Abstract

The temperature rise at the tip of dynamically propagating cracks in Beta-C titanium is measured using an array of high speed infrared detectors. For a crack propagating at 396 m/s the maximum crack tip temperature rise is 450°C. This is high enough that the mechanical properties of the material at the crack tip will be changed, thus affecting the fracture process in a significant manner.
