A force-applying device for strip annealing experiments

Abstract

The invention provides a force application device for a strip annealing experiment. According to the technical scheme, the left end of a connection rod (2) is in threaded connection with a left clamping device (1), the right end of the connection rod (2) movably penetrates through a right clamping device (4), a first spring (3) is assembled between the right shoulder of the connection rod (2) and the right clamping device (4), a nut (6) is assembled at the right end of the connection rod (2), and a second spring (5) is assembled between the nut (6) and the right clamping device (4). The left clamping device (1) is formed by connecting two clamping blocks through a bolt, wherein both of the two clamping blocks are strip-shaped. A bulge is arranged in the middle of a pressing surface of one strip-shaped block, and a slot matched with the bulge is formed in the middle of the pressing surface of the other strip-shaped block. A threaded hole is formed in the center of the bulge, and 1-2 through holes are formed in planes of two sides of the threaded hole symmetrically. The force application device is simple in structure, low in cost and convenient to operate, is suitable for applying tension on a strip-shaped metal sample or a metal sample with two ends processed in a strip shape, the set tension F of the metal sample is equal to the tension applied practically on the metal sample.

Description

technical field [0001] The invention belongs to the technical field of auxiliary devices for strip annealing experiments. Specifically, it is a force applying device used for strip annealing experiments. Background technique [0002] The traditional annealing treatment is to apply a temperature field to the deformed metal, so that the atoms whose own energy is raised can overcome the elastic force field and electrostatic field inside the deformed metal under the action of the temperature field and return to the equilibrium position with the lowest energy through diffusion. , that is, recrystallization. In the recovery and recrystallization process, the application of temperature field and other external fields such as force field will also change the elastic force field and electrostatic field inside the material, thus affecting the diffusion behavior of atoms and the relationship between solute atoms, dislocations and grain boundaries. The recrystallization structure will...
