Characterization and modeling of precipitation kinetics in an Al-Zn-Mg alloy

Abstract The precipitation kinetics in AA7108.70 Al-Zn -Mg alloy have been investigated by small angle X-ray scattering and transmission electron microscopy, and computer modeled by use of an internal state variable model concerning two regimes, (i) precipitation and growth and (ii) growth and coarsening. The modeling and experiments were done for isothermal heat treatment at 120, 140, 150, 160 and 170°C. These treatments were also compared with the industrial two step T6 treatment

“Girl Power, Selfies, and Sexiness”: An Investigation into the Neoliberal and Postfeminist Era of Influencer Marketing

In today’s social media-centered popular culture, fashion, and lifestyle influencers maintain rigid and sexist forms of femininity which are spread to a large consumer base through influencer marketing.
