摘要：

By using a Al2O3 cell coated with Si3N4, the melting point (T-m) of the cast bulk amorphous samples were measured on DTA curve.,; cooled from the molten state. Based on the T. 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 4070 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.
