A hot compression testing apparatus for the study of isothermal forging
Abstract
An apparatus for uniaxial compression testing has been developed to simulate isothermal forging conditions. The system can apply 100-kN loads at temperatures up to 1200 + or - 3 C in a controlled environment and at constant true strain rates between 0.00001/s and 1/s. Results on the flow behavior of nickel-base superalloy compacts and composites are presented that demonstrate the importance of control of the testing parameters. The difference in flow strength of the two materials under identical testing conditions is discussed.
