This application discloses an ultra-high strength, lightweight Al-Ti-V-Cr medium-entropy alloy in the field of medium-entropy alloy materials technology. The alloy comprises, by mass percentage: Al: 24–28%; Ti: 45–50%; V: 10–14%; Cr: 10–14%; and the total content of impurity elements is ≤0.01%. This technical solution obtains a medium-entropy alloy by mixing the four elements in a certain proportion, giving it characteristics such as ultra-high strength, low density, high temperature resistance, and excellent hot workability.

The utility model discloses a heat setting device for a nanometer fishing net, belongs to the field of production and manufacturing, and aims to solve the problems that the stretching lengths of all parts are not uniform due to the influence of the thickness of the fishing net when the fishing net is heated and stretched, and when the stretching lengths are not uniform, the most direct influence is that the thickness of the stretched fishing net is not uniform. The thin part is even broken after being stretched; by arranging the press-fit column, the flattening frame, the flattening wheel and the press-fit plate, a fishing net can be immediately pressed after one-time stretching during heat setting, the surface flatness of the fishing net can be higher through press-fit, the thickness of the fishing net can be more uniform, press-fit treatment is immediately carried out after one-time stretching, and the production efficiency of the fishing net is improved. And the working efficiency is improved, and the thermal forming effect is better.
