We report a computational 'alloy by design' approach which can significantly accelerate the design process and substantially reduce the development costs. This approach allows simultaneously optimization of alloy composition and heat treatment parameters based on the integration of thermodynamic, thermo-kinetics and a genetic algorithm optimization route. Novel steel compositions and associated...

Oxide dispersion strengthened (ODS) steels with different contents of zirconium (denoted as 16Cr ODS, 16Cr-0.3Zr ODS and 16Cr-0.6Zr ODS) were fabricated to investigate the effects of Zr on strengthening mechanism of Al-alloyed 16Cr ODS steel. Electron backscatter diffraction (EBSD) results show that the mean grain size of ODS steels could be decreased by Zr addition. Transmission electron micro...

Near-surface mounted (NSM) fiber-reinforced polymer (FRP) reinforcement has been found to perform efficiently as a flexural/shear strengthening technology for reinforced concrete (RC) members, while offering some additional practical advantages with respect to the most widespread technique of externally bonded laminates. This paper presents a design procedure for flexural and shear strengthenin...

ACT la a computer simulation program that uses a propositional network to represent knowledge of facts and a set of productions (conditionact ion rules) to represent knowledge of procedures. There are currently four different mechanisms by which ACT can make additions andmodifications to its set of productions: designation, strengthening, generalization, and discrimination. Designation ...

Sleep is thought to consolidate changes in synaptic strength, but the underlying mechanisms are unknown. We investigated the cellular events involved in this process during ocular dominance plasticity (ODP)-a canonical form of in vivo cortical plasticity triggered by monocular deprivation (MD) and consolidated by sleep via undetermined, activity-dependent mechanisms. We find that sleep consolid...

A new generation of alloys, which rely on a combination of various strengthening mechanisms, has been developed for application in molten salt nuclear reactors. In the current study, a battery of dispersion and precipitation-strengthened (DPS) NiMo-based alloys containing varying amounts of SiC (0.5-2.5 wt %) were prepared from Ni-Mo-SiC powder mixture via a mechanical alloying (MA) route follo...

Institutionalization of Water Users’ Cooperatives (WUAS) is one of the strategies for cooperative irrigation management, which lays the foundation for the participation of farmers in tackling water shortage challenge to reach the objectives of sustainable management of agricultural water in an efficient manner. The main purpose of the present study was to identify the grounds for improving WUAs...
