Can we use the ASTM G48 test to establish the maximum allowable temperature of a metal or alloy in an oxidizing environment like seawater?
This post discusses how the ferric chloride electrolyte of the ASTM G48 test compares with other oxidizing environments such as seawater.
Very interesting article by Haynes Int. on nickel alloys: LINK.
SCC of AZ31B alloy was studied in NaCl solutions at different potentials and chloride concentrations using the slow strain rate technique. A combination of pre-exposure tests followed by immediate straining or straining after a dry air exposure delay helped to weight the relative importance of anodic damage accumulation versus increased hydrogen charging during open-circuit potential pre-exposure. The dependence of ductility with pre-exposure time and the fracture surface of embrittled samples suggest that hydrogen embrittlement of AZ31B was controlled by hydrogen diffusion.
