The transformation of the steel industry toward more sustainable and efficient production routes requires continuous innovation in remelting technologies such as Vacuum Arc Remelting (VAR) and Electroslag Remelting (ESR). High-performance copper components are essential in this context, as they directly influence process stability, product quality, and resource efficiency. This contribution...

VIM/VIDP-Process is widely used for melting high value charge materials, refining, alloying under vacuum or protective atmosphere and finally for casting under defined environmental conditions. The equipment is suitable and dedicated for manufacturing high end grades, especially used in the aerospace industry. Besides those well-defined and specified alloy manufacturing routes where the...

This study investigates the effect of Cu addition (0, 0.5, 1, and 2 wt.%) on the microstructure, mechanical properties, and heat treatment response of in-situ Al-15Mg₂Si-4.5Si composites. These composites are fabricated using gravity-assisted Low Superheat casting (LSC) technique and characterized by optical microscope, X-ray Diffraction (XRD), Scanning Electron Microscope (SEM), Electron...

White spot defects continue to present a serious risk for critical components in aerospace (and other) applications where material integrity is essential. Despite more than 50 years of investigation into white spots and related segregation defects in alloys such as Inconel 718, their precise origins and reliable prevention remain only partially understood. Even with advanced melting practices,...

A low cost adaption of bottom teeming of ingots, contact pouring, is found to raise the toughness of super duplex stainless steels by nearly an order of magnitude (ten times) by reducing the density of the damaging bifilm defect population. Simple additional features to divert the first damaged steel through the runner and away from the ingot, is predicted to further improve the ingot,...
