In the conducted investigations, aluminium dross, i.e. solid waste formed in the production and recycling of aluminium, was used as one of the basic raw materials to obtain a material characterised by insulating and exothermic properties, applied to heat riser heads in the process of iron or steel casting. The product was obtained by filtrating the slurry. In the raw mix, aluminium dross played...

This study deals with the experimental measurements and numerical predictions of alloy shrinkage factors (SFs) related to the investment casting process. The dimensions of the A356 aluminum alloy casting were determined from the numerical simulation results of solidification, heat transfer, fluid dynamics, and deformation phenomena. The investment casting process was carried out using wax patte...

Al-7Si-0.5Mg aluminum alloy semi-solid slurry with good spherical grains was prepared by gas induced process (GISS) and the effects of both holding time medium addition on microstructure were investigated. These two parameters have a great influence solid fraction, size sphericity grains. With increased from 85 s to 270 s, phase fraction decreased ~0.77 ~0.67, average grain ~95 μm ~225 shape fa...

The bioadhesive buccal film drug delivery technology that increases the safety, effectiveness, and stability of active pharmaceutical ingredients is main focus current article. cutting-edge since it offers a better way to maximise treatment effectiveness. medications are used increase bioavailability have high first-pass metabolism ideal for this strategy. Rolling, hot-melt extrusion, solid dis...

During the solidification, and then cooling, generally a shrinkage gap or mechanical interaction (grip or slip) can occur between the casting and the mold. The character of interaction is decided by the shape of casting. Both these phenomena occur in most real castings. Shrinkage gap, and specifically its width, determines the heat flow between cast and mold, while the mechanical interactions l...

We consider the problem of dynamic coupling between the rapid thermal solidification and mechanical compression of steel in twin-roll steel strip casting. In traditional steel casting, molten steel is first solidified into thick slabs and then compressed via a series of rollers to create thin sheets of steel. In twin-roll casting, these two processes are combined, thereby making control of the ...

The use of aluminum alloys in various industries, especially the automotive industries, to have less structural weight, is on the rise. The use of semi-solid forming process in addition to changes in the microstructure which improves the mechanical properties can reduce the volume of production and ultimately lead to the improvement of the structural weight. In this paper, optimization of the g...
