EFFECT OF FINISH ROLLING TEMPERATURE ON MICROSTRUCTURE,TEXTURE AND PLANAR ANISOTROPY IN ALUMINUM ALLOY AA3004 SHEETS
AA3004 alloy is widely used in can making. The major concern in the production of canbodies is earing, which develop by high planar anisotropy of rolled sheet. Balance ofrecrystallisation and rolling textures together with a uniform and fine grain microstructure canminimize the earing. The effects of finish rolling temperature (FRT) on planar anisotropy,microstructure, texture development and m...
متن کاملHierarchical Fibers with a Negative Poisson’s Ratio for Tougher Composites
In this paper, a new kind of hierarchical tube with a negative Poisson's ratio (NPR) is proposed. The first level tube is constructed by rolling up an auxetic hexagonal honeycomb. Then, the second level tube is produced by substituting the arm of the auxetic sheet with the first level tube and rolling it up. The Nth ( ) level tube can be built recursively. Based on the Euler beam theory, the eq...
متن کاملAdvance In Micromechanics Analysis of Piezoelectric Composites
This paper presents an overview of micromechanics analysis of piezoelectric composites. Developments in micromechanics algorithms, finite element, and boundary element formulation for predicting effective material properties of piezoelectric composites are described. Finally, a brief summary of the approaches discussed is provided and future trends in this field are identified.
متن کاملExperimental and computational analysis of toughness anisotropy in an AA2139 Al-alloy for aerospace applications
Fracture toughness anisotropy of AA2139 (Al-Cu-Mg) in T351 and T8 conditions has been investigated via mechanical testing of smooth and notched specimens of different geometries, loaded in the rolling direction (L) or in the transverse direction (T). Fracture mechanisms were investigated via SEM and synchrotron radiation computed tomography (SRCT). Contributions to failure anisotropy are identi...
متن کاملReviewing the class of Al-rich Ti-Al alloys: modeling high temperature plastic anisotropy and asymmetry
In the last decades, the class of Ti-rich TiAl-based intermetallic materials has replaced many contemporary alloys till 900 °C. Due to higher oxidation resistance, 20% lower density and higher (about 150 °C more) operating temperature possibility of Al-rich TiAl alloys over Ti-rich side, phases from the Al-rich region of this alloy system are considered to be highly potential candidates for hig...
