Evaluation of the Macroscopic Formability of Metallic Accoutrements Using a Cylinder Contraction Test

John Roughe

Several inflow features revealed by hot cylinder contraction tests are macroscopically anatomized and compared.Accoutrements including AISI 1025( 100 – 500°C), AISI 52100( 900 – 1200°C), AA6082 (20 – 300°C and 350 – 550°C), Ti- 6Al- 4V (500 – 800°C) and AZ61A (250 – 400°C) were grouped in terms of formability. The shapes of cylinder- compressed samples were anatomized and related to formability. The addition of the maximum compass increase near themid-plane and the averaged minimum compass increase at the two instance- tool interfaces, i.e., the “cylinder contraction evaluation factor” (CCEF), serves as an indicator of formability [1]. To quantify the effect of temperature on formability, several criteria were used, including the CCEF and temperature softening formability indicator (TSFI). It has been shown that the CCEF and TSFI've mileage for assessing the formability of tested accoutrements and that temperature softening greatly affects the formability of metallic accoutrements [2].
