摘　　要：当前,块体非晶合金作为结构材料,其应用不仅面临室温脆性挑战,而且遭遇成形制造瓶颈。解决上述难题已成为近年来材料领域的研究热点与难点之一。近年来发展起来的3D打印技术,已逐渐成为解决块体非晶合金现存困境,实现工程应用的有效途径之一。然而,由于非晶合金具有与晶态材料完全不同的原子结构,3D打印成形中的微观组织演变、缺陷形成与抑制、性能调控等方面的基础理论不同于常规晶态材料,深入剖析上述科学问题对促进块体非晶合金3D打印成形技术的发展具有重要意义。本文依据近年来的国内外研究动态,针对上述问题进行综合分析,并对其发展趋势进行展望。The application of bulk metallic glasses(BMGs) as structural materials not only involves the challenge of room temperature brittleness but also bottlenecks related to formation and manufacturing. Solving these issues has become one of the research hotspots and difficulties in the material field recently. The recently developed 3 D printing technology has gradually become one of the key methods to solve the existing difficulties of BMGs to realize their engineering applications. However, because BMGs have a completely different atomic structure than crystalline materials, the basic theories of material microstructure evolution, defect formation and suppression, and performance adjustment in 3 D printing are completely different. The in-depth analysis of the abovementioned scientific issues is very important for the development of BMG 3 D printing technology. This article is mainly focused on the research trends at home and abroad with a comprehensive analysis of the above problems and looks forward to the development trends of 3 D printing technology.
