采用合金设计方法，制备了原位生成α-Fe枝晶增强Fe_（77）Mo_5 P_9 C_7 B-5（1）（5）大块非晶复合材料。与通常脆性断裂的铁基大块非晶相比，该复合材料具有大于30%的塑性应变和大于3.0 GPa的断裂强度。韧性α-Fe枝晶的原位形成是塑性显著增强的原因（C）2009 Acta Materialia Inc Published by Elsevier Ltd All rights reserved
Using alloy design, an Fe77Mo5P9C7 B-5(1) (5) bulk metallic glass matrix composite reinforced by in situ formed ductile alpha-Fe dendrites has been developed In contrast to the monolithic Fe-based bulk metallic glasses that usually Fail in brittle fracture, the resulting composite shows a significant plastic strain of more than 30% as Well as a high fracture strength of over 3 0 GPa. The in Situ formation of the ductile alpha-Fe dendrites accounts for the significant enhancement of the plasticity (C) 2009 Acta Materialia Inc Published by Elsevier Ltd All rights reserved
