Multiple Solutions: A Key to Strengthening the Generalization Skill in Mathematic-Like Thinking   Z. Rahimi* E. Talaa'ee, Ph.D.** E. Reyhaani, Ph.D.*** H. Fardaanesh, Ph.D.****   Emphasizing multiple solutions can help with the strengthening of the generalization skill. To test this hypothesis, a group of high school students in math and experimental sciences was selected in or...

A high-throughput methodology is proposed, based on the combination of diffusion couples and advanced nanomechanical testing methods, to directly measure alloying effects critical resolved shear stress (CRSS) individual deformation modes in Mg alloys. The tested Mg-Zn alloys by assessing effects, up Zn contents 2 at.%, basal slip, extension twining pyramidal slip two metallurgical conditions: a...

An innovative fatigue strengthening solution for metallic structures that takes advantage of the shape memory effect an iron-based alloy (Fe-SMA) and bridging mechanism offered by bonding technique has been proposed examined. Fatigue tests on cracked steel plates with bonded carbon fiber-reinforced polymer (CFRP) nonprestressed prestressed Fe-SMA strips were conducted. The experimental results ...

Tailoring the partitioning behavior of solid solution strengtheners is a crucial design strategy for advanced Ni-based superalloys. The goal this study was to maximize enrichment Mo, Re, Ru and W in γ-matrix phase. To determine composition dependency behavior, set polycrystalline superalloys with varying contents these solution-strengthening elements W-containing single-crystalline alloy series...

Single β phase titanium alloys are used for fabricating biomedical devices, and it is desirable to improve the strength of these alloys. In this study, tensile Ti-35 at.% Ta with a single was improved using oxygen solid solution strengthening mechanism also investigated. The lattice constants calculated from X-ray diffraction data increased an increase in content. This result suggests that atom...
