Hot twist test
WebJul 10, 2014 · Hot Twist Test. In a hot twist test, a round bar is twisted in one direction until material failure occurs. The amount of rotation is taken as a quantitative measurement of metal forgeability. This test is often conducted on a material at several different temperatures. Other tests are also used in industrial metal forging manufacture. Websince Sauveur used the hot twist test to determine the optimum temperature for hot working of various steels in 1929 (Ref. 1 ). The direct welding related appli- cation of ductility testing was introduced shortly after the "Gleeble" was devel- oped in 1949 by Nippes and Savage (Ref. 2).
