Seeking high-performance computing methods to solve the problem of a large amount calculation, low calculation efficiency, and small simulation scale on traditional single central processing unit (CPU) platform is great value study micro-structure. In this study, based three-dimensional multi-phase-field model KKSO coupling phase-field solute field, open language (OpenCL) + graphics (GPU) heter...

 One of the surface defects that arise in sheet metal working is when the part removes from the die. Since there are no external forces to make this defect, the origin of such fail is known as residual stress. Residual stress can develop in sheet metal forming due to non uniform deformation. In this paper, the workpiece is carbon steel with different volume fractions and arrangement of ferrite ...

Purpose. Investigation of the supercooled austenite decay kinetics during continuous cooling steel with 0.84 % C, 0.44 Si, 0.95 Mn, 0.01 B, 0.0006 Ca for railway rails a new generation increased operational properties to develop parameters differential cooling. Method. The investigation was carried out using thermal analysis. Samples were cooled at different rates, temperature control performed...

Abstract: A well-known challenge is to predict the transformations occurring during metal alloys welding aiming control weldment properties. Thus, this study presents a Thermo-Mechanical-Metallurgical model numerically thermal history, solid-state phase transformations, solidification microstructure and hardness distribution after of high strength low-alloy steels. The was implemented in an in-...

The cylinder liner is one of the important parts a diesel engine. Gray cast iron main material for manufacturing liners due to its good casting performance, convenient processing wear resistance and low cost. In present work, effects vanadium (V) tin (Sn) on microstructure properties gray were studied. Results show that increasing contents V Sn can not only refine graphite, but also reduce pear...

Abstract This work presents a multi-scale modelling framework for thermo-mechanical behaviour of Compacted Graphite Iron cast iron. A general thermo-elasto-visco-plastic model is developed to describe the matrix (pearlite) behavior under cyclic loading, which parameters are identified from tests on pearlitic steel. The pearlite takes into account temperature dependent rate-dependency and kinema...
