Warm extrusion process of Fe-Si system alloys

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.
