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.

高达 0.5 T 的感应磁场对铅变形动力学特性的影响

摘要研究了磁场对二磁性材料 C2 级铅（纯度 99.98%）变形特性的影响。首先研究了初始状态下的蠕变过程和显微硬度，然后在样品蠕变过程中使用感应电压为 0.3、0.4 和 0.5 T 的直流磁场进行了此类研究，并对样品进行了磁处理，以研究显微硬度和塑性参数的动态变化。蠕变试验结果表明，磁场对蠕变速率的影响具有模糊性；磁场感应值增加到 0.4 和 0.5 T 时，影响的符号发生了变化。此外，研究还发现，在样品蠕变过程中使用磁场会定量影响样品破坏后相对残余伸长率的百分比（与初始百分比相比，磁场感应增加，残余伸长率减少）和蠕变过程时间（与初始百分比相比，磁场感应增加，蠕变过程时间增加）。在显微硬度测试过程中，磁场暴露时间的合理性得到了揭示，发现磁场的最大影响体现在暴露 1 小时时，为此研究了该范围内的两种暴露模式（0.25 和 0.5 小时）。
