| 1 | Stress-Induced Martensitic Transformation of Zr_(50)Cu_(25)Ni_(10)Co_(15) Nanocrystals Embedded in an Amorphous Matrix显示文摘The stress induced martensitic phase transformation of spherical ZrCu nanocrystals embedded in an amorphous matrix was studied in this paper. Microstructural observations revealed that the martensitic transformation of the nanocrystal was hindered by the surrounding amorphous coating. The existence of two-step transformation from the austenite phase(B2) to the base structure martensite(B19') and finally to the most stable superstructure martensite(Cm) was also demonstrated. The Cm martensite with(021) type I twinning symmetrically accommodation was surrounded by the B19' martensite with dislocation morphologies. | W.H.Gao X.Y.Yi X.L.Meng G.Song W.Cai L.C.Zhao | 2017 | Journal of Materials Science & Technology2017，33，3： | 0 |
