摘要：

Resistivity measurements were used to determine the characteristic properties of the martensitic transformation in β1‐brass (39.4 wt% Zn) before and after neutron irradiation. The doses (Φ t) varied between 5 × 1016 and 5 × 1018 neutrons/cm2 (E > 1 MeV). Neutron irradiation decreased the martensitic‐start temperature (Ms) up to 8 °C and increased the maximum rate of trasformation. Ms was further decreased when β1‐brass was annealed at 150 °C after irradiation. A small decrease in Ms was observed when unirradiated, quenched β1‐brass was annealed at 150 °C. Possible mechanisms which give rise to the inhibition of the martensitic transformation, such as dislocation pinning, are discussed. Copyright © 1968 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim
