摘要
开发了一种碳化物强化锻造镍基超级合金。该合金依靠碳化物分散强化。在 1100-1200 °C 等温压缩试验中，均质合金显示出较高的变形塑性，并可通过再结晶改善显微组织。碳化物强化锻造合金在 850-900 ℃ 下时效后，显示出优异的抗拉强度。在相同条件下，碳化物比γ′具有更高的显微组织稳定性。本文报告的结果反映了经济型镍基锻造超级合金在 800 ℃ 以上使用的潜力。
Potential of carbide strengthened economical wrought nickel-based alloy for high temperature
A carbide strengthened wrought Ni-based superalloy is developed. The alloy depends on carbide dispersion strengthening. A high deformation plasticity in homogeneous alloy is shown in the 1100–1200 °C isothermal compression test and the improvement of microstructure can be achieved by recrystallization. After aging at 850–900 °C, the carbide strengthened wrought alloy appears excellent tensile strength. Carbide exists higher microstructure stability than γ′ in the same condition. The herein reported results reflect the potential of the economical wrought Ni-based superalloy to service above 800 °C.
