Bennett Posted December 11, 2007 Author Share Posted December 11, 2007 It means there is a load more nickel than you thought. Hmm. I'm going to dend it to the lab, to get exact chemestry, but it shuldnt be much over 1% nickel. At what % of nickel does it stop sparking? Link to comment Share on other sites More sharing options...
Howard Clark Posted December 11, 2007 Share Posted December 11, 2007 The nickel, and perhaps the other exotics you put in there may stabilize the austenite phase. Nickel alone doesn't suppress sparks, but it does make the austenite stable. Generally considered to be 8% required for a reliable effect, but I doubt it takes that much to stabilize austenite quite a lot. Often with alloying elements, there is a synergy effect that makes a combination of a little of two or three elements much more effective than a lot of one element, savvy ?

Another question, does bainite have the same magnetism as martensite? Thanks. EDIT:Sorry, but I have patent pending. Will repost later.

B. Norris Posted December 12, 2007 Share Posted December 12, 2007 Not sure what that means or what I'm going to do with it. Any ideas? Is adding some, or all, of this piece you made to another smelt an option? That would lower the amounts of each alloying element in the final alloy. I do not know what the typical amounts of niobium used to alloy with are but, what you added seems rather high to me. They must be called HSLA (high strength low alloy) steels for a reason. I have to admit what you are doing is way over my head. But, I have been following it with interest!

Bruce Yes, you are right on. I wanted twice the iron in this melt, but it's ok, since all the rhenium and niobium uptook in the ingot. That means I can re-melt it conventionaly, and add some make-up iron. BUT, since this particular chemestry shows highly unusual charcheristics, I'm going to use some of it up in testing and such. I have enough chems for 2 more runs like this, if I need some type of patent info...... Don't worry, I won't sue anyone BTW, I don't see how this is over your head at all. You know ecactly what alloy group and ingredient amount. That's all I did, and threw a match to it Thanks for the interest. It keeps me going when I have failures, which is often Link to comment Share on other sites More sharing options...
kb0fhp Posted December 14, 2007 Share Posted December 14, 2007 (edited) Don't say I never gave you anything..... Based on the phase diagram, and the expected amounts of alloying elements present - I chose Fe-Ni-Re as the primary, The phase diagram indicates that it would be predominately austenite. Just put me on the patent application (I am just kidding).... fulltext.pdf Edited December 14, 2007 by kb0fhp D.

Bennett Posted December 14, 2007 Author Share Posted December 14, 2007 SWEET! Thanks Doc. Just put me on the patent application Heck yeah!!! Thanks for your time. I couldn't find much of anything on Re in steel. That will save a few chunks I was going to experiment on. Do you think that bugger can be carburized?

kb0fhp Posted December 14, 2007 Share Posted December 14, 2007 I really have no idea - and what the carbon will do to the structure. If I had a copy of JMATPro I could get a reasonable estimate. Perhaps one of your people there can do a run for you... I suspect that the alloy could be a nice strong, possibly high temperature, stainless steel. Looking at the phase diagram, it certainly is a possibility. I would guess that Re would form carbides - but I am not sure. I am trying to find an Fe-Re-C phase diagram, but have had no luck. D.

DJPratt Posted December 15, 2007 Share Posted December 15, 2007 this topic peeked my interest and if you need to i might be able to get a some on a mass spectrometer for you. I used to be the electronics/computer tech for Southern Ill. University Carbondale Department of Geology and i still have some friends i will see on new years. just thought i would offer ~~DJ Link to comment Share on other sites More sharing options...

Sure. That would be very kind. How much, and what form do you need it in? Remeber I threw 2 chunks of 2 different meteorites. This metal is loaded with all kinds of trace elements...that is that survived the thermite reaction. really have no idea - and what the carbon will do to the structure.

I would guess that Re would form carbides - but I am not sure. I am trying to find an Fe-Re-C phase diagram, but have had no luck. I have been offered the use of that program. They hardly ever use it at work. If the Re forms carbides, I'm hoping the Nb will do it's job and take care of any coarse structures???

DJPratt Posted December 15, 2007 Share Posted December 15, 2007 Let me look in to it Harvey wont be in the office till Monday so i will ask then. i never used the equipment that was my buddy Dan's job so i don't know off the top of my head what form or how much it will take. the only question is how much beer dose it take to bribe a grad student and at Carbondale the likely answer is not much .... lol I will let you know as soon as i can find out ~~DJ Link to comment Share on other sites More sharing options...
kb0fhp Posted December 16, 2007 Share Posted December 16, 2007 JMATPro would be able to indicate what phases are thermodynamically probably present, and indicate possible CCT and TT diagrams....Very useful - I wish I had a copy....

kb0fhp Posted December 17, 2007 Share Posted December 17, 2007 Based on the phase diagram - I believe that it is stable Austenite - similar in microstructure to a stainless steel.I would be very surprized if it becomes martensitic.

Yeah, I was waiting for that At least it's my own creation. 3 metalurgists urged me to see a patent lawer asap, after seeing my mistake. Sorry to bail out abruptly like that. Kind of whent against my grain. I like to share, much to the shagrin of many folks. Edited December 19, 2007 by Bennett Link to comment Share on other sites More sharing options...

The nickel spected out to .23% http://www.bladesmithsforum.com/index.php?showtopic=10420 EDIT: I need to correct my subtitle. It's totally stable austenite. Not metastable.
