Norseman; welcome to the wonderful world of metallurgy! Here are some websites which I have found useful in my study of this fascinating subject.
First; be aware of the 'knowledge base' section on the first page of the BFC website. In this knowledge base, you will find lots of very good, well presented data. Joe Talmadge's 'Steel FAQ's' are absolutely required reading.
Second, there is a very good, comprehensive glossary of metallurgical terms here:
http://www.metal-mart.com/dictlist.htm
Third, this is the mother board of internet websites with metallurgical information:
http://www.mlc.lib.mi.us/~stewarca/metallurgy.html
Fourth, this is a good site if you wish to find out the composition and characteristics of a specific alloy:
http://www.principalmetals.com/
Principal Metals also has a wealth of other information at this site. Things like a glossary, metric conversion table, hardness conversion tables, and the Periodic Table.
Hope this helps, and if other posters have favorite sites, please post them; I am always on the lookout for good websites. Walt
