Abstract

Microhardness tests of samples of technically pure lead are carried out without and with exposure to external magnetic fields with inductions of 0.3 T, 0.4 T, and 0.5 T. The dependences of the C2-grade lead surface microhardnesses on the exposure times in a magnetic field are obtained, thus reflecting the influence of the magnetic field on the plastic characteristics of lead. The exposure time at which the maximum effect on microhardness occurs is revealed. Additional microhardness tests are carried out for cases with magnetic fields with inductions of up to 0.3, 0.4, and 0.5 T and exposure times of 0.25, 0.5, and 1 hour. Following the obtained microhardness data, the plasticity parameters of lead samples in their initial state and after exposure are calculated. The dependences of the plasticity parameters on the exposure times are shown. The behavior of the plasticity parameter of lead samples during their exposure to external magnetic field with induction up to 0.5 T is revealed. The percent changes in the values of microhardness depending on the magnetic field induction are shown.

铅在 0.5 T 以下感应外磁场中的显微硬度和塑性参数研究

对技术纯铅样品进行了显微硬度测试，分别在无磁场和暴露于 0.3 T、0.4 T 和 0.5 T 感应外磁场的情况下进行。揭示了对显微硬度产生最大影响的暴露时间。在磁场感应高达 0.3、0.4 和 0.5 T 以及暴露时间为 0.25、0.5 和 1 小时的情况下，还进行了其他显微硬度测试。根据获得的显微硬度数据，计算了铅样品在初始状态和暴露后的塑性参数。图中显示了塑性参数与暴露时间的关系。铅样品暴露在磁感应强度高达 0.5 T 的外磁场中时，其塑性参数的变化情况也一目了然。显示了显微硬度值随磁场感应而变化的百分比。
