Abstract
The invention discloses an electric auxiliary single tensile test temperature control device and a method for controlling the temperature uniformity of a sample in a test process. The control device comprises a power control cabinet, a first high-temperature-resistant insulating tape, a second high-temperature-resistant insulating tape, a first constant DC power supply, a second constant direct current power supply, a first clamp, a second clamp, a first ceramic heating sheet, a second ceramic heating sheet and an air blower. According to the technical scheme of the invention, temperature of the junction of the sample and the clamp can be increased, the temperature distribution gradient of the sample is further reduced, the temperature of the sample in electric auxiliary single tensile test can be controlled uniformly, the sample deformation is uniform, the deformation flow behavior of a material is described more accurately, and deformation concentration caused by non-uniform temperature distribution due to the heat transfer problem between the sample and the clamp in the traditional design is avoided.
Description
technical field [0001] The invention belongs to the technical field of basic testing of plastic forming performance, in particular to an electric-assisted single-pull test temperature control device and its use method in the process of studying the electroplasticity of sheet metal, which can be used to study the law of the influence of electric field on the forming performance of sheet metal , to reveal the mechanism of the influence of electric field on the flow behavior of materials. Background technique [0002] In the industrial field, lightweight can directly reduce fuel consumption, reduce exhaust emissions, and improve efficiency. Therefore, various industries have put forward urgent requirements for lightweight. Excellent properties such as high strength and corrosion resistance are widely used in aerospace, automobile and other fields. However, its plastic formability at room temperature is poor and its forming window is small, which limits its application. Studie...
