X-RAY INVESTIGATION OF THE MARTENSITIC TRANSFORMATION IN PURE COBALT, Co-Cu AND Co-C ALLOYS

摘要

Stacking disorder in martensite of pure Co, Co-(9-10)wt.%Cu and Co-(0,25-0.632)wt.%C alloys has been studied by X-ray diffraction. Fluctuations of alloying element concentration in different grains of polycrystalline material are supposed to be the most probable reason for the variety of long-period poly types of Co alloys.
