the core yarns. Also provided is a fiber reinforced plastic of which the strength and safety are improved by the use of the conjugated yarn.

Abstract: The present invention discloses a method of forming a metallic coating layer utilizing media having high energy which are capable of employing every kind of solid particulate.By employing the media having high energy, metallic powders as coating material are stricken onto the surface of an object to be coated so as to increase gradually the thickness of the metallic coating layer by repeating the aforementioned striking operation. Thus, the component of the metallic coating layer may be mechanically alloyed with the object to be coated.
