Diffusion in bcc Transition Metals

Sharma, B D and Tiwari, G P and Ray, S P (1968) Diffusion in bcc Transition Metals. In: Symposium on Non-ferrous Metals Technology : Papers for presentation, 4th - 7th Dec.1968, National Metallurgical Laboratory (CSIR), Jamshedpur.



Diffusion in metals and alloys is a defect contro-lled process. It occurs as a result of solvent (solute) atom-vacency exchange in the matrix. Diffusion can also occur along short circuiting paths like dislocations or grain boundaries. In all these cases the temperature dep-endence of diffusivity follows an Arrhanious relationship i.e.log D vs l/t plot is linear. The diffusivity is writt-en as D=Do exp(-Q/rt) where D0 and Q are frequency factor and activation energy for diffusion.
