Plastically deformed low-carbon steel has been analyzed by nondestructive three-dimensional orientation and strain mapping using scanning X-ray diffraction microscopy (S3DXRD). However, the application of S3DXRD is limited to single-phase alloys. In this study, we propose a modified analysis for dual-phase alloys, such as ferrite–pearlite carbon steel, which composed grains detectable spots pha...

This study investigated the true stress (σ)–true strain (ε) relationship up to plastic deformation limit in ferrite–pearlite (FP) steel at various temperatures. We found that a decrease temperature resulted an increase lower yield strength (LYS) and tensile (TS), both uniform total elongations. When was increased from 673 773 K, TS elongations decreased due blue brittleness. In σ–ε of FP temper...

We study the statistics of level spacing of geometric resonances in the disordered binary networks. For a definite concentration p within the interval [0.2,0.7], numerical calculations indicate that the unfolded level spacing distribution P(t) and level number variance Sigma(2)(L) have general features. It is also shown that the short-range fluctuation P(t) and long-range spectral correlation S...

Two experiments used procedures similar to those used by R. L. Greene (1989) to test the 2-process theory of the spacing effect and, in particular, the contextual-variability subtheory that applies to free-recall performance. Experiment 1 obtained a spacing effect in free recall following intentional learning but not following incidental learning, contrary to a previous result supporting the 2-...

Microstructural banding is defined as alternating layers of two different microstructures in steel, often ferrite and pearlite. It is caused by fluctuations in the concentration of alloying elements, primarily manganese, due to microsegregation introduced during solidification. In this thesis, a model is presented to simulate banding using phase transformation kinetics theory. An existing progr...
