I am not a metallurgist! I had people working with/for me who really understood this stuff! All I knew was that hydrogen embrittlement was BAD NEWS! I imagine it caused structural change, very important when hardness (self tappers, thread formers HT bolts etc) was important.
What was of note was that eg screw heads popped off several hours after installation when the fastener had been put under load. I don't recall them breaking up in the box! So on spokes I would think that breakage would be pretty soon after installation/use under load.
