摘要： An iridium-based alloy which has L12-type intermetallic compounds dispersedly precipitated therein and has a basic composition including, in terms of mass proportion, 0.1 to 9.0% Al, 1.0 to 45% W, and Ir as the remainder. The component system containing 0.1 to 1.5% Al has L12-type intermetallic compounds dispersedly precipitated therein. The component system containing 1.5 to 9.0%, excluding 1.5%, Al has L12-type and B2-type intermetallic compounds dispersedly precipitated therein. Part of the Ir may be replaced with an element (X) (Co, Ni, Fe, Cr, Rh, Re, Pd, Pt, or Ru) and part of the Al and W may be replaced with an element (Z) (Ni, Ti, Nb, Zr, V, Ta, Hf, or Mo). The iridium-based alloy, which contains L12-type intermetallic compounds [1r3(Al,W) and [(Ir, X)3(Al, W, Z)] dispersedly precipitated therein, has a high melting point. The lattice constant mismatch between the L12-type intermetallic compounds, i.e., [Ir3 (Al, W)] and [(Ir, X)3(Al, W, Z)], and the matrix is small and, hence, the iridium-based alloy is excellent in high-temperature strength and structural stability.
摘要翻译：具有分散析出的L12型金属间化合物的铱系合金，其基本组成按质量比计含有0.1〜9.0％的Al，1.0〜45％的W，其余为Ir。含有0.1〜1.5％Al的成分体系分散析出L12型金属间化合物。含有1.5〜9.0％（不包括1.5％）Al的组分体系中分散析出了L12型和B2型金属间化合物。可以用元素（X）（Co，Ni，Fe，Cr，Rh，Re，Pd，Pt或Ru）代替Ir的一部分，Al和W的一部分可以被元素（Z） Ni，Ti，Nb，Zr，V，Ta，Hf或Mo）。含有在其中分散沉淀的L12型金属间化合物[1r3（Al，W）和[（Ir，X）3（Al，W，Z）]的铱系合金具有高熔点。 L12型金属间化合物即[Ir 3（Al，W）]和[（Ir，X）3（Al，W，Z）]和基体之间的晶格常数不匹配很小，因此铱的合金具有优异的高温强度和结构稳定性。

摘要： A guide wire includes a distal core member made of a ferrous alloy which has shape memory properties and superelasticity. The ferrous alloy preferably includes substantially two phases, and has a difference of 100° C or less between an Af point and an Ms point in a thermal hysteresis of martensitic transformation and reverse transformation. The guide wire may include a proximal core member made of an iron-containing alloy and having a higher modulus of elasticity than the distal core member. The two core members may be joined together by welding to form a core of the guide wire.
