| 1 | Evolution of microstructure in semi-solid slurries of rheocast aluminum alloy显示文摘Semi-solid metal processing is being developed in die casting applications to give several cost benefits.To efficiently apply this emerging technology, it is important to understand the evolution of microstructure in semi-solid slurries for the control of the rheological behavior in semi-solid state.An experimental apparatus was developed which can capture the grain structure at different times at early stages to understand how the semi-solid structure evolves.In this technique, semi-solid slurry was produced by injecting fine gas bubbles into the melt through a graphite diffuser during solidification.Then, a copper quenching mold was used to draw some semi-solid slurry into a thin channel.The semi-solid slurry was then rapidly frozen in the channel giving the microstructure of the slurry at the desired time.Samples of semi-solid 356 aluminum alloy were taken at different gas injection times of 1, 5, 10, 15, 20, 30, 35, 40, and 45 s.Analysis of the microstructure suggests that the fragmentation by remelting mechanism should be responsible for the formation of globular structure in this rheocasting process. | R.CANYOOK S.PETSUT S.WISUTMETHA NGOON M.C.FLEMINGS J.WANNASIN | 2010 | Transactions of Nonferrous Metals Society of China2010，20，9： | 11 |
