Abstract
Polycrystalline transparent Magnesium Aluminate Spinel (MAS) is an
attractive material for a wide range of optical, electronic, structural
and armor applications. Transparent MAS samples of 20-30 mm diameter and
3-5 mm thickness has been successfully fabricated by means of Field
Assisted Sintering Technology. The dynamic response of MAS was
investigated by plate impact experiments. The values of the Hugoniot
Elastic Limit (HEL) and the spall strength were derived from the VISAR
records of the velocities of the free sample surface or of the
sample/window (PMMA) interface. The dependence of the HEL and the spall
strength on the impact stress, as well as, correlation between the spall
strength and the width of the loading pulse are discussed.
