本文研究了Al-Pd-Mn系的部分等温相图，目的是确定与化学计量的二十面体（I）相平衡的液相线组成。在3至9at%Mn和18至25at%Pd的范围内，I相作为主相沉淀。在1114 K下平衡到化学计量的I-Al 70 Pd 20 Mn 10相的液体的准确组成被确定为Al 73.5 Pd 19.7 Mn 6.8
A partial isothermal phase diagram in the Al-Pd-Mn system was examined with the aim of determining a liquidus composition which equilibrates with a stoichiometric icosahedral(I) phase. The I phase precipitates as a primary phase in the range of 3 to 9 at% Mn and 18 to 25 at % Pd. The accurate composition of the liquid which equilibrates to the stoichiometric I-Al 70 Pd 20 Mn 10 phase at 1114 K was determined to be Al 73.5 Pd 19.7 Mn 6.8
