Abstract
The present invention provides a kind of high-temperature resistant alloy with low nickel-cobalt content. Said alloy has good deformability, high toughness and high high-temperature resistance. Said alloy contains 5-7 main elements, and is made up by using CoCrFeNi as basis and adding at least one of Al, Mo and Ti as main element through a certain preparation process. Besides, said invention also provides the concrete steps of said preparation process.
