GLEEBLE – 3800
The “GLEEBLE – 3800” installation is a high-tech complex that allows for physical simulation of welding processes, processes of hot deformation of metals such as forging, rolling, and drawing, and also allows for the simulation of heat treatment of metals with various heating and cooling rates. Hot compression and tensile tests can be performed at either constant or varying force values during the experiment. The temperature and heating rate of the sample can also be varied depending on the experimental task. The maximum short-term compressive force can be 20 metric tons, and the tensile force can be 10 metric tons. The maximum process temperature during such experiments can be 2000ºС. Such experiments give the possibility to determine the degree of deformation depending on the applied force. Hot deformation tests along one direction can be carried out on two different mobile blocks. The universal unit “Gleeble System” is used to simulate physical processes in the case of “simple” compression or stretching.

Technical notes
This complex has quite wide possibilities for regulating the rate of heating and cooling of materials. Using a computer program and also using samples of different types, it is possible, during one test, to conduct heating and cooling at different speeds. Thus, the maximum heating temperature of the metal in thermal mode (i.e. in the absence of mechanical loads) is 3000ºС, and the instantaneous rate of heating and cooling reaches 10000ºC. The “GLEEBLE – 3800” complex has some features for regulating the temperature of experiments. Temperature control is carried out using thermocouples that are welded (or wrapped) to the surface of the samples along the diametrical section in the center of the sample, where an isothermal zone is established. The accuracy of temperature measurement is ±1О ºС, the temperature correction frequency is 50 Hz, and the frequency of registration of values of various parameters can reach 50000 Hz.
