Embrittlement Poem by Micron Jan

The cause of failure, I boldly say,
Now which type must I check today?
Perhaps it's hydrogen embrittlement's reign,
Hydrogen unzipping metal grain by grain.

Strain-age embrittlement, I've seen before,
The metal aged and strained, yet I ignore.
Liquid-metal embrittlement? Not quite clear,
Molten metal at boundaries I cannot peer.

Galvanizing embrittlement, maybe?
No, it wasn't galvanized, so I'm free.
But the cause of failure I finally know,
It's brain embrittlement—now on show!
