This paper reports the effect of neutron irradiation on strength of high manganese steel which is a candidate for nuclear fusion reactor components. Cryogenic temperature strengths of two kinds of high manganese steel, A-T (18Mn-6.8Cr-4.7Si) and B-T (22Mn-6.4Cr-4.4Si-0.18N), and their electron beam welded joints were investigated under various irradiated conditions. Results obtained are summarized as follows. (1) At cryogenic temperature, high manganese steel A-T exhibited a faint serration,
more » ... showed a clear serration. (2) Ultimate tensile strength and 0.2% proof stress of base metal and electron beam welded joint of A-T and B-T increased with increasing of neutron fluence.
