Development of microstructure in advanced solidification processing

This paper gives an overview of the use of process monitoring measurements, computer modelling calculations and electron microscope material characterization techniques to understand and control the manufacture of materials by a variety of advanced solidification processing methods. Examples which are discussed include: (1) spray formed Al alloys and composites for aerospace structures; (2) squeeze cast Al alloys and composites for automotive components; (3) melt spun Al bearing alloys and; (4) melt spun amorphous Fe alloys for distribution transformer cores and structural components; and (5) plasma sprayed Ti composites for aeroengine compressors.
