Beschreibung
Mihai Stoica investigates in details the glass formation of two model alloys, [(Fe0.5Co0.5)0.75B0.2Si0.05]96Nb4 and Fe74Mo4P10C7.5B2.5Si2. More than 20 master alloys using different raw materials were prepared. Besides the typical calorimetry and X-Ray diffraction, magnetic measurements were employed to analyze the amorphicity degree of the sample. Two new bulk metallic glass-forming alloy compositions are designed and possible preparation routes are proposed.
