Description

The influence of preliminary cold deformation in the range of 5-70% on strength and plasticity of 12Kh18N10T steel irradiated by 50 MeV helium ion beam was studied. High-temperature tests were conducted at 1073K with 0.13 mmxmin-1 tension rate. It is shown that irradiation leads to sharp decrease of high-temperature ductility. Prior deformation may produce a positive effect only in the case of martensite α'-phase formation in deformation range of 20-42%. Different effect of methods of irradiation on embrittlement is noted. High-temperature embrittlement is observed for all degrees of prior deformation during volume alloying by helium ions
