Three Dimensional Optical Microstructure Analysis of Ferrite and Pearlite Phases in a Medium Carbon Steel
This work presents a three dimensional microstructural analysis of medium carbon steels, based on serial sectioning using optical microscopy. The microstructural phases considered here are ferrite and pearlite. Typically conventional 2D microscopy is used to analyze these phases, with eddy current or ultrasonic methods as alternatives. Medium carbon steel samples were heat treated in a furnace ...
متن کاملWork-Hardening and Deformation Mechanism of Cold Rolled Low Carbon Steel
The study reports the mechanical property and microstructure of cold rolled low carbon steel and its work-hardening behavior in the deformation process. The tensile test in room temperature of low carbon steel was implemented for the different cold rolling deformation, the stress-strain curve was draught according to the relationship between strength and deformation and fitted for the polynomia...
متن کاملEnhancement of mechanical properties of low carbon steel based on heat treatment and thermo-mechanical processing routes
Thermal treatments and thermo-mechanical processing routes were applied on a conventional structural steel (st37 steel: 0.12C-1.11Mn-0.16Si) for improvement of tensile properties and enhancement of work-hardening behavior. Full annealing resulted in a sheet with coarse ferrite grains and pearlite colonies arranged alternatively in distinct bands, which showed high ductility, low strength, and t...
متن کاملPrediction of Bainite Intervention in Ferrite-Pearlite Forging Steel I. Modeling
The successive ferrite (α) + pearlite (P) transformations from austenite (γ) have been modeled to predict the intervention of bainite in as-forged medium-carbon manganese steels. The kinetics of the diffusional transformations were calculated based on the classical nucleation-growth theory coupled with the CALPHAD multi-component thermodynamics. The description of growth rate of proeutectoid-α ...
متن کاملFrictional Strain Hardening-softening in Experimental and Numerical Investigation of Arching Effect
In the current paper the results of a numerical simulation that were verified by a well instrumented experimental procedure for studying the arching effect over a trapdoor in sand is presented. To simulate this phenomenon with continuum mechanics, the experimental procedure is modeled in ABAQUS code using stress dependent hardening in elastic state and plastic strain dependent frictional harden...
