摘要:

鎳基多晶高溫合金具有出色的抗蠕變性能，廣泛應用于航空航天、能源電力等領域。隨著工業技術的發展，對鎳基多晶高溫合金蠕變性能的要求也變得越來越嚴苛。為了改善其蠕變性能，研究人員進行了大量工作，重點研究了合金元素對鎳基多晶高溫合金蠕變性能的影響，以期通過添加合金元素來實現最大限度的抗蠕變性能提升。以鎳基多晶高溫合金為主要闡述對象，分別綜述了合金元素的添加對碳化物相、晶界、γ基體相和γ′沉淀相的影響，探討了不同組織結構下合金蠕變變形機理，為鎳基多晶高溫合金的設計、制備及其抗蠕變性能的提升提供一定的理論依據和科學指導。

Abstract:

Ni-base crystalline superalloy has excellent creep resistance, and is widely used in aerospace engineering, energy and power generation and other industrial fields. With the development of industry technology, the requirements for creep properties of Ni-base crystalline superalloy have become more and more stringent. Researchers have carried out a lot of work, focusing on the effect of alloying elements on the creep properties, in order to achieve maximum creep resistance improvement by adding alloying elements. The effect of alloying elements on carbide phase, grain boundary, γ matrix phase and γ′ precipitation phase is reviewed in this paper, providing some scientific guidance for the design, preparation and creep properties improvement of Ni-base crystalline superalloys in the future.
