Manufacturer: Dynamic System Inc. Model: GLEEBLE^© 3500-GTC

Description:

The GLEEBLE© 3500-GTC is a thermal-mechanical physical simulator and dynamic research system that can simulate a wide variety of thermal-mechanical metallurgical conditions. In a GLEEBLE^© 3500-GTC samples of material are heated and mechanically worked while various performance parameters of interest are measured and recorded for analysis. The GLEEBLE^© 3500-GTC  features a high-speed heating system, a servo-hydraulic system and a computer control and data acquisition system. With its high-speed heating and wide range of mechanical capabilities, the Gleeble 3500-GTC is ideal for weld HAZ simulations, nil-strength, thermal cycles, heat treatment studies, low-force tests, hot tensile tests, high-speed compression, multi-hit hot deformation tests, melting, solidification, and strip annealing simulations. Direct resistance heating provides the ability to reproduce the wide variety of thermal profiles that materials undergo in actual processes.
