“…The sticking is more likely to occur at the temperature range in which the rolled steel is soft with low tensile strength, and also little amount of oxide scale is on the surface. The work of Jin et al [6] indicated that there was a critical oxide scale thickness (about 3.0 µm) in the suppression of the sticking phenomenon. The thicker oxide scale is desirable.…”

“…15b, will increase the possibility of scratching the roll surface, and the lower the temperature the harder the oxide scale. Once there are more scratches on the roll surface, the sticking will become significant because these scratches might provide the nucleation site for the sticking particles, and the sticking particle grows more and more on the site as the rolling processes [6]. At a higher temperature, the thicker oxide scale (Fig.…”

“…Sticking refers to a phenomenon occurring in hot rolling process in which fragments of a rolled material are detached and get stuck onto a work roll surface, deteriorating not only the surface quality of the product, but also the rolls, which will result in shorter intervals of roll replacement or grinding [4,5]. A sticking occurrence was more sensitive for the steels containing more chromium [6]. Fig.…”

“…This is caused by abrasion during the contact of the roll and the strip. Jin et al [6,7] and Ha et al [1,8,9] have intensively investigated the sticking mechanism. For the rolled materials, the tensile strength and the oxidation behaviour of the materials affect the sticking in hot rolling.…”

Severe sticking occurs in the hot rolling of ferritic stainless steel B445J1M. The characteristics of the oxide scale on the steel in hot rolling are associated with this phenomenon. The tensile failure of the oxide scale formed on the steel B445J1M was investigated by using a Gleeble 3500 thermo-mechanical simulator over temperature range from 1000 to 1150°C in humid air. Two passes hot rolling were carried out on a 2-high Hille 100 experimental rolling mill. The results show that the temperature is a significant factor for the formed thickness of the oxide scale and its failure in tensile stress. On the specimen before hot rolling, irregular spinels are extruded from the surface of a thin oxide scale with Cr2O3 as its main component, which are hard and brittle at lower rolling temperature.

Li metal batteries have been widely expected to break the energy‐density limits of current Li‐ion batteries, showing impressive prospects for the next‐generation electrochemical energy storage system. Although much progress has been achieved in stabilizing the Li metal anode, the current Li electrode still lacks efficiency and safety. Moreover, a practical Li metal battery requires a thickness‐controllable Li electrode to maximally balance the energy density and stability. However, due to the stickiness and fragile nature of Li metal, manufacturing Li ingot into thin electrodes from conventional approaches has historically remained challenging, limiting the sufficient utilization of energy density in Li metal batteries. Aiming at the practical application of Li metal anode, the current issues and their initiation mechanism are comprehensively summarized from the stability and processability perspectives. Recent advances in robust and ultra‐thin Li metal anode are outlined from methodology innovation to provide an overall insight. Finally, challenges and prospective developments regarding this burgeoning field are critically discussed to afford future outlooks. With the development of advanced processing and modification technology, we are optimistic that a truly great leap will be achieved in the foreseeable future toward the industrial application of Li metal batteries.

In this paper, the isothermal oxidation of the indefinite chill (IC) roll is investigated by using a thermogravimetric analyzer (TGA) from 550 to 700 °C under dry and humid atmospheres. It is found that the oxidation kinetics follow a linear trend and the oxide scale consists of two layers after the oxidation in dry air but three layers in humid air above 600 °C. In dry air, the graphite is covered by the oxide scale above 650 °C. The water vapor accelerates the oxidation of the matrix and the graphite. The graphite is covered by the extension of the oxide scale above 600 °C in humid air. The as‐treated samples are examined with SEM and XRD, while the kinetics is based on TGA results.
