[交流] 目前为止晶化温度最高的非晶合金是?

带材也好,块体也罢,哪种晶化温度最高?

晶化温度和加热的速率有关,速率越快,温度越高!

(Received 22 March 2005; accepted 12 May 2005)
Mechanically alloyed Mo44Si26Ta5Zr5Fe3Co12Y5 multicomponent glassy alloy exhibits an exceptionally high glass transition temperature of 1202 K and a crystallization temperature of 1324 K, as well as an ultrahigh hardness of 18 GPa. This example is used to demonstrate metallic glasses that possess extraordinary thermal stability and ultrahigh strength and, at the same time, a wide supercooled liquid region (122 K) that is needed for processing into bulk forms through powder metallurgy routes.
