METHOD FOR PREDICTING AND EVALUATING FORMATION OF BULK METALLIC GLASS IN MULTICOMPONENT METALLIC ALLOYS

摘要

The present invention provides compositions bulk amorphous form in the forecast and the assessment using the new amorphous-forming ability evaluation factors which may be facilitated component alloy composition of easily Bulk-forming region by combining the arguments presented in the thermodynamic point of view and dynamic perspective on the amorphous form and to a method of prediction and evaluation range. ; The invention of each of the system configuration element to the first temperature zone and comprising the steps of: coupling a second temperature range been presented in the dynamic point of view, the combined first and second temperature intervals been proposed in thermodynamic point of view relates to an amorphous form and step by standardizing (normalizing) to the t _m^mix calculated in consideration of the melting point and amount to obtain the amorphous forming ability evaluation factor (ε) value, the maximum thickness of the bulk amorphous form using the amorphous forming ability evaluation factor (ε) value (t _max ) to obtain characterized in that it consists of the steps: ; Bulk formation forecasting, assessment factors, the thermodynamic point of view, dynamic perspective
