摘要：

During melt texturing, secondary phases such as 2-1-1 particles and Ba-Cu-rich platelets are generated. We describe a new method based on rapid heating for controlling the final 2-1-1 particle size and the nature of the Ba-Cu-rich platelets. Using this new technique, 1-2-3 with a very finely dispersed 2-1-1 phase has been produced. Optical and electron microscopy have been used to characterise the final microstructure.
