曾经报道过加1.0％Zr改善定向铸造高温合金的中温力学性能.我们以前的工作也证明Zr和Hf在铸造镍基高温合金中的作用极为相似,本文进一步研究在上述合金中以Zr代Hf的可能性.
It has also been reported that the addition of 1.0% Zr improves the medium-temperature mechanical properties of oriented cast superalloy.Our previous work also proved that Zr and Hf play very similar roles in the casting of nickel-base superalloy. In this paper, possibility.
