摘要
Fe3Si基合金由于有序相的出现而导致的很强的环境脆性和本征脆性,使其难以进行机械加工和热加工.依据挤压能够提高材料塑性的原理,系统地研究了Fe3Si基合金的温挤压工艺.利用温挤压开坯技术,实现Fe3Si基合金的低温轧制.通过实验得出了Fe3Si基合金温挤压工艺的各项参数.
Strong environment brittleness and intrinsic brittleness of Fe-Si system alloys caused by ordered phases result in difficulties in machining and heat machining. Based on the principle of increasing the plasticity of materials by extruding, the warm extrusion process of Fe-Si system alloys was investigated systematically. The warm extrusion blooming technology was used to realize the low temperature rolling of an Fe3Si-base alloy. All parameters for the extrusion process were gained by experiment.
