Evaluation of Shearing Time Sufficient for Effective Liquid Metal Processing

Melt shearing has been suggested to be an efficient means of structure refinement through oxide dispersion and fragmentation. One of the process parameters that needs to be optimized is the shearing time. In this paper, the effect of shearing time on alumina powder refinement was studied in a model system with water as a working fluid. The established time was taken as a first ...

Effects of H2 Atmospheres on Sintering of Low Alloy Steels Containing Oxygen-Sensitive Masteralloys

Processing of novel sintered steels with compositions including oxygen-sensitive elements requires deep understanding of the chemistry of sintering. The use of H2 atmospheres alleviates the oxygen transference from the base powder to the oxygen-sensitive particles. However, in H2, methane formation at 700–1200°C causes dramatic homogeneous decarburization of the part that affects ...

Effect of Pre-annealing on Sintering of Stainless Steel Fiber Felt

Stainless steel fiber felt is a class of unique porous metal materials. This study investigates the effect of pre-annealing on the sintering of stainless steel fiber felt through quantitative characterization of sintered joints based on synchrotron radiation experiments. The sintered joint size was found to follow a marked normal distribution in fiber felt samples sintered with and ...

Pilot Scale Production of Manganese Ferroalloys Using Heat-Treated Mn-Nodules

Pilot-scale experiments are one way to investigate the process patterns and the reaction mechanisms of processes and raw materials. To understand a process fully, both theoretical considerations as well as small-scale investigations are needed; nevertheless, the complex patterns of chemical reactions and physical phenomena can best be studied in pilot-scale investigations. After ...

Nanocomposite Cryogels Based on Poly (Vinyl Alcohol)/Unmodified Na+-Montmorillonite Suitable for Wound Dressing Application: Optimizing Nanoclay Content

A new type of nanocomposite cryogels containing polyvinyl alcohol and 0–10% of hydrophilic natural Na-montmorillonite (Na+-MMT), free from any modification, were prepared with a freeze–thaw process. The effects of nanoclay content and the sonication process on the morphology and thermomechanical properties, equilibrium water content (EWC), and the water vapor transmission rate ...

Innovative Concept for the Recovery of Silver and Indium by a Combined Treatment of Jarosite and Electric Arc Furnace Dust

Industrial wastes such as slags, dust, or precipitation residues contain significant amounts of valuable metals like zinc, lead, and copper as well as precious metals like silver and indium. Nevertheless, a lot of these waste materials are not recycled, and therefore, many valuable metals end up being sent to landfills. Because of harmful components in the waste, it is often ...
