Cold drawing process is one of the most used metals forming processes in industries for forming seamless tubes. This process of plastic deformation of metals occurs below the recrystallization temperature and is generally performed at room temperature. When metal is cold worked, upon the release of forming force, the springback occurs. In this paper, the springback effect of the seamless tube t...
Abstract Warm forming has been shown to be an effective way increase the formability of various aluminum sheet alloys. If applied precipitation hardenable alloys, aging and/or coarsening may occur during heating processes. As such, there is a potential leverage warm process artificially age In this study, characteristics pre-aged Al-Mg-Si-Cu alloy (designated AA6013-PA and comprising 4 h, 100 °...
light-weight and high strength alloys such as al-mg alloys are used in order to reduce the weight of industrial components. however these materials should be formed at elevated temperatures due to their poor formability at room temperature. hot metal gas forming is one of the high-tech forming processes that is used to solve this problem. recent investigation on tube hydroforming showed positiv...
Tube spinning is an effective plastic-forming technology for forming light-weight, high-precision and high-reliability components in high-tech fields, such as aviation and aerospace. However, cracks commonly occur in tube spinning due to the complexity of stress state, which severely restricts the improvement of the forming quality and forming limit of components. In this study, a finite elemen...
hot rolling of a large ring of titanium alloy (lrt) is a highly nonlinear incremental forming process with coupled mechanical and thermal behaviors (mtbs) which significantly affect microstructure and properties of the ring. the feed rate of idle roll and the rotational speed of driver roll have major effects on ovality of the ring. in this paper, the effects of these parameters on the ovality ...
