SHAO Yuanzhi;GU Shouren;CHEN Nanping Tsinghua University; Beijing. BORON DISTRIBUTION IN BCCINTERMETALLIC COMPOUND Fe_3(Si,Al) AND IMPROVEMENT ON ITS BRITTLENESS. Acta Metall Sin, 1991, 27(2): 27-32.
Abstract Studies were made of the influence of B distribution in bcc lattice in-termetallic compound Fe_3(Si, Al) on the long range order and the improvement onits brittleness. A new mechanism concerning weakening of grain interiors is put for-ward. Based on this mechanism, the brittleness improvement of the bcc intermetallicswith B addition could be well explained.
