Is there any distinguishing features to identify and contrast between corrosion "assisted" fatigue and corrosion "initiated" fatigue in Al alloys?

I am lookng into a problem that require seperation of this two mechanisms through factographic features and/or microstructural characterization.

What could be the factors (other than SCC) responsible for GB embrittlement in an Al-Cu-Mg-Ni-Fe base AA2618 alloy?

The alloy having very coarse Al9FeNi and Al7Cu2Fe types of second phase distributed (at both grain boundaries as well as inside grains) in an equiaxed matrix grain structure. Apparently no...

Can anybody suggest suitable literature for thermodynamic energy parameters for carbides (e.g., MC, M6C, M23C6) in Ni-base super alloys?

Need this THD data for analyzing the stability of these carbides at different temperatures.
