TL;DR: In this paper, the wear mechanisms of the tempered martensitic X38CrMoV5 steel (AISI H11) under high-temperature and dry-sliding wear were investigated.

TL;DR: In this paper, the interaction between oxides formed on a work roll grade and the coefficient of friction established with a strip steel usually rolled by this roll grade was studied. But the authors focused on the formation and growth of the oxide scale.

TL;DR: In this article, a high temperature pin on disc tribometer is used to measure the friction coefficient and wear of hot working rolls. But the wear and friction behavior of the oxides appearing on the surface of the hot working rolling is not well known.

TL;DR: In this paper, an approach is proposed to assess the coupled effect of oxidation and friction on the overall tribological behaviour at high temperature. But this approach does not aim to reproduce strictly rolling conditions, but only to analyse the chemical and mechanical response of roll grades regarding thermal and mechanical stresses involved in hot rolling.

TL;DR: In this article, an experimental study was conducted on a low-carbon steel sheet and a X160CrMoV12 steel die radius and revealed that the die radius surface was degraded by ploughing and transfer mechanisms.
