The paper studies the structure and phase composition of steel 0.12C–1Cr–1Mo–1V–Fe (grade DIN 14MoV63) after a long-term operation using the transmission electron microscopyю Investigated are the nontreated specimen (not subjected to operation) and specimens after a long-term operation with and without fracture. The phase composition and morphology of the steel structure are determined for each specimen. It is found that the steel servicing leads to the destruction of lamellar perlite, intensive fragmentation of ferrite, redistribution of the carbide component and elastic distortion of the crystal lattice.

使用寿命对DIN 14MoV63钢结构和相组成的影响

本文使用透射电子显微镜研究了长期运行后的0.12C–1Cr–1Mo–1V–1Fe–钢（DIN 14MoV63级）的结构和相组成。研究了未经处理的试样（未经操作）和经过热处理的试样。长期手术，有无骨折。确定每个样品的钢结构的相组成和形态。已发现，进行钢材维修会导致层状珍珠岩的破坏，铁素体的强烈破碎，碳化物成分的重新分布以及晶格的弹性变形。
