Abstract

Although double-shear theories of martensite crystallography vere considered more suc- cessful than the classical theories, stili it is not possibîe to explain the complete nature of the trans- formations especially in Fe alloys with ^225}f and {259}^ habit planes. Since the double-shear theories give better results than the classical theories and more than two simple shear elements were observed by electron microscope observations in these transformations, it is concluded that the number of the simple shears used in these theories should be increased. The triple-shear model which was based on the above mentioned results was found to be in good agreement with the ob­ servations in some Fe alloys with ^225jf habits. The same model was also applied to the Fe-Ni-C alloys with {259jf habits and gave succesful results.
