Isothermal forging process can be use to produce complicated industrial parts from alloys with low formability like: aluminum and titanium alloys. In this method the problem of work-piece cooling during the forging is solved by using tools in the same temperature with billet therefore a less strain rate can be used in the process which results in a less flow stress. Decreasing of strain rate also causes a higher strain rate dependency which leads to a more formability. Isothermal forging can be used for a vast range of materials with high surface quality and accurate final dimensions. These advantages introduce this process as an attractive option to manufacture dental implants without machining. In this thesis the process of isothermal forging of an abutment implant is designed and a work-piece is produced. At first process simulation is performed to investigate process feasibility and calculate process parameters by Forg-3D software. Optimized speed of dies and initial billet dimensions are predicted by simulations. Required compressive force to forge the work-piece is also calculated and some methods are used to reduce this force. Then appropriate forming machine is chosen based on calculated force and ability of controlling temperature and forming speed. Then process dies are designed and manufactured. Appropriate lubricant and dies' material are chosen based on available documents. The work-piece is produced by calculated parameters and its properties like microstructure is investigated. Micro structural investigations show that the work-piece is forged in Alpha-Beta conditions therefore we can expect that the part has all of the Alpha-Beta forging advantages.
