| 3 | Structural Changes ofαPhase in Furnace Cooled Eutectoid Zn-Al Based Alloy显示文摘Furnace cooling is a slow cooling process. It is of importance to study structural evolution and its effects on the properties of alloys during the furnace cooling. Decomposition of aluminium richαphase in a furnace cooled eutectoid Zn-Al based alloy was studied by transmission electron microscopy. Two kinds of precipitates in theαphase were detected in the FCZA22 alloy during ageing at 170℃. One was the hcp transitionalα″m phase which appears as directional rods and the round precipitates. The other was the fccα′m phase. It was found that the transitional phaseα′m grew in three preferential directions of <110>, <011> and <101>. The orientation relationship between theαphase and transitional phaseα′m was determined as (022)α′m (fcc)//(022)α(fcc), [111]αA′m(fcc)//[233]α(fcc). The non-equilibrium phase decomposition of theαphase is discussed in correlation with the equilibrium phase relationships. | Y.H.Zhu K.C.Chan G.K.H.Pang T.M.Yue W.B.Lee | 2007 | Journal of Materials Science & Technology2007，23，3： | 0 |
