Abstract
The spallation behavior of Bsub4C, SiC and TiBsub2 was investigated with respect to loading stress and impactor material. The experiments were performed at a planar impact facility equipped with a VISAR velocity interferometer. The spall stress was determined from the spall signal in the velocity- time profile. The fragments of TiBsub2 were softly recovered. From the remaining target thicknesses the width of the spall zone could be determined.
