Tribological and texture analysis in Twin-roll casting 2060 Al-Li alloy
In this work, the wear behaviors of a 2060 Al-Li alloy prepared by the twin-roll casting (TRC) process was analyzed and supplemented with coupling simulation calculations. As the load increased from 2 N, 5 N, 10 N, and 20 N at room temperature, the friction coefficient decreased due to the oxidation...

| description | In this work, the wear behaviors of a 2060 Al-Li alloy prepared by the twin-roll casting (TRC) process was analyzed and supplemented with coupling simulation calculations. As the load increased from 2 N, 5 N, 10 N, and 20 N at room temperature, the friction coefficient decreased due to the oxidation lubrication triggered by heat accumulation, which was calculated via the simulation; the wear volume decreased; and the decrease in wear volume rise rate was a result of dynamic recrystallization and grain rotation. Observing the grain rotation and analyzing the texture evolution law during wear tests with scanning electron microscopy (SEM) and electron back-scattered diffraction (EBSD) was an innovation. To support the rotation behavior, a method for calculating the Schmid factor of rotating grains was developed. As the load rose, the R-Cube {001} 〈110〉 texture rotated to the rotating cube {001} 〈310〉 texture towards the α-fiber line. The modification decreased the maximum Schmid factor along the sliding and rolling directions, indicating an increase in initial strength and wear resistance. In addition, at a 2 N load, the TRC-3 sample with higher substructure and deformation texture exhibited less wear volume than the TRC-6 sample. |
