摘　　要：粉末冶金作为制备大块非晶合金的主要方法之一,与快速冷凝相比,该方法可以在更广的合金系、更宽的成分范围内制备出尺寸更大、形状复杂、近净成形的大块非晶合金材料,因此粉末冶金是一种极具前景的大块非晶合金的制备方法。简要介绍了粉末冶金制备大块非晶合金的基本过程,详细阐述了各种成形技术的特点、原理、优缺点以及制备大块非晶合金的研究进展,期望为非晶、纳米晶粉末的致密化研究和制备大块非晶合金提供技术指导。Powder metallurgy as one of main methods of preparing bulk amorphous alloys can produce bulk amorphous samples with larger dimensions, complex shapes and near net shape in wider composition range when compared to rapid solidification, therefore, powder metallurgy is an outstanding potential preparation method of bulk a- morphous alloys. The basic process in the field of preparing bulk amorphous alloys by powder metallurgy is introduced. The eharacteristics, principles, advantages and disadvantages, research progress in forming bulk amorphous alloys by several methods are introduced, so as to provide technical guidance for the study of amorphous, nano-crystalline powder densification and the preparation of bulk amorphous alloys.
