The equivalent strains involved in hot rolling processes are usually in excess of 2. Additionally, hot deformation is executed at temperatures higher than 60% of the absolute melting point and strain rates ranging from 1 to 100s(-1). When studying hot deformation, it is important to experimentally achieve such temperatures, strains and strain rates. Mechanical testing is ordinarily employed as means of performing these studies. Compression, either axial or plane strain, is, however, limited to relatively small total strains. The maximum strain rates obtained in such tests are also restricted to similar to10s(-1). Hot torsion, an alternative frequently used to simulate hot rolling, can achieve higher strains. The strain rates usually reported in the literature, however, are mainly constrained to the range of 1-10s(-1). This paper presents a simple experimental technique that can be used to obtain higher strain rates in torsion testing, achieving values up to 100s(-1).
