Influence of Prior Heat and Creep on Fatigue in Structural Elements of DTD 5014 (RR58) Aluminum Alloy

摘要

Effects of heat on fatigue have been studied by fatigue tests at ambient temperature on specimens first subjected to a single period of heating with and without steady load applied. The tests employed constant amplitude loading on various structural elements in DTD 5014 (RR58) aluminium alloy material. Heating was applied at temperatures in the range 100 C to 170 C for times ranging from lh to 20000h.
