摘要
The AlxMg(1-x)B2 solid Solution was studied at temperatures of 900, 1000, 1200 and 1400 degrees C using X-ray diffraction. From the obtained data, isothermal sections at 1000, 1200 and 1400 degrees C have been proposed for the Al-Mg-B ternary system. Based oil these results there exists an equilibrium between Al and AlMgB14 at temperatures above 1000 degrees C.
