Influence of ladle slag oxidability on the cleanliness of ultra low carbon steel
工程科学学报, 2016 Slag oxidability, steel composition and inclusions were analyzed by slag sampling and steel sampling from the BOF endpoint to the tundish for studying the influence of ladle slag oxidability on the cleanliness of ultra low carbon steel.

Functorial CW-approximation [PDF]
, 2015 The usual construction of a CW-approximation is functorial up to homotopy, but it is not functorial. In this note, we construct a functorial CW-approximation.

Characterization of Coarse-Grained Heat-Affected Zones in Al and Ti-Deoxidized Offshore Steels
Metals, 2020 Deterioration of the toughness in heat-affected zones (HAZs) due to the thermal cycles caused by welding is a known problem in offshore steels. Acicular ferrite (AF) in the HAZ is generally considered beneficial regarding the toughness.

Quantum Hall Effect and Quantum Point Contact in Bilayer-Patched Epitaxial Graphene
, 2014 We study an epitaxial graphene monolayer with bilayer inclusions via magnetotransport measurements and scanning gate microscopy at low temperatures. We find that bilayer inclusions can be metallic or insulating depending on the initial and gated carrier ...

Basic theory of nonlinear third-order q-difference equations and inclusions
Mathematical Modelling and Analysis, 2013 We investigate the existence of solutions for boundary value problems of the third-order q-difference equations and inclusions. Our results are based on some standard fixed point theorems.
