Ultrasonic welding of lap joints of PEI plates with PEI/CF-fabric prepregs by Vladislav Alexenko, Defang Tian, Sergey Panin, Svetlana Bochkareva, Iliya Panov

“…In this case, rising the USW time from 400 up to 800 ms radically changed the macrostructure of the fusion zone, while the strength properties did not vary significantly (shear stresses were 42–48 MPa). Computer simulation of the influence of the PEI/CF-fabric ratios in the prepregs on the deformation response of the USW joints showed that the prepreg thicknesses and, accordingly, the PEI/CF ratios did not exert a noticeable effect on the strain–stress (tensile) diagrams, while the determining factor was the adhesion level. …”

Strength–ductility synergy in Mg-Gd-Y-Zr alloys via texture engineering in bi-directional forging by Jingli Li, Quanfeng Han, Xiuzhu Han, Xin Yi

“…Roles of the double-peak basal texture in overcoming the strength–ductility trade-off include promoting non-basal slip, increasing ductility, and enlarging the Hall–Petch effect along the sample elongation direction while reducing the extent of anisotropy in critical resolved shear stresses of different slip systems. This study demonstrates that texture engineering is a powerful strategy to control magnesium alloy performance and BDF is a promising processing technique for enhancing mechanical properties of magnesium alloys.…”
