Study of the Industrial Precision Manufacturing and Metallic Alloys with Respect to Economic Considerations

In this report according to the research results and approaches that used, it is utilized and illustrated why these papers are suitable for this research. The best position for explaining topic is here, because for understanding better the concept and the area of research, it is necessary to write briefly at the beginning of the article about topic. It is attempted to design new piston (porous piston) not only to have a good resistance in mechanical properties but also provide lower weight comparing to the previous ones. The most important thing in this work is to be aware of the effect of vibration, vacuum and over pressure during investment casting which by this way we can produce porous structure. By using the existing results of several papers, we will attempt to cast porous piston and optimize it to have the best mechanical properties. As we know engine pistons are one of the most complex components among all automotive or other industry field components. The engine can be called the heart of the car and piston maybe considered the most important part of an engine.
