Critical Review Titanium Matrix Composites
Titanium matrix composite systems are reviewed with emphasis on two systems; those containing silicon carbide coated boron filaments (B/SiC-Ti) and those containing beryllium metal either in powder or continuous filament form (Be/Ti).
Both of these composite systems have properties generally su?perior to aluminum matrix composites, with certain noted exceptions in the 0° direction (tensile strength and fatigue). Notable are the good transverse properties of titanium matrix composites; Be/Ti flat filament composites appear outstanding in this respect. Be/Ti composites have the disadvantages associated with machining and handling beryllium, a hazardous material. This is offset by the potential ease with which standard metallurgical processing tech?niques may be applied to both co-extruded powder and filamentary types of these composites.
