New experimental apparatus coupling loading, heating and magnetic field

The principle and structure of a characteristic apparatus designed and made by authors were introduced, which coupled loading, heating and magnetic field, by using it the study of plasticity and superplasticity of materials under both effects of heating and magnetic field can be easily carried out. The peculiarity of the apparatus is that the deformed specimen in a furnace twined by exiting coil was heated and sealed by introducing an inert gas with high purity, certain temperature and certain pressure, which realized heating outside furnace and dynamic sealing. The former eliminated the interference of magnetic field produced by usually applied heating circular resistance wire on the magnetic field produced by exiting coil, and the latter removed the friction between loading bar and furnace mouse, which realized exact measurement of the effects of magnetic field, loading force and loading rate on deformation behavior of materials.
