抄録

The effect of applied stress upon the martensite transformation curve has been investigated in a steel containing 1%C and 5%Ni. When stresses are applied during transformation, a tensile stress raises Ms temperature as is well known, but it opposes the transformation as a whole; on the contrary, a compressive stress promotes the transformation without remarkable effect on Ms. The similar directional stress effect is observed when stresses are applied at the temperature range entirely above Ms. These results seems to indicate that the coherent embryo of martensite is formed due to Bain’s deformation for transformation, preferentialy in regions of the lattice subjected to uniaxial compressive stress, as in the neighbourhood of dislocation.
