Deformation of oxide scale on steel surface during hot rolling
TL;DR: In this article, a glass powder was sprinkled over a mild steel sheet to suppress further oxidation and separation of the oxide scale from the steel, and electron microscopy revealed that the scale deforms uniformly if the reduction is small.

Formation mechanism of surface scale defects in hot rolling process
TL;DR: In this article, it was found that the scale cracking is predictable using the estimated scale temperature and the ductile-brittle transition temperature of Wustite (FeO), and a methodology to produce hot-rolled steels without surface defects in industrial processes was presented.

High-Speed Rolling of AZ31 Magnesium Alloy Having Different Initial Textures
TL;DR: In this article, the texture formation mechanism during high-strain-rate deformation of AZ31 magnesium alloy samples having different initial textures was analyzed and the main components of the textures after the rolling were the RD-split basal, which consisted of 10°-20° inclining basal poles from the normal direction toward the rolling direction of the sheet.

Investigation of Scale Behaviour during Hot Steel Rolling by Oxide Glass
TL;DR: In this article, the scale deformation on steel surface by oxidation at high temperature was investigated using glass powder to observe the scale as hot-rolled steel sheet was inserted to a furnace at 1273K filled with argon.

Microstructure of Oxide Scale on Hot-Rolled Iron
TL;DR: In this article, the microscopic deformation of oxide scale during hot rolling was investigated using scanning electron microscopy (SEM)/ electron backscatter diffraction (EBSD) technique.
