    摘要:

    尋求可打印金屬材料的研究至關(guān)重要。近年來，多種可打印性良好的材料已被發(fā)掘出來，如Ti-6Al-4V、FeMnCoCrNi、不銹鋼及一些難熔高熵合金。盡管已經(jīng)獲得了諸多可喜結(jié)果，增材制造難熔高熵合金依然發(fā)展緩慢。由于難熔高熵合金的優(yōu)越高溫性能，復(fù)雜成形的需求也日漸高漲。本文主要介紹了增材制造難熔高熵合金的一些研究進展，綜述了有關(guān)難熔高熵合金激光增材制造、電子束增材制造和絲材增材制造技術(shù)，并為后續(xù)研究工作提供參考。此外，本文也系統(tǒng)地討論了有關(guān)增材制造難熔高熵合金面臨的機遇和挑戰(zhàn)。

    Abstract:

    Searching for printable metallic materials is of great importance. In recent years, several kinds of printable alloys have been researched, such as Ti-6Al-4V, FeMnCoCrNi, stainless steels, and some refractory high-entropy alloys (RHEAs). In spite of these delightful results, the development in additive manufacturing of RHEAs is proceeding slowly. Because of the excellent behavior of RHEAs at high temperatures, more requirements are proposed for the complex shape forming. This review primarily introduced the recent studies on additive manufacturing of RHEAs. The laser beam-based, electron beam-based, and wire-based additive manufacturing techniques for fabrication of RHEAs were summarized. In addition, the opportunities and challenges of the current development of RHEAs fabricated by additive manufacturing were discussed.
