研究了脉冲电流对SiCp/2024Al复合材料板材加热性能和热拉深性能的影响。高强度脉冲电流流过片材并产生巨大的焦耳热。研究了加热性能和温度分布以确认工艺参数。在电流密度为 21.7 A/mm2 时，样品温度以 13.5 K/s 的速率达到约 673 K。不锈钢嵌件使温差减少 73.3%。此外，工件成功进行了拉深，并表现出良好的表面质量。尺寸精度达到±0.2毫米以内。
The effect of pulse current on heating performance and thermal deep drawing of SiCp/2024Al composite sheets was studied in this work. The high-intensity pulse current flows through the sheet and generates the tremendous Joule heat. The heating performance and temperature distribution were investigated to confirm process parameters. The temperature of specimen is up to around 673 K at a rate of 13.5 K/s under the current density of 21.7 A/mm2. The stainless steel inserts make temperature difference reduced by 73.3 %. Moreover, the workpiece was successfully deep drawn and exhibited good surface quality. The dimensional accuracy achieved within ±0.2 mm.
