Abstract

The enthalpies of formation of amorphous Zr-Cu, Zr-Ni, Zr-Cu-Al, Zr-Ni-Al and Zr-Ni-Ti alloys from pure crystalline elements at 298 K were measured in an isoperibolic Calvet-type solution calorimeter which is operating in the temperature range 298–1300 K. The alloys of the following compositions were investigated:

Zr_1-xCu_x (x = 0.30, 0.40, 0.50, 0.60, 0.65, 0.70)

Zr_1-xNi_x (x = 0.33, 0.40, 0.67)

(Zr_0.65Cu_0.35)_1-x (Zr_0.65Cu_0.35)_x (x = 0, 0.10, 0.20, 0.40, 0.50, 0.60, 0.70, 0.80)

(Zr_0.60Ni_0.40)_1-x (Zr_0.60Ni_0.40)_x (x = 0, 0.125, 0.250, 0.374, 0.500)

(Zr_0.33Ni_0.67)_1-x (Ti_0.33Ni_0.67)_x (x = 0, 0.15, 0.30, 0.45)

The results are discussed in comparison with thermodynamic data about enthalpies of formation of liquid alloys and intermetallic compounds available in the literature. In all investigated systems the enthalpies of formation show great negative values and a strong chemical interaction between the atoms.

锆基金属非晶二、三元合金生成焓的实验研究

用等循环calvet型溶液量热计在298 K温度范围内测定了纯晶元素在298 K温度下的非晶态Zr-Cu、Zr-Ni、Zr-Cu- al、Zr-Ni- al和Zr-Ni- ti合金的生成焓。研究了以下成分的合金:Zr1-xCux (x = 0.30, 0.40, 0.50, 0.60, 0.65, 0.70)Zr1-xNix (x = 0.33, 0.40, 0.67)(Zr0.65Cu0.35)1-x (Zr0.65Cu0.35)x (x = 0,0.10, 0.20, 0.40, 0.50, 0.60, 0.70, 0.80)(Zr0.60Ni0.40)1-x (Zr0.60Ni0.40)x (x = 0,0.125, 0.250, 0.374, 0.500)(Zr0.33Ni0.67)1-x (Ti0.33Ni0.67)x (x = 0,0.15, 0.30，0.45)将所得结果与文献中有关液态合金和金属间化合物形成焓的热力学数据进行了比较。在所有被研究的体系中，生成焓都表现出很大的负值和原子之间强烈的化学相互作用。
