Trans. Nonferrous Met. Soc. China 22(2012) s579-s584 HR-TEM and FIB-SEM characterization of formation of eutectic-like structure from amorphous GdAlO3-Al2O3 system Y. H. HAN1, Y. HARADA1, J. F... that of the ordinary eutectic microstructure solidified from the GdAlO3-Al2O3 system. Therefore, the observed structure is termed "eutectic-like" for distinction. The microstructures formed from......
the macrosegregation in solidified high-silicon aluminum alloys, refine the primary Si particles and finally provide a eutectic-like structure. The morphology of primary Si phase changes from long rod to block, and then to large block clusters when both the excitation current and rotational frequency of RMF increase, meanwhile, the eutectic Si phase changes from long needle to wormlike particles......
boundary by diffusion reaction, the eutectic-like structure and the product of precipitation reaction will disappear. The configuration of TiC particle can’t transform under the test condition......

eutectic-like structure in a Zn-rich Zn-3.37%Cu peritectic alloy processed by Bridgman solidification [J]. Scripta Materialia, 1998, 39(1): 7-11. [4] MA D, LI Y, NG S C, JONES H. Unidirectional... was carried out in the air at 400 ℃ for 12 h to eliminate the microstructure segregation. Figures 1 and 2 display the pristine microstructure composed of white equiaxial ε phase, bone-like TiZn15 phase......
, the characteristic solidification phases formed are as follows: FCC γ-Ni solid solution; MC and/or MC6 type niobium carbides; eutectic-like Laves phases enriched in Nb and Mo. The Laves phases... be achieved. However, these methods are commonly limited to foams of pure metals like Ni, Cu, and Fe. Complex composition of the foam, also with strong limitations, can be achieved via layer-wise deposition......
at its top. The microstructure of cast Al alloys usually is composed of primary Al dendrites, eutectic silicon, Fe-rich particles and other intermetallic particles are dependent upon alloy composition... components [10]. The fatigue strength of cast Al alloys is profoundly affected by different types of microstructural heterogeneities such as micro- shrinkage/gas defects/pores, gas porosity and eutectic phases......
