Brief description of project :

I finished a project which Summary is as follow;

Nano- powders based Powder Metallurgy (PM) parts heavily used in the automotive industry, machinery industry, aerospace industry , machine manufacturing, iron and steel industry , dies and molds industry and the defense industry. High- frequency induction sintering method is a rapid prototyping method. If we applied load during sintering of powders, sintering temperature will be decreased. This rapid heating regime in nanostructured materials will to prevent grain growth. Densification will be faster and near to the theoretical density. Within the process, it is possible to gain over 97% of theoretical density by applying pressure. With this method, powders can be pressed and sintered to the desired shape close to the theoretical density. Non oxide ceramic and metal powders must be sintered under vacuum or protective gas due to the tendency for oxidation. Sintering is carried out under the melting temperature of powders representing the matrix composition. Conventional method, cause grain growth in nano sized particles. These phenomena results to decrease hardness and strength. With this work, sintering process will be completed in seconds by applying maximum 35 MPa pressure by the effect of high frequency induction. In this case sintered parts which are densier and having smaller grain sizes can be obtained. Oxidation of the graphite mold and graphane powders will be protected with a vacuum level up to 1X10-3 Torr by using sintering chamber during the experimental studies. As an energy source an induction generator which has 2.8 KW power capacity and 900 kHz high induction frequency will be used. Heating will be generated by magnetic flux spread from induction coil over graphite mold and powders. Under the melting temperature of the ceramic based powders will be sintered by induction at 5-35 MPa pressure under vacuum atmosphere in a minutes. Temperature of the graphite mold will be measured by infrared thermometer from the surface of the mold. This measurement will fix the induction frequency and power of the system. In spite of this measurement, speed of the controlled heating and fixed temperature will determine correctly. Project manager and researchers will be determining the configuration of the vacuum unit, pressing pressure, sintering durations and temperature. After the sintering operation of the ceramic compacts, density and hardness will measure and SEM, EDS, XRD and BET analyses will do. All mechanical properties and analysis will investigate for characterization and properties of the ceramics. With the results obtained for the production of ceramic compacts that provide the best properties will be optimized parameters. The scholarship students will perform high frequency induction sintering process in a vacuum. For characterization and determination of properties of the sintered compacts will done all necessary experimental tests, the effects of the production parameters will investigated for the compacts.

The aim of the project: It is planned to work on the induction sintering of new powders containing nano-graphene.
