Talk:Charpy impact test

Untitled

Need to add some stuff here...its going on my to-do list! Any suggestions welcome Sam Lacey 00:11, 18 May 2007 (UTC)

Can anyone please verify the origins of this test. I have heard from numerous sources that the test was bought into operation after the Titanic sunk. I believe it was to make sure that the steel used in future vessels would be strong enough to withstand pressure at certain levels. It would be interesting to find out.

According to my professor, it was widely adopted after the Liberty ships were splitting in half; a correlation was discovered such that a particular result on the charpy v-notch test would ensure a sufficiently low ductile to brittle transition temperature to avoid the ship-splitting problem. Unfortunately, I don't have a source on that, and it isn't even the origin of the test, just the origin of its popularity. siafu (talk) 21:45, 21 November 2007 (UTC)

Revert by Bronsonboy

I reverted the page to the last version that existed before vandalizing. No constructive non-bot edits were made in between the vandalism and my reversion, but the fact that the page has been targeted twice in the past month by different people and not reverted promptly is worth noting for the convenience of those checking for vandalism. Any edits that reduce the page size significantly from the current revision are probably vandalism; there is nothing large that should be deleted anytime soon.

Charpy Vnotch impact test

The article cited the Charpy V notch impact test but it does not mention that certain specifications once called for 3mm and 5mm U shaped notches. This was between 1972 and 1980. My source material is personal as I performed tests using all three types of notch at various room and sub -zero temperatures for 8 years amongst other destructive tests on an industrial scale in a test house for a HFSS tube factory. The article gives the impression that only a 2mm V notch was used and I felt I had to point that out. Cheops.23456
