AbstractWe have investigated excimer laser irradiation of 2000-Å-thin as-deposited Al films on SiO2. Microstructural analysis of the irradiated films conducted with AFM and EBSD techniques reveals that there exists a wide energy density interval over which large equaxed grains with a strong (111) texture are obtained. Based on thermal, transformational, and microstructural considerations, we propose a heterogeneous nucleation model to account for the observed behaviors, and discuss the implication of the model on the phenomenon of heterogeneous nucleation of crystalline solids in condensed systems as regards the thermodynamic role played by the orientation of subcritical clusters.

AbstractAn amorphous-nanocrystal reinforced composite coating was fabricated on a TA15 alloy by laser cladding of BN-NiCoCrAlY mixed powders. Experimental results indicated that a portion of the amorphous phases just began to crystallize when the laser molten pool had completed the solidification process. The nucleation and growth of the amorphous phases were retarded by the nanocrystalline phases to a certain extent during the crystallization process. Due to the rapid solidification process of the laser molten pool, a number of the fine precipitates were produced. The production of eutectics, such as Co-Ti and Ti-Si compounds, in such a coating greatly promoted the formation of amorphous phases.
