>From an earlier post,
 
?[Widmanstatten patterns] can happen in wrought iron alloys used for
heat treating fixtures, aluminum alloys, copper alloys and very commonly
in titanium alloys. It can also happen in HSLA alloys when improperly
heat treated.?
 
While I personally don?t have any pictures, I Googled it and came up
with these:

You said it was incorrect to state that only meteorites exhibited a
Widmanstatten pattern.
 
What other materials exhibit a Widmanstatten pattern?
 
Do you have pictures?
