The system was also equipped with an inverse analysis module having crucial significance for interpretation of results of compression tests at temperatures close to the solidus level. One of the advantages of the solution is the negligible volume loss of the deformation zone due...

...) through single hit compression testing. The hot compression tests were carried out at two different temperatures ( 850 ° C and 1150 ° C ) applying a range of strain rates ( 0.001 – 0.1 s − 1 ) . The results indicated a greater deformation resistance at higher strain rates. The detected broad stress peaks...
