A study of mechanical isotropy of continuous cast and direct chill cast AA5182 Al alloys

Field Emission Gun Scanning Electron Microscopy with Electron Back Scatter Diffraction for Texture, Formability and Fatigue Studies of Advanced Materials

“…However, the alloys produced by the continuous cast technology often show an inferior formability, compared to the alloys produced by conventional direct chill casting (DC). A strong P texture component {011}〈566〉 is often formed in recrystallized CC Al alloys, especially in 3000 series Al alloys [1][2][3]. It has been recognized that, in a DC Al-Mn alloy, the P component is formed due to the concurrent precipitation effect, i.e., precipitation of Al 6 Mn upon heating of the deformed and supersaturated alloy [4,5].…”

The corrosion of AA2037 aluminum alloy in alkaline aqueous solution studied using slow positron beam spectroscopy

“…Aluminum alloy plates produced by this method present cost-savings of about 25 % over the conventional direct chill cast method [22]. Vacancy-solute interaction and precipitates of hot bands of continuous-cast AA2037 aluminum alloy after high-temperature annealing and/or artificial aging were studied by PAS [23,24].…”

Texture evolution in AA5754 alloys deformed in tension

“…Compared to SC alloys, the DC materials contain more uniform microstructure with larger particles [2,3]. The differences in the microstructure and texture of DC and SC alloys affect their mechanical behaviour during subsequent thermomechanical processing.…”

“…During fast solidification SC alloys inherit heterogeneous spatial distribution of fine intermetalic particles, leading to a reduced tensile elongation and bendability. As a result, SC products exhibit an inferior formability and a larger mechanical anisotropy than DC materials [3][4][5]. * Corresponding author.…”
