Abstract
Mechanical tests of commercially pure lead grade C2 were carried out, cylindrical samples of lead were destroyed in the process of creep with a constant tensile force. The tests were carried out initially without the inclusion of a magnetic field during deformation, then with the inclusion of a magnetic field with an induction of 0.5 T. Based on the data obtained, characteristic curves of the creep process were constructed. A change in the nature of the curve is revealed. At the discovered linear stage of the process, the creep rate was calculated. A decrease in the creep rate is shown compared to the process without the action of an external magnetic field. The duration of the creep process is analyzed depending on the induction and the percentage of residual relative elongation of the samples. Analysis of the fractograms showed a difference in the morphology of fractures in the studied samples. With the use of a magnetic field during the destruction of the sample, the number of pits on the surface decreased, the fibrous zone increased, and the fracture morphology changed.
期刊介绍：
Technical Physics Letters is a companion journal to Technical Physics and offers rapid publication of developments in theoretical and experimental physics with potential technological applications. Recent emphasis has included many papers on gas lasers and on lasing in semiconductors, as well as many reports on high Tc superconductivity. The excellent coverage of plasma physics seen in the parent journal, Technical Physics, is also present here with quick communication of developments in theoretical and experimental work in all fields with probable technical applications. Topics covered are basic and applied physics; plasma physics; solid state physics; physical electronics; accelerators; microwave electron devices; holography.
