Texture Evolution in Low Carbon Steel Fabricated by Multi-directional Forging of the Martensite Starting Structuree
It has been clarified that deformation and annealing of martensite starting structure can produce ultrafine-grained structure in low carbon steel. This study aims to investigate the texture evolution and mechanical properties of samples with martensite structure deformed by two different forging processes. The martensitic steel samples were forged by plane strain compression and multi-directio...
متن کاملEstimation of Spray Lubrication and Die Temperature for Die Wear Life Prediction in Hot Forging
We have been developing a process design CAE system to predict die wear life in the process design stage for the hot forging of steel. Our goal is to reduce production costs by shortening the development period, while maximizing the life of the die. In our system, we use an expression that defines the relationship between die wear, die strength, and friction factors, such as die pressure, slidi...
متن کاملDecomposition of forging die for high speed machining
Today's forging die manufacturing process must be adapted to several evolutions in machining process generation: CAD/CAM models, CAM software solutions and High Speed Machining (HSM). In this context, the adequacy between die shape and HSM process is in the core of machining preparation and process planning approaches. This paper deals with an original approach of machining preparation integrat...
متن کاملOptimization of Flash, Billet Dimensions and Friction Factor in Closed Die Cold Forging Process
Three important parameters in designing a closed die for forging process are ratio of width to flash thickness, ratio of height to billet diameter and the friction factor. In this paper the influences of these parameters on the required force for the forging and percentage of die filling were investigated. It was found that by controlling the flash dimension, the material loss is reduced and t...
متن کاملEffect of Surface Morphologies on the Isothermal Oxidation Behavior of MCrAlY Coatings Fabricated by High-velocity Oxyfuel Processes
In this study, the effect of surface morphologies on the isothermal oxidation behavior of MCrAlY coatings fabricated by high-velocity oxyfuel (HVOF) processes was investigated. To do so, free standing coatings with as-sprayed and polished surfaces were isothermally oxidized at 1050°C. The thickness of the bond coat was approximately 380μm. The Ra of the as-sprayed and polished surfaces were 6.4...
