I'v brought up this topic before, shoptalkforums, PP and I think here, but have never gotten a finished result/direction. I know that the topic is filled with proprietary beliefs, but there must be some good experience here or a source of reference to expand our knowledge.
Thanks, L. McChesney |

QUOTE(cnavarro @ Apr 14 2004, 05:11 PM) ... we ended up having to machine a set of ductile iron liners after they had been cryo'ed. We ended up destroying every single liner and some of our tooling. It's made me a believer. Any 105mm Nickies receive cyro'ing before plating! so you're using your experience with iron liners to conclude it's effective on aluminum ? how is that even close ? cryo works in ferrous materials due to the whole Martensite/Austenite/Pearlite carbide thing - what's the mechanism in aluminum alloy that makes it work ? and what kind of similar A/B tests did you try on aluminum ? ductile iron and aluminum alloy are just about as close to apples and oranges as i can imagine ... |
