The effect of room temperature pre-ageing on tensile and electrical properties of thermomechanically treated Al-Mg-Si alloy [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy, 2002
A commercial Al - 0.62%Mg - 0.57%Si was thermomechanically treated (TMT). The TMT process included solution treatment, room temperature preageing, drawing (e=95%) and final ageing.

Mass radius relation of compact stars in the braneworld

open access: yes, 2014
The braneworld scenario, based on the fact that the four dimension space-time is a hyper-surface of a five dimensional manifold, was shown to deal in a satisfactory way with the hierarchy problem.

The mechanical behaviour of an ultrafine grained Ti-47Al-2Cr (at%) alloy in tension and compression and at different temperatures [PDF]

open access: yes, 2011
A bulk ultrafine grained (UFG) Ti-47Al-2Cr (at%) alloy has been produced using a powder metallurgy process that combines high energy mechanical milling (HEMM) of a mixture of Ti, Al and Cr powders to produce a Ti/Al/Cr composite powder and hot isostatic ...
