Direct chill casting of aluminium alloys under electromagnetic interaction by permanent magnet assembly

2018

Direct chill casting is one of the methods used in industry to obtain good microstructure and properties of aluminium alloys. Nevertheless, for some alloys grain structure is not optimal. In this study, we offer the use of electromagnetic interaction to modify melt convection near the solidification interface. Solidification under various electromagnetic interactions has been widely studied, but usually at low solidification velocity and high thermal gradient. This type of interaction may succeed fragmentation of dendrite arms and transport of solidification nuclei thus leading to improved material structure and properties.

The Two-Nucleon System beyond the Pion Threshold

2003

A model is developed for the hadronic and electromagnetic interaction in the two-nucleon system above pion threshold in the framework of meson, nucleon and Δ degrees of freedom. It is based on time-ordered perturbation theory and includes full meson retardation in potentials and exchange currents as well as loop contributions to the nucleonic one-body current. Results for some selected processes are discussed.

A phenomenological quark current for the study of the polarized structure function of the nucleon

1995

In the context of the quark model, a phenomenological expression for the electromagnetic interaction is derived in order to study the polarized structure function of the nucleon. The DHG value without hyperfine corrections and the asymptotic behaviour are reproduced.
