Flow stress of aluminum
WebSep 22, 2024 · The flow stress anisotropy of aluminum foil is affected by the texture components. Schmid factor analysis indicates that when tensile testing at 0° to the rolling direction, only cube texture shows a high Schmid factor. Both cube texture and Cu texture have high Schmid factors when tensile testing at 90° to the rolling direction. WebDec 31, 2013 · The relationship between the temperature, the strain rate, and the flow stress were discussed. A constitutive model based on the updated Fields-Backofen equation was established to describe the flow behavior of 6111-T4 aluminum alloy during the warm tensile tests.
