	abstract = {PLASMA DISRUPTION PHENOMENON OBSERVED IN ALL TOKAMAK FUSION REACTORS IS A       MAJOR MATERIALS RELATED ISSUE.  ITS EFFECTS ON THE FIRST WALL COMPONENTS HAVE   TO BE CONSIDERED FOR DESIGN PURPOSE.  IN FACT THESE COMPONENTS ARE SUBJECTED,   IN CASE OF A DISRUPTION, TO EXTREMELY HIGH HEAT FLUXES (ABOVE 108 W/M2) ON      VERY SHORT TIME SCALES (1MS).  THE HIGH HEAT FLUX CAUSES VAPORIZATION AND THE   PRODUCTION OF A MOLTEN LAYER.  THE RESULTING DAMAGE CAN BE EVALUATED BY DETER-  MINING THE PROPERTIES OF THE RESOLIDIFIED AND HEAT AFFECTED MATERIAL.  IN THIS  STUDY THE MORPHOLOGY, THE MICROSTRUCTURE AND THE MECHANICAL BEHAVIOUR OF SOME   RESOLIDIFIED AND HEAT AFFECTED (CR-NI AND CR-MN) AUSTENITIC STAINLESS STEELS,   OF INTEREST FOR NUCLEAR FUSION PURPOSE, WERE INVESTIGATED AFTER PLASMA DISRUP-  TIONS, SIMULATED BY AN ELECTRON BEAM FACILITY (POWER DENSITY 8 KW/CM2, PULSE    LENGTH 5-20 MS).  CELLULAR CELLULAR-DENDRITIC AND DENDRITIC GROWTH MODES OCCUR- RING DURING RESOLIDIFICATION PROCESSES, SEGREGATION AND SOLIDIFICATION CRACKS   WERE ANALYSED BY OPTICAL AND SCANNING ELECTRON MICROSCOPY AND MICROCHEMICAL     MEASUREMENTS.  THE DEGRADATION OF MECHANICAL PROPERTIES WAS EVALUATED BY HARD-  NES MEASUREMENTS AND UNIAXIAL TENSILE TESTS ON SPECIMENS TAKEN FROM ZONE AFFEC- TED BY SIMULATED DISRUPTIONS.  SOME FRACTURE MECHANICS PROCEDURES HAVE BEEN     APPLIED IN ORDER TO EVALUATE THE IMPORTANCE OF THE RESOLIDIFICATION CRACKS
