Investigations of Surface Dissolution on Fatigue Crack Nucleation in Ni-22Cr-2Fe Alloy
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 5
Abstract
Ni-Cr-Fe alloy specimens were fatigued in a hydrochloric acid solution cell at pH 5.6 ±0.1. Results show that the number of surface slip bands forming, extending, and widening increased with the number of cycles. Results also indicated that, initially, cracks initiated as transgranular features but took on intergranular forms as the number of cycles increased.
