Monte Carlo (MC) simulations for recrystallization were performed using OIM (Orientation Image Microscopy) data sets to define the initial microstructures. Two types of OIM data sets were used as input to the simulations. One type was measured on a warm-rolled interstitial-free (IF) steel sheet. The results were strongly affected by the assumptions used to estimate the stored energy, which is t...

When lead-free solder alloys mix with lead-free component and board metallizations during reflow soldering, the solder interconnections become multicomponent alloy systems whose microstructures cannot be predicted on the basis of the SnPb metallurgy. To better understand the influences of these microstructures on the reliability of lead-free electronics assemblies, SnAgCu-bumped components were...

Recrystallization rate of ice crystals in 33% sucrose solutions, a model frozen dessert, was measured in the presence of antifreeze protein Type I (AFP type I) at -10°C, which is relevant to practical storage or distribution temperature of frozen dessert. The concentrations of AFP type I were set to 0.01, 0.1, and 1g/ml, respectively. Ice crystals during recrystallization process were observed...

The idea of control of mechanical properties in materials through designer processing techniques is promoted through this effort, in contrast to the standard control by alloying. Microstructure evolution through dynamic recrystallization is accurately modelled for the large thermo-mechanical deformation of hyperelastic thermoviscoplastic materials. An innovative solution strategy and a computat...

in the present work the recrystallization behavior of deep drawing grade al-killed low carbon steel sheets produced by mobarakeh steel plant (msp) has been studied. salt bath isothermal annealing has been applied to cold rolled samples and the resulted microstrucrures have been compared with the microstructure obtained from the box annealing process in msp. it is found that at 635 and 700ºc the...

The aim of the present review is to summarize recent achievements in development ultrafine-grained austenitic/ferritic stainless steels processed by large strain deformation. Various aspects microstructure evolution and its effect on properties are considered. paper starts from an overview various methods deformation that successfully used for producing metallic materials. Then, structural mech...

An Al-0.3%Cu alloy was deformed to high strains by cold rolling. The as-deformed samples were annealed at different temperatures until complete recrystallization. The cold rolling textures were determined by X-ray diffraction while the recrystallization textures and microstructures were characterized by electron backscatter diffraction. It was found that the rolling texture was characterized by...

The study reports that the combined use of in situ interlayer hot forging and post-deposition heat treatment (PDHT) could alter typical coarse oriented microstructure Ni-based superalloy 625 obtained by arc plasma directed energy deposition (DED) to a fine non-oriented condition. In synchrotron X-ray diffraction electron backscatter showed high-temperature (1100 °C/ 1 h) PDHT induced significan...

The dynamic and static softening behavior of R60702 commercial-purity Zr was studied through single-stage double-stage uniaxial hot deformation tests in the range 600oC–800 °C. microstructural evolution to compression loading for different conditions investigated using a combination optical microscopy electron back-scattering diffraction (EBSD). results show that fraction increases with an incr...

Plasma-facing components of future fusion reactors will have tungsten-based materials as armor. Annealed pure tungsten is brittle at room temperature restricting its use plasma-facing material, whereas plastically deformed behaves in general more ductile ambient temperatures. During operation material high temperatures, the deformation structure induced by plastic becomes unstable. Restoration ...
