Ultrasonic Monitoring of Recrystallization Textures in Aluminum
The present paper is an attempt to use ultrasonic velocity measurements to characterize the texture of an aluminum-magnesium alloy ( Al 5xxx ) and to compare the results with orientation imaging microscopy ( OIM ) results. The results are characterized in terms of three orientation distribution coefficients ( ODC's ), W400 , W420 , and W440 , each of which describes a particular forming anisotr...

متن کاملStrain rate dependence of yield stress and early Bauschinger effect in nanoscale aluminum films with different textures
Ultrafi ne grained (UFG) and nanocrystalline (NC) metals, unlike coarse-grained metals, often show inelastic strain recovery during unloading, which is referred to as early Bauschinger effect. Several experimental and simulation studies have focused on the microscopic origins of this unusual mechanical behavior. However, the strain rate dependence of early Bauschinger effect in UFG and NC metal...
متن کاملTextures in Dilaton Gravity
We examine the field equations of a self-gravitating texture in low-energy superstring gravity, allowing for an arbitrary coupling of the texture field to the dilaton. Both massive and massless dilatons are considered. For the massless dilaton, we find that non-singular spacetimes only exist for certain values of the coupling, dependent on the gravitational strength of the texture. For the mass...
