Effects of Rolling Parameters on Work-roll Thermal Crown in Hot-strip Rolling
DEStech Transactions on Computer Science and Engineering, 2017 The thermal crown variations of work-roll during hot-strip rolling are analyzed by a finite element model. To further study of thermal crown of workroll, the effects of different parameters are taken into account such as rolling speed, interval time of rolling and cooling water flow rate.

Phosphorus Segregation in Meta-Rapidly Solidified Carbon Steels
High Temperature Materials and Processes, 2017 Twin-roll strip casters for near-net-shape manufacture of steels have received increased attention in the steel industry. Although negative segregation of phosphorus occurred in twin-roll strip casting (TRSC) steels in our prior work, its mechanism is ...

Inflation in no-scale supergravity
, 2015 $R+R^2$ Supergravity is known to be equivalent to standard Supergravity coupled to two chiral supermultiples with a no-scale K\"ahler potential. Within this framework, that can accomodate vanishing vacuum energy and spontaneous supersymmetry breaking, we
