Abstract—

The effect of a magnetic field on the deformation characteristics of a diamagnetic material Grade C2 lead (99.98% purity) is studied. Initially, the creep process and the microhardness were studied in the initial state, then such studies were carried out using d.c. magnetic fields with inductions 0.3, 0.4, and 0.5 T in the process of creep of the samples and magnetic processing of the samples to study the dynamics of the microhardness and the plasticity parameter. The results of creep tests indicate the presence of an ambiguous nature of the influence of the magnetic field on the creep rate; a change in the sign of the effect was found with an increase in the value of the magnetic field induction to 0.4 and 0.5 T. Also, the alternating nature of the influence of the magnetic field was also established in the study of the microhardness. In addition, it is found that the use of a magnetic field in the process of sample creep quantitatively influences the percentage of the relative residual elongation of the sample (it decreases as compared to the initial one with an increase in the magnetic field induction) upon destruction and the creep process time (increases compared to the initial one at increase in the magnetic field induction). A rational exposure time in a magnetic field during the microhardness tests was revealed, it was found that the maximum effect of a magnetic field manifests itself at exposures for 1 h, in connection with which two exposure modes in this range (0.25 and 0.5 h) are studied.

0.5T感应磁场对铅变形特性动力学的影响

摘要-

研究了磁场对抗磁性材料 C2 级铅（纯度 99.98%）变形特性的影响。最初是在初始状态下研究蠕变过程和显微硬度，然后利用感应强度为0.3、0.4和0.5 T的直流磁场对样品的蠕变过程和样品的磁处理进行研究。显微硬度和塑性参数的动力学。蠕变试验的结果表明磁场对蠕变速率的影响存在模糊性；随着磁场感应值增加到 0.4 和 0.5 T，效应的符号发生变化。此外，在显微硬度的研究中还建立了磁场影响的交替性质。此外，还发现在样品蠕变过程中磁场的使用定量地影响了样品的相对残余伸长率（与初始相对残余伸长率相比，随着磁场感应的增加而减小）。破坏和蠕变过程时间（与初始相比，随着磁场感应的增加而增加）。揭示了显微硬度测试期间在磁场中的合理暴露时间，发现磁场的最大效应在暴露 1 小时时表现出来，与该范围内的两种暴露模式（0.25 和 0.5 小时）相关被研究。
