Effect of the Temperature of Hot Rolling on Formation of Microdiscontinuities on Nonmetallic Inclusions in Steel ShKh15SG

Formation of micropores near nonmetallic inclusions under fatigue fracture of a bearing steel is considered. Dependences of pore formation on the temperature of hot rolling of the steel and relations between the number of pores and the deformation temperature are presented. Recommendations are given...

Beschreibung
Zusammenfassung:	Formation of micropores near nonmetallic inclusions under fatigue fracture of a bearing steel is considered. Dependences of pore formation on the temperature of hot rolling of the steel and relations between the number of pores and the deformation temperature are presented. Recommendations are given on the deformation temperature ranges.
