Abstract
It is shown on the basis of developing hydrogen brittleness ideas that this parameter is influenced mainly by flawed cavities formed at the ferrite-cementite phase boundary and not by crystal lattice defects and other discontinuities of metal. The influence of antiflaking heat treatment (AFHT) on hydrogen flawed cavity formation is established as well as nonlinear changes in cold resistance at the aging of metal not exposed to AFHT. The influence of microstructural and phase composition and phase formation pattern on the cold resistance of steel is considered. The most pronounced negative effect on cold resistance is produced by all the phases formed by shearing. The influence of the final temperature of the finishing rolling stage on cold resistance is substantiated depending on the critical temperature interval.
期刊介绍：
Steel in Translation is a journal that represents a selection of translated articles from two Russian metallurgical journals: Stal’ and Izvestiya Vysshikh Uchebnykh Zavedenii. Chernaya Metallurgiya . Steel in Translation covers new developments in blast furnaces, steelmaking, rolled products, tubes, and metal manufacturing as well as unconventional methods of metallurgy and conservation of resources. Papers in materials science and relevant commercial applications make up a considerable portion of the journal’s contents. There is an emphasis on metal quality and cost effectiveness of metal production and treatment.
