In the present study, statistical analysis for previously reported cut edge fatigue test results is performed. Experimental tests are conducted machined, plasma, and fiber laser-cut S960 edges to verify effect of yield strength quality, study cutting method on performance. were complemented with hardness residual stress measurements metallurgical analyses electron backscatter diffraction (EBSD)...

In the present work, nano/ultrafine structured Al/Brass composite was produced by accumulative roll bonding (ARB) up to eight cycles. The evolution of grain refinement and deformation texture and their effect on the mechanical properties were investigated. It was observed that by increasing the ARB cycles, due to the difference in flow properties of the metal constituents, brass layers necked, ...

• The lamellar component of the alloy was spheroidized after ECAP deformation. by boundary-splitting mechanism. evolution primary alpha phase is controlled continuous recrystallization. Burgers orientation relationship between α and β phases found. In this work, electron backscatter diffraction (EBSD) applied for microstructural characterization advanced Ti-5.7Al-3.8Mo-1.2Zr-1.3Sn subjected to ...

Electron backscatter diffraction (EBSD) was used to determine the orientation of mechanically twinned grains in Carrara marble experimentally deformed a small strain (?4%) at room temperature and moderate confining pressure (225 MPa). The thicknesses deformation twins were mostly too permit determination their by EBSD but it proved possible measure orientations calculating twin from host grain ...

High-purity titanium has been subjected to dynamic compression with a strain rate of 103 s−1 activate {112-2} and {112-4} contraction twins. Electron backscatter diffraction (EBSD), transmission electron microscopy (TEM), high-resolution TEM (HRTEM) were performed observe the morphologies twin boundaries The results show that twins are predominant twinning mode, as well formation due change in ...

A systematic study of crack tip interaction with grain boundaries is critical for improvement of multiscale modeling of microstructurally-sensitive fatigue crack propagation and for the computationally-assisted design of more durable materials. In this study, single, biand large-grain multi-crystal specimens of an aluminum-copper alloy are fabricated, characterized using electron backscattered ...

Q&P1180 is a typical third generation of advanced high strength steel. In this paper, the microstructure evolution steel during uniaxial tension investigated comprehensively by using in situ neutron diffraction technique, electron backscatter (EBSD), scanning microscope (SEM) and elastic-visco-plastic self-consistent with phase transformation (EVPSC-PT) model. Tempered martensite (TM) determine...

Morphologies of retained γ grains in TRIP steels are a very important factor for understanding the relationship between microstructure and mechanical properties steels. We have investigated serial sectioning technique using scanning electron microscope (SEM) equipped with an backscatter diffraction (EBSD) focused ion beam (FIB) to reconstruct 3D In this paper, FIB fabrication condition dependen...

The plastic deformation modes of commercially pure titanium (CP-Ti) were studied using an in situ tensile test monitored by electron-backscatter-diffraction (EBSD) assisted slip trace analysis. strain was primarily accommodated prismatic slip, followed twins and pyramidal slip. transmission between two adjacent grains predicted the geometric compatibility factor m?, which influenced not only de...
