Abstract This study investigated the stress relaxation and fatigue life strength of laser-peened single-crystal nickel superalloy specimens compared to unpeened shot-peened following hot corrosion exposure then testing. The were treated by conventional laser peening a new cyclic plus thermal microstructure engineering process. latter treatment supports benefit unique process involving applicati...

The mechanism of AgCl-induced stress corrosion cracking Ti-6246 was examined at 500 MPa and 380 °C for 24 h exposures. SEM STEM-EDX examination a FIB-sectioned blister crack showed that metallic Ag formed migrated along the crack. TEM analysis also revealed presence SnO2 Al2O3 products mixed into TiO2. fracture surface has transgranular nature with brittle appearance in primary α phase. Long, s...
