of the refined and dispersed α+β phase on the basis of high dislocation density by pre-deformation below recrystallization temperature. The tensile strength decreases with the increase of pre-deformation reduction. The optimal processing parameters of LTTMT for TC4 alloy are as follows: solution treatment at 900 ℃ for 15 min, pre-deformation in the range of 600-700 ℃ with a reduction of 35......
Trans. Nonferrous Met. Soc. China 25(2015) 1383-1390 Effect of pre-deformation on aging creep of Al-Li-S4 alloy and its constitutive modeling Meng WANG1,2, Li-hua ZHAN1,2, You-liang YANG1,2, Ling... levels were carried out for Al-Li-S4 alloy, and the creep behavior and the effects of pre-deformation on mechanical properties and microstructures were determined under basic thermodynamics conditions......
MPa, ultimate tensile strength of419 MPa and elongation of 15.8%. The processing route involves extrusion, pre-deformation and aging,which leads to a bimodal structure and nano-precipitates. Back-stress originated from the deformationincompatibility in the bimodal-structure alloy can improve ductility. In addition, dislocation density in coarse grains increased during the pre-deformation strain......

that coupling the deformation stored energy with a special interpolation function is incorporated. Both the deformed grain topology and the deformation stored energy have been included in order to investigate the influence of pre-deformation on the subsequent austenite SRX at different hot deformation levels. Diverse scenarios of microstructure evolution show different deformation-dependent recrystallized......
