Özet:

 

The radiation damage effects produced by 800 MeV proton  irradiation on the tensile properties of the two iron base alloys,  Fe-2.25Cr-1Mo and Fe-12Cr-1Mo (HT-9) were determined.  It was observed  that work hardening rate and uniform strain decreased upon  irradiation.  The values of Young's modulus were much lower for the  irradiated samples than the unirradiated samples.  It is thought that  this is not due to proton irradiation but mainly due to the  difficulties encountered in the tensile test measurements.  Proton  irradiation caused an increase in the yield strength and ultimate  tensile strength and a slight decrease in ductility.  Although the  rate of work hardening decreased upon irradiation, both iron base  alloys showed some degree of work hardening even under high proton  fluence.  These results indicate that, both alloys can be used as  window materials in proton accelerators and as the first wall and  structure-blanket materials in nuclear reactors.
