Abstract: In this study, an evaluation quantitative approach is introduced not only to depict the plain individual effect of the influence of compact height to diameter ratio, compacting pressure, and alumina (Al2O3) content on the relative density, Vickers hardness values, and compression properties of the sintered Al-4Cu-xAl2O3 composites is obtained through Design Expert 11.

Abstract: Slag vortexing, Reoxidation of the liquid steel from tundish open eye with high superheat casting are main causes behind many customer complains as well as high rejection of metal in integrated steel plants. In present investigation a novel stopper rod with refractory water cooled sub-chamber has been proposed. This is capable to reduce 60% skull generation and will help to reduce supeheat of liquid steel within the tundish nearly 50%.
Abstract: In the present study a finite element model of the FSW process is built and a FSW but weld of two aluminium alloy 2024-T3 plates is simulated using a fully coupled thermo-mechanical analysis. Besides the welded panels, the model includes the backing plate and the welding tool as physical bodies, which makes the simulations more realistic. The model also includes conductive heat transfer between the contact surfaces of the FSW tool, the aluminium plates and the backing plates, heat generation due to friction between the tool and the welded plates and heat loss to the ambient air due to convection.

Abstract: Ferrous powder metallurgy (P/M) has advanced significantly over the past thirty years as a cost effective and efficient processing technique to make intricate near net shape parts. Parts made by P/M compete favourably, in terms of cost, recycling environment and properties, with conventional processing techniques such as stamping, casting and forging.

Abstract: A model is proposed to simulate the operation of a dry rotary drum magnetic separator. The model uses a probability distribution of the trajectories followed by the particles ejected from the rotating drum of the magnetic separator. Empirical relationships are used to relate the particle trajectories following their ejection to the drum rotation speed and magnetic field. The model is calibrated using the test results from a pilot scale magnetic separator and validated using data collected from an industrial dry magnetic concentration plant. The application of the model as implemented into a simulator is illustrated with control and optimization examples for a dry magnetic separation plant.

Abstract: AA6061 alloys with different content of erbium were prepared by ingot-metallurgy method. The influences of erbium (Er) on the microstructure and mechanical properties of AA6061 alloy were investigated by optical microscopy (OM), scanning electron microscopy (SEM) with energy dispersive spectrometer (EDS, transmission electron microscopy (TEM) and X-ray diffraction (XRD) analysis.
Abstract: Heat treatment is a practical approach that has been thoroughly studied to strengthen Mg alloys for different applications. The aim of this work is to study the effect of the addition of Mn and a heat treatment process on the mechanical and in vitro corrosion properties of a Mg-Zn-Ca-based alloy.
