Abstract
By using a Al2O3 cell coated with Si3N4, the melting point (Tm) of the cast bulk amorphous samples were measured on DTA curves cooled from the molten state. Based on the Tm data, the partial liquidus surface of Zr–Cu–Al ternary alloys was determined. A ternary eutectic point is located around Zr50Cu40Al10, and low melting temperatures of less than 1273 K were obtained in a wide compositional area of 40–70 at%Zr, 30–60 at% Cu and 0–10 at%Al. Bulk amorphous alloys in Zr–Cu–Al ternary system were produced by an arc-casting method and the highest tensile strength of 2000 MPa was observed in Zr50Cu40Al10.Keywords
