摘要
分析了脉冲磁场、脉冲电场、脉冲电磁处理对Ti-Al-Mo-Zr-Si合金组织、位错和硬度的影响。结果表明:采用脉冲电磁处理方法可使合金中的β相转变成α相。合金经脉冲电磁处理后,合金中的位错密度呈现总体降低的变化趋势,同时缠结的位错数量也明显减少。在钛合金的基体中存在众多α相。对材料进行电磁场作用后其基体结构并没有出现显著变化,α-Ti的轴比都出现了明显变大的现象;并且采用脉冲电磁方法处理后的α-Ti轴比达到了最大值。合金经电磁场作用后基体中的初生α相略微上升,导致材料的塑性降低。
The effects of pulsed magnetic field, pulsed electric field and pulsed electromagnetic processing on the microstructure, dislocation and hardness of Ti-Al-Mo-Zr-Si alloy were analyzed. The results show that β phase of the alloy may be converted into α phase by pulsed electromagnetic processing. After pulsed electromagnetic treatment for the alloy, the dislocation density in the alloy generally decreases, and the number of entangled dislocation decreases significantly. There are a large number of α phase in the matrix of titanium alloy. After the action of electromagnetic field, there are no significant change for the structure of the matrix, the axial ratio of α-Ti is significantly increased, and the axial ratio of α-Ti treated by pulsed electromagnetic method reaches the maximum.The primary α phase in the substrate increases slightly after electromagnetic field action, which can lead to the reduction of the plasticity of the material.
