[TheForge] spring temper for brass question

[theforge@mailman.qth.net]

To All,
Tempering is a term that should be pretty much limited to a discussion about 
the heat treatment of steel.  Yes, there are other "temper" designations but 
they are most often achieved by cold work in the form of rolling or wire 
drawing for non-ferrous alloys.  Aluminum alloys have temper designations but they 
are the result of solution treating and then aging.  Some are followed by cold 
work.
Pity the poor metallurgist who for all of his life was knew that austenite 
was soft and martensite was hard only to be thrust into the world of Nitinol 
where austenite is hard and martensite is soft.  
Now y'all just be careful about what terms you use to describe what you are 
doing.
