The Review Study of Forging and Effects on the Produced Part

There are several method for forming bulk material, such as forging, rolling and extrusion. Every of these methods have advantages and dis-advantages of their selves. Forging process is one of the most common of them that include a die, press and in some case heater with controlling system, and has a special place in automotive, military and aerospace industries due uniformity of the final product, speed of process, repeat-ability and low final cost. Forging die has an upper and lower part. There are numerous studies about simulation, die design, load estimation, understanding and optimizing this process. In this article, forging is dis-cussed briefly. This study is conducted in the field of process tools, analytical methods, simulation and result comparison of analytic, analysis and excremental conditions and also the effect of the forging in micro-structure and mechanical properties(such as tensile and hardness) in some cases studied briefly as a review of other researches.
