Breech Block Failure 1916/1920 Erfurt

[STEINBVG]

If i understand correctly metal fatigue accumulates with multiple bangs over period of time, correct? The shooting/use are the main culprits.

Is there any damaging structural chemical/physical process in an old gun's metal [ or any metal/alloy] even without any shooting or physical use?


LET'S SAY THE SAME METALLURGY, FORGING , TOOLING, MACHINNING- THE IDENTICAL 2 GUNS MADE A 100 YEARS APART. NEVER SHOT. IS THE OLDER ONE MORE LIKELY TO BREAK SIMPLY FROM AGING?

In theory the older gun is more susceptible to breakage due to the fact that metal crystalizes over age but in practice the amount of possible crystallization over 100 years would be considered negligible.
