本文指出,经过液态急冷处理,Fe-12.6at.-%B合金形成由非晶、α-Fe及未知亚稳相组成的淬态组织;在进行加热时,淬态转变为α-Fe及Fe_2B;压力对以上相变过程有显著影响,高压下未知亚稳相的温区变宽并形成DOe型Fe_3B.

The liquid-quenched structure of Fe-12.6 at.-%B alloy was identified to becomposed of the amorphous,α-Fe and an unknown metastable phase,which willtransform into a mixture of α-Fe and Fe_2B during heating under normal pressure.The remarkable effect of high pressure on the phase transition process of such alloylies in the extension of temperature range in which the unknown metastable phasewill exist and the formation of DOe——type Fe_3B.
