Investigation of microstructure and mechanical properties of low carbon steel sheets after severe plastic deformation in corrugation dies
Recently, bulk nano-structured materials produced by severe plastic deformation (SPD) have attracted scientists attention. Materials produced by SPD are of great importance because of (1) non-porous structure, (2) great mechanical properties such as high strength and toughness and (3) proper dimension for mechanical and physical testing. Several methods have been introduced for imposing the s...
متن کاملThermomechanical Damage Modeling of F114 Carbon Steel
Abstract—The numerical simulation based on the Finite Element Method (FEM) is widely used in academic institutes and in the industry. It is a useful tool to predict many phenomena present in the classical manufacturing forming processes such as fracture. But, the results of such numerical model depend strongly on the parameters of the constitutive behavior model. The influences of thermal and m...
متن کاملPlastic Flow and Grain Refinement Under Simple Shear-Based Severe Plastic Deformation Processing
In the present work, effects of loading scheme and strain reversal on structure evolution are studied by using high pressure torsion (HPT) and twist extrusion (TE) techniques. High purity aluminum (99.99%) was processed at room temperature up to a total average equivalent strain of ~4.8 by TE and HPT with two deformation modes: monotonic and reversal deformation with a step of 12 ̊ rotation. It ...

متن کاملAN INVESTIGATION TO BAINITE FORMATION MORPHOLOGIES IN NI-CR BEARING LOW CARBON STEELS THROUGH THERMOMECHANICAL PROCESSING
The presence of bainite in the microstructure of steels to obtain a proper combination of strength and toughness has always been desired. The previous works however have shown that the presence of preferred bainite morphologies in the microstructure of any steel would not be readily accessible. In addition, the appearance of different bainite morphologies in the microstructure of any steel is d...
