In the field of casting aluminum alloys, integrated computational materials engineering (ICME) is a relatively emerging trend. Through mathematical modeling, new alloys that meet the requirements of the industry can be generated. However, the development of a new alloy with particular attributes is still an enormous challenge; testing the individual possible combinations is numerous. There are several dozen different metals, and even if the alloys are binary, there are many alternatives. This makes ICME a suitable and practical tool to predict the behavior of new alloys. In this paper, the presented model when used to characterize the behavior of alloys shows a reliability level superior to 90%. The mathematical description of the model is also presented. It can be used as a reliable tool for the selection of the desired elements in its composition letting the selection of the most important properties according to the industrial needs and standards.

The desired technology for manufacturing light-weight components from metal alloys mostly aluminum and magnesium alloy is Die casting. High pressure die casting requires the liquid metal to be forced at high speed and pressure through a metal pipe. In our study, we seek to study Aluminum filling under high pressure in two different pipes, cylindrical and conical pipes. Two cases are considered for the cylindrical pipe, when the pipe vertical and when the pipe in inclined at an angle of 450 with the horizontal. The governing equations are obtained and the results are compared. The governing equations are obtained and modeling is done using ANSYS FLUENT. The results show that inclining the cylindrical pipe causes a shift in the oscillations and the inclined pipe has slightly lower amplitude of oscillation implying a greater loss of energy due to the inclination. The inclined cylindrical pipe has higher damping compared to the vertical cylindrical pipe. It is also evident that the conical pipe has higher oscillations than the cylindrical pipe implying a greater loss of energy for the conical cylindrical.

Abstract. Inappropriate air vent design always induced porosities in thin and complex shape of high pressure diecasting (HPDC) products. Chill block installation was preferred to improve permanent molds for reducing porosities. There were not regular to obtain an appropriated chill vent from this method unless an experience of mold makers. This research was performed to investigate and evaluate the chill block performance in the HPDC mold of motorcycle fuel caps. The HPDC mold of the thin and complex shape product without chill vents was improved by inserting of chill blocks. The motorcycle fuel caps of molds with and without chill vents were compared to verify size and position of porosity defects. Furthermore the HPDC simulation using the finite element analysis (FEA) had been performed according to the physical experiment. The FEA results were compared and in agreement with the experimental data. Therefore an improvement of the HPDC mold should be used FEA to obtain the best way of the air vent design.
