Results obtained at the Mariupol Metallurgical Combine with a new technology for reconditioning the steel work rolls of hot-rolling mills are presented. The technology is based on hard-facing of the rolls with strip electrodes made of steels 20Kh4MFB, 15kp, and 08kp. Rolls hard-faced with a composite consisting of alternating strong and ductile layers are shown to have good fracture toughness. The...
Typical features and the difference in specimen fractures are described for rolled plate DWTT specimens manufactured by controlled rolling technology with final deformation in the two-phase γ+α-region, or controlled rolling with final deformation in the γ-region and subsequent accelerated cooling. The question is considered of the effect of the amount of absorbed energy on specimen failure mechanism...
