Dynamic response of TiC-steel, ceramic-metal composite. Conference Paper uri icon

abstract

  • Abstract The dynamic response of a TiC-carbon steel, ceramic-metal composite, was studied in planar impact experiments using a copper impactor with velocity in the 100 to 500 m/sec range. The composites were prepared by pressureless infiltration of ceramic preforms with molten steel. The metallic component had either a pearlitic or a martensitic microstructure, as determined by appropriate heat treatments. A fully dense TiC sample and a 1060 steel specimen in the pearlitic and martensitic states were used as reference samples. The values of HEL and spall strength were obtained from the VISAR records of free surface velocity of the impacted samples. Quenching the standard steel and the composite increased the HEL and the spall strength. The increased tensile strength can be attributed to the presence of the increased strength of the metallic component that prevents the development of cracks …
