Abstract
Strain hardenable materials achieve their strength due to the build-up of defects and dislocation tangles within the microstructure brought about by induced strain through processing or forming. This strength can be significantly reduced and negatively impacted if the material is used in service at elevated temperatures which causes the grain structure to recover and recrystallize to a more organised lower strength state. Forming limit curves of C106 DHP Copper and 316L Stainless steel were established using an Interlaken hydraulic press with Nakajima punch tooling and GOM DIC cameras. These formed samples were used as an analogue to current formed parts, the effect of extant elevated operating temperatures was then investigated by means of micro hardness testing. High resolution EBSD using a JEOL JSM-7800F FEG-SEM was employed to understand the various mechanisms responsible for the physical and microstructural changes during forming and at elevated temperatures.
