摘要： The present invention relates to a Ni base alloy having sufficient strength at high temperatures and high corrosion resistance at high temperatures in a high-temperature composite corrosive environment in which chlorination or sulfidation occurs simultaneously with high-temperature oxidation, without excessive cooling or surface protection. According to the present invention, a Ni base alloy having high-temperature strength and corrosion resistance includes Cr in a range of from 25 to 40 weight %, Al in a range of from 1.5 to 2.5 weight %, C in a range of from 0.1 to 0.5 weight %, W of 15 weight % or less, Mn of 2.0 weight % or less, Si in a range of from 0.3 to 6 weight %, Fe of 5% or less, and Ni of rest except inevitable impurities. When strength at high temperatures is allowed to be small, W is in a range of from 0 to 8%, and Si is in a range of from 0.3 to 1% or from 1 to 6%. In order to enhance strength at high temperatures, W is in a range of from 8 to 15, and Si is in a range of from 0.3 to 1% or from 1 to 6%.

摘要： Provided is free cutting alloy excellent in machinability, preserving various characteristics as alloy. The free cutting alloy contains: one or more of Ti and Zr as a metal element component; and C being an indispensable element as a bonding component with the metal element component, wherein a (Ti,Zr) based compound including one or more of S, Se and Te is formed in a matrix metal phase. The free cutting alloy is more excellent in machinability, preserving various characteristics as alloy at similar levels to a conventional case. The effect is especially conspicuous, for example, when a compound expressed in a chemical form of (Ti,Zr)4C2(S,Se,Te)2 as the (Ti,Zr) based compound is formed at least in a dispersed state in the alloy structure.
