The Young's modulus and the internal friction of amorphous Fe 90 Zr 10 alloy were measured near the Curie temperature using the vibrating reed technique.The modulus shows softening around T c ≈ 227K and the internal friction undergoes drastic increase at T c . It is found that both the Young's modulus and the reciprocal of internal friction are inversely proportional to the magnetic susceptibility in the paramagnetic phase.
The influence of initial texture on the formation of primary twin system of AZ31
Magnesium rolled plate was investigated in this work. Uniaxial compression tests were carried out
on samples cut along the rolling direction (RD) and normal direction (ND) of rolled AZ31 Mg plate
at various temperatures (RT, 150, 200, 250, 300, 350, 400, 450°C) with the fixed strain rate
(0.01s-1). The results showed that the primary twinning system of AZ31 Mg alloy (c-axis extension
twin) occurred actively in the RD compression specimens, which promoted homogeneous
deformation as compared to the ND compression specimens. The effect of temperature on the
formation of deformation twins was also investigated, and slip/twin transition temperature was
found to be 250°C.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
