Talk:Amorphous metal

From Wikipedia, the free encyclopedia

[edit] Reheating

The article asserts that upon reheating amorphous metals start to flow. I believe that this is slightly misleading, it is a well known phenomenon that heating amorphous metals will cause them to recrystallise, at least in part, and take on the more stable form, i.e. a crystal. Where did the concept of reheating the glass to make it flow come from? 129.78.64.106 01:42, 12 October 2006 (UTC)

Well, upon heating above a temperature Tx, amorphous metal recrystalize, but there is a temperature "window" below Tx that metalic glass can flow. This window is Tg < T <Tx, where Tg is the glass transition temperature.

This effect is well known, See: "Effect of die-casting parameters on the production of high quality bulk metallic glass samples" By Laws, Gun & Ferry. 129.78.208.4 04:41, 14 March 2007 (UTC)
