Applied Physics and Mathematics Annotation << Back Thermal aging effects on of Low-ca rbon low allows steels mechanical properties behavier А.А. Chernobaeva М.А. Skundin The paper presents reviews not numerous papers, concerned the study of thermal aging effects in forging from low-carbon low allows steels. The analysis of data, contained in reviewed papers, has been done to reveal the mechanisms of mechanical properties behavior under thermal aging. Special attention has been paid to data analysis of thermal aging of steel 15Kh2NMFA. Study of surveillance specimens from steel 15Kh2NMFA shown no reasons for hardening changing. The reviewed data shown, that use of Hollomon equation for the recalculation of data from higher temperature thermal aging to lower temperature thermal aging can give not correct assessment of effects. Key words: Thermal aging, yield stress, transition temperature, hardening, embrittlement. Contacts: E-mail: anna.chernobaeva@gmail.com Pp. 03-25.
