| 12 | BUTTERFLY MARTENSITE NUCLEATION IN AN Fe-Ni-V-C ALLOY显示文摘The butterfly martensite nuclei in an Fe-Ni-V-C alloy were observed under TEM,they con-sist of enveloping dislocations with Burger’s vector(1/2)[(?)]fcc and arrays of dislocationswith Burger’s vector(1/2)[(?)10]fcc piled up within the former.The enveloping dislocationsand the arrays of dislocations provide the required shear when the planes((?)11)fccmove witheach other to alter their stacking order and change into the planes(110)bcc respectively.Thenecessary adjustment of the spacings is provided by the dislocations in martensite.Thecrystallographic relationship after double-shear is K-S one. | CHEN Qizhi WU Xingfang KE Jun (T Ko) University of Science and Technology Beijing,Beijing,China | 1991 | Acta Metallurgica Sinica(English Letters)1991，4，6： | 0 |
