摘要	This study was aimed in the mechanical properties exploration of warm incremental forming of a newly developed 2060 aluminum-lithium (Al-Li) alloy. One method of oil heating was utilized in this article. Following the tensile and hardness tests of the components, it could be obtained that the tensile strength and hardness of the incremental forming component decreased with increasing the temperature and increased with increasing the feed rate. Meanwhile, the tensile strength and hardness of the component manufactured at 120 degrees C and 160 degrees C were higher than the base material, due to strain hardening. Dynamic recovery existed in the component manufactured at 200 degrees C and dynamic recrystallization existed in the component manufactured at 240 degrees C. Also, the results were in a good agreement with the optical micrograph microstructure and the tensile fracture morphology. The tensile fracture mechanism of the component manufactured at 120 degrees C was mainly brittle fracture. In contrast, the tensile fracture mechanism of the component manufactured at 200 degrees C and 240 degrees C was ductile fracture. In addition, the accurate prediction models of the component mechanical properties with different forming temperatures and feed rate were obtained through response surface analysis.
