摘要
非晶复合材料具有高强度力学性能的同时又表现为宏观脆性,而半固态工艺可以提高非晶复合材料的宏观塑性。主要综述了非晶复合材料的发展历程和分类,简要介绍了半固态成形工艺。重点介绍了半固态成形技术制备半固态非晶复合材料坯料或浆料的主要方法和具体工艺,同时追踪了利用半固态成形技术(锻造成形、铸造成形、轧制成形)制备的非晶复合材料产品的最新研究,进而介绍了半固态等温热处理对非晶复合材料微观组织的影响规律。最后对比了半固态流变成形和触变成形的优缺点,展望了流变成形技术在非晶复合材料领域的推进和应用。
Amorphous composites have high-strength mechanical properties while exhibiting macro-brittleness. However, semi-solid technology can improve the macro-plasticity of amorphous composite materials. This paper mainly reviewed the development and classification of amorphous composites, and briefly introduced the semi-solid forming process. The main methods and specific processes of semi-solid forming technology in the preparation of semi-solid amorphous composite ingot or slurry were mainly introduced. At the same time, the latest research on amorphous composite products prepared by semi-solid forming technology(forging forming, casting forming, rolling forming) was also tracked. Furthermore, the effect of semi-solid isothermal heat treatment on microstructure of amorphous composites was introduced. Finally, the advantages and disadvantages of semi-solid rheoforming and thixoforming were compared, and the advance and application of rheoforming technology in the field of amorphous composites were forecasted.
