研究了新型镍钴合金的高温蠕变行为。结果表明,当蠕变温度为625℃时,其显微组织主要是扩展位错层;当蠕变温度为700℃时,其显微组织主要是扩展位错层和变形微孪晶;当蠕变温度为800℃时,其显微组织主要为粗大的γ′相。
The creep behavior of the new Ni-Co alloys at high temperature was studied. The results show that when the creep temperature is 625 ℃, the microstructure is mainly extended dislocation layer. When the creep temperature is 700 ℃, the microstructure is mainly extended dislocation layer and deformation micro-twins. When the creep temperature is 625 ℃, When the temperature is 800 ℃, the microstructure is mainly coarse γ ’phase.
