An 18 month program was conducted by DWA Composite Specialties, Inc., for the U.S. Army Tank-Automotive Command Research and Development Center, Warren, for Light Weight MBT Main Battle Tank Track Pin Development. The track pin is composed of a DWA1 20registered liner installed by interferences shrink fit into an outer steel casing. DWA1 20registered is a metal matrix composite incorporating aluminum powder and ceramic particulate reinforcement. The DWA1 20registered system selected for the track pin application is 25 volume percent silicon carbide particulate reinforced 6061 aluminum 25vo SiCp6061 however, other Combinations are feasible. Commencing with DAW1 20registered billets, tubes were extruded, then cut to size and machined for shrink-fit assembly into the pre-sized H-13 steel tube casings. The steel was heat-treated prior to insertion. The hybrid pin was subsequently subjected to DWA1 20 deg heat-treat parameters, followed by end-configuration machining.
