Abstract
The present invention relates to the addition of niobium to iron based glass forming alloys and iron based Cr—Mo—W containing glasses. More particularly, the present invention is related to changing the nature of crystallization resulting in glass formation that may remain stable at much higher temperatures, increasing the glass forming ability and increasing devitrified hardness of the nanocomposite structure.
