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—Powder metallurgy (P/M) is the only economic way to produce porous parts/products. P/M can produce near net shape parts hence reduces wastage of raw material and energy, avoids various machining operations. The most vital use of P/M is in production of metallic filters and self lubricating bush bearings and siding surfaces. The porosity of the part can be controlled by varying compacti...

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...

The background and necessity of application of numerical simulation method in research on friction materials of automotive brake are analysed. The numerical analysis methods of conversion of braking energy, distribution of friction heat, transfer of friction heat and thermal mechanical coupling, are discussed. The dynamic temperature field and thermal stress field of the same brake disc and two...

Mechanical alloying is a powder metallurgy processing technique involving cold welding, fracturing, and rewelding of powder particles in a high-energy ball mill. In this work, NiFe-TiC composite powders were prepared by mechanical alloying process using planetary high-energy ball mill. The effect of TiC addition by weight percent on the NiFe solid solution formation, grain size, lattice paramet...

Metallic materials having a porosity of 70% or more are generally referred as highly porous metals. In this study, pure nickel were produced by powder metallurgy route. the production process, potassium bromide was used both space-holder phase and an oxidation shield. method, firstly, powders mixed according to desired void ratio. The obtained nickel-potassium pressed in hydraulic press turned ...
