Lightweight MBT Track Pin Development

Abstract

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 20(registered) liner installed by interferences (shrink) fit into an outer steel casing. DWA1 20(registered) is a metal matrix composite incorporating aluminum powder and ceramic particulate reinforcement. The DWA1 20(registered) system selected for the track pin application is 25 volume percent silicon carbide particulate reinforced 6061 aluminum (25v/o SiCp/6061); however, other Combinations are feasible. Commencing with DAW1 20(registered) 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.
