With two pilot plants in operation, the Direct Strip Casting (DSC) technology has reached a state from which it can be concluded that a DSC production process is feasible. The core of the process consists of a caster in which liquid steel is fed on a

Free oscillations of the keyhole in penetration laser beam welding are studied theoretically with regard to characteristic frequencies, damping rates and stability at large amplitudes. The normal modes form a discrete set which may be characterized b

The heat conduction model of a cylinder-type source in laser keyhole welding is extended to a time-modulated laser beam with a prescribed energy flux density instead of a prescribed temperature at the wall of the cylinder. A new non-dimensional param

The stability of a cylindrical keyhole is investigated using the energy and pressure balance. Non-equilibrium evaporation from the keyhole surface, surface tension, hydrostatic and hydrodynamic pressure in the melt as well as heat conduction into the

The conjecture which explains the humping phenomenon in terms of Marangoni convection is discussed and rejected. Instead, Rayleigh's theory of the instability of a free liquid cylinder due to surface tension is applied. The width-to-length ratio of t

On‐line non‐destructive assessment of steel strip properties is a subject of growing interest amongst European manufacturers, as it provides information all along the products length, without slowing down the production. Arcelor, Salzgitter and T

A simple quasi one-dimensional self-consistent model of the keyhole in penetration laser welding has been given previously. By considering the equation of heat conduction and the pressure balance at the keyhole wall, the radius of the keyhole was obt

Mechanical-technological quantities are used to characterize steel and its quality. Here in particular tensile strength, yield strength and anisotropy values are considered. To measure these quantities the magnetoinductive Non Linear Harmonics Analys

Transferrin (Tf) mRNA was recently demonstrated in rat and mouse placental tissue. Rat placental cells were shown to secrete transferrin. The cell type with which Tf mRNA was associated was not investigated. We therefore studied the ability of immuno
