PLASTIC DEFORMATION AND MARTENSITIC TRANSFORMATION IN IRON ALLOYS.
Abstract
An electron transmission study has been made of the martensite transformation in a series of stainless steels. The influence of chemical composition on martensite morphology has been investigated and the composition ranges which transform to lath, surface and plate martensite determined. Using polycrystalline samples of two compositions which transform to lath martensite, an investigation was conducted into the influence of prior plastic deformation on martensite formation. This is of course a contribution to the fundamental understanding of the ausforming process. A further investigation in this area was an examination of the transformation which occurs during plastic deformation at temperatures approaching the M sub s. These experiments were performed on single crystals of the composition Fe-17Cr-16Ni. Finally, transmission studies were carried out to determine the processes occuring during reversion of an Fe-16Cr-12Ni alloy heated in the temperature range 500 to 900 C. (Author)
