The eddy current magnetic signature (EC-MS) method is a relatively new used to evaluate the residual stresses of ferromagnetic steels with higher sensitivity than other techniques. In this study, effects mechanical polishing and ferrite–pearlite structure on shape EC-MS signal were investigated in two experiments clarify effect compressive stress shape. first experiment, work-hardened layers sp...

Steel foam offers potential advantages over aluminum foams and other metallic foams. The inherent strength of steel combined with the reduced density of foam presents an attractive material with greater strength and modulus than light alloy foams, greatly reduced density relative to solid steel, and efficient energy absorption. However, thus far there have been few reports describing efforts to...

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 ...

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...
