Composites of tungsten wire reinforced stainless steel were prepared by a specially developed fabrication method based on hot isostatic pressing. This composite system was chosen as a convenient model material. Its mechanical properties were investigated to provide a basis for the evaluation of the potential advantages and possible difficulties to be expected in the application of such material to turbine blades. Results obtained so far suggest that composites based on W-alloy wires show considerable promise as blade materials for very high service temperatures. Further research effort is required, particularly on fiber/matrix interaction, thermal fatigue and to optimize the properties of the reinforcement wire.
