The continuous development of technology in automotive manufacturing process demands new solutions which is largely de-pendent on the development of lightweight, nonpollution for the environment materials of improved mechanical properties and also with a low cost production. According with these required characteristics of materials, the aims of this paper were to manufacturing Al-SiCp composit...

In this study carburizing and boronizing processes were applied to powder metallurgy steel specimens and the mechanical and tribological properties of the substrate and coatings were evaluated under various process conditions.&#10The specimens, made from industrial test pieces, were carburized in a powder pack for a duration of 2-5 hrs at 850-950 ˚C. Similar specimens were pack boronized for 4 ...

Beta-titanium alloys containing only fully biocompatible elements are very perspective materials for production of bioimplants. They have good properties for use as biomaterials, including above mentioned biochemical compatibility, low elastic modulus (important for biomechanical compatibility), in comparisson with previously used alloys. Moreover they are suitable for forging. Perspective meth...

Abstract In order to reduce defects such as pores, gold phases and cracks in powder metallurgy, scholars have studied the densification process of metallurgy. Based on study metallurgy deformation mechanism, this paper classifies summarizes numerical simulation theory methods. At present, is carried out mainly macroscopic, mesoscopic microscopic directions. Macro scale an application finite ele...
