Problems Analysis and Solution of Compression Test with Hydraulic Wedge for Gleeble-3500 Thermal Analogue

There have been some problems of Gleeble-3500 thermal analogue when replacing the hydraulic wedge for compression test including that the strain rate and strain capacity could not meet the requirement of set-up procedure, and the specimen appeared inhomogeneous deformation and drum sharp. The above problems were analyzed and handled. The results showed that the matters can be improved by adjust the force between the jaws and the specimen, fill the argon protect air in the work cavity, modify the deformation procedure and keep suitable lubricant at the interface between the anvils and the specimen.
