Al-x wt.% Fe bulk alloys were fabricated from a powder mixture of pure Al and x wt.% of Fe, where x = 2 wt.%, 5 wt.% and 10 wt.%. Initially, as-mixed mixtures were processed using a mechanical-alloying (MA) technique in an attritor for 4 h. The milling was performed in an argon atmosphere at room temperature followed by the sintering of the milled powders in a high-frequency induction furnace Corrosion Resistance and Passivation Behavior of B passivation behavior of S31254. The addition of boron in this metal has not yet been studied in terms of passivation and corrosion resistance. Boron atoms segregate around the grain boundaries and result in a lowering of the grain boundary energy and inhibition

Most of the work on SPD, till date, has utilized very low strain-rates (~0.1/s to 10/s), except for few recent works wherein strain-rates of the order of 10 3 were utilized [10-12] and resulted in

Grain size versus microstructural stability in the high

Jan 05, 2017 · 1. Introduction. Mechanical properties of metallic materials are highly sensitive to the grain size. At room temperature, according to the Hall-Petch relationship, a reduction in the grain size causes and increase of the yield strength , .At high temperatures, fine grain sizes are required to obtain a good superplastic response at high strain rates and relatively low temperatures .

Impact of thermomechanical texture on the superelastic

Specifically, in severely worked NiTi, bands of [100] grains occur whose orientation deviates markedly from the surrounding matrix; these bands have an unusually large impact on the initiation and the propagation of martensite, and hence on the mechanical response. Influence of Homogenization on Microstructural Response The evolution of the microstructures and properties of large direct chill (DC)-cast Al-Cu-Mn alloy ingots during homogenization was investigated. The results revealed that the Al-Cu-Mn alloy ingots had severe microsegregation and the main secondary phase was Al2Cu, with minimal Al7Cu2Fe phase. Numerous primary eutectic phases existed in the grain boundary and the main elements were segregated

Long-term effects of contralesional rTMS in severe stroke

Neurophysiological response to stimulation was assessed through cortical excitability evaluations. The relationship between functional and neurophysiological response to rTMS and microstructural integrity of transcallosal motor fibers were searched using diffusion Mechanical properties and energy absorption Mar 01, 1997 · A typical compressive response of a high density elastomeric foam, shown in Fig 1, generally contains three regions of interest:(I) a linear-elastic region, governed by strut bending; (II) a relatively flat, or slowly increasing stress-strain response, accompanied by strut buckling and the localized collapse of pores; and (III) an

      The distinct material responses to load-unload cycles in the two PTB models matches the differing microstructural changes in collagen and elastic fibers in these two models of preterm birth. Improved understanding of the impact of microstructural changes to mechanical performance of the cervix will provide insights to aid in the development of Assessment of microstructural and electrochemical behavior Nov 05, 2017 · Assessment of microstructural and electrochemical behavior of severely deformed pure copper through equal channel angular pressing.
