    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： A free-cutting Ni-base heat-resistant alloy excellent in the high-temperature strength and corrosion resistance was proposed. The alloy contains Ni as a major component, 0.01 to 0.3 wt % of C and 14 to 35 wt % of Cr, and further contains at least one element selected from Ti, Zr and Hf in a total amount of 0.1 to 6 wt %, and S in an amount of 0.015 to 0.5 wt %. The alloy has dispersed in the matrix thereof a machinability improving compound phase, where such phase contains any one of Ti, Zr and Hf as a major constituent of the metal elements, essentially contains C and either S or Se as a binding component for such metal elements. The alloy also satisfies the relations of WTi+0.53WZr+0.27WHf>2WC+0.75WS and WC>0.37WS, where WTi represents Ti content (wt %), WZr represents Zr content (wt %), WHf represents Hf content (wt %), WC represents C content (wt %) and WS represents S content (wt %). This successfully suppresses the amount of free S residing in the alloy, which results in an improved machinability while preventing the hot workability from being degraded.
