    摘要:

    增材制造作為一種先進(jìn)的數(shù)字化制造技術(shù),廣泛應(yīng)用于高溫合金制備研究中。介紹了增材制造高溫合金的微觀組織基礎(chǔ)上,梳理增材制造過(guò)程中的氣孔種類(lèi)及特征,回顧了裂紋種類(lèi)及開(kāi)裂傾向性模型的發(fā)展過(guò)程,綜述數(shù)值模擬技術(shù)在增材制造高溫合金性能優(yōu)化的應(yīng)用,并對(duì)增材制造高溫合金的研究和發(fā)展進(jìn)行了展望。

    Abstract:

    Additive Manufacturing (AM) is an advanced digitalized technology that has been extensively applied in the fabrication of high temperature alloys. This paper reviews the microstructure of high temperature alloys prepared by AM, summarizes the type and features of pores, and categorizes the development of models interpreting the formation of cracks. The application of computational science in the research of preparation of high temperature alloys was also reviewed. Finally, the prospect of AM in the research and development of high temperature alloys was discussed.
