A Case Study: Electrically Assisted Stress Relief Annealing for Cold-Coiled Helical Automotive Springs [PDF]
MaterialsThis study experimentally investigated electrically assisted (EA) stress relief annealing for cold-coiled commercial automotive springs. In EA stress relief annealing, the temperature of a spring is rapidly increased to the annealing temperature (400 °C) and is held constant for a specified time using a pulsed electric current.

Effect of stress-relief anneal time on residual stress of Co-Cr-Mo parts manufactured with selective laser melting [PDF]
MATEC Web of Conferences, 2022 Thermal inconsistencies inherent in the selective laser melting manufacturing process generate residual stress that may exceed the yield strength of the material resulting in deformation and cracking of components. This may however be mitigated through a
