Abstract:

In centrifugal casting, molten metal is introduced into a mould which is rotated at high speed. The centrifugal force helps to fill thin sections but this benefit may be offset by the effect of the turbulent flow on the casting quality. In this research, the effect of direct and indirect gated mould designs on the quality and reliability of aluminium alloy investment castings made by centrifugal casting was investigated. The scatter in the ultimate bend strength and the modulus of elasticity was analyzed using the Weibull statistical technique, which showed that the Weibull modulus of both pro

Abstract:

The centrifugal casting process is a common method for manufacturing the tubes, etc. Due to its high temperature and invisible mold, it is really difficult to know the mechanism of molten steel inside the mold. It is important to know the mechanism of the molten steel inside mold, since it will help the manufacturer to know more accuracy of the flow of the molten steel so that it can work for improving the productivity and quality of the products. Casting funnel design is the designed by Åkers for their funnel which will result in different flow behavior. In thesis work, casting funnel design

Abstract:

Les alliages TiAl sont un groupe de matériaux important pour les industries automobile et aérospatiale, de par leur faible densité et bonne tenue mécanique à haute température. Cependant, à cause de leur forte réactivité à l’état liquide, au moment de couler ces alliages, il faut utiliser une faible surchauffe pour limiter la contamination. La coulée centrifuge est une option pour améliorer le remplissage du moule à faible surchauffe. En coulée centrifuge, l’effet de la poussée d’Archimède sur le mouvement du liquide est renforcé, ce qui modifie l’écoulement par l’effet combiné de la force cen

A simplified 2 X 2 feedback linear dynamical model is developed based on first principles and engineering intuition due to the lack of experimental data from the TRC machine.

Significant research has been undertaken into the use of intermetallic gamma titanium aluminide alloys (γ- TiAl). The first-rate high temperature properties of the alloys, coupled with an inherent low density, make them an attractive prospect for the aerospace and automotive industries. In this work, the utilisation of γ-TiAl as a structural material, specifically as low pressure (LP) turbine blades for aerospace engines, was considered as a replacement for conventional nickel-based superalloys. These alloys however are difficult to work with, being highly reactive in a molten state, dictating

Abstract:

Thermoplastic injection technology is widely used in all sectors of consumer electronics and automotive industry. The biggest advantage of this manufacturing technology is a high degree of automatization and good reproducibility of the manufacturing process. Another advantage is the possibility of recycling of the gating scrap and defective products. The main task of this work is to calculate the necessary parameters for the injection process, which takes place at the designed injection form. Next part is technical design which includes choice of standard parts of injection mold and idividual

The theoretical model comprises two groups of steady conservation equations of mass and momentum and the governing equations are solved numerically with k-ε turbulence model and iterative SIMPLE(Semi-Implicit for Pressure-Linked Equations) algorithm to determine the flow property. The numerical results indicate that the melt liquids of titanium compound metal flow near the walls in the high rotation rate. With the high rotation rate, the

The main reason is that the physical property would be different when the normal alloy material is mill grinded into Nano-scale powder which is useful for current science. The most important skill is that how to grind the general alloy material into Nano-scale. For the current normal physical grinder the main problem is that grinding generates heat which has negative effect for grinder and powders. Additional methodology and cost are required to reduc
