Luders band arises in low carbon steels and these bands then requires less stress for their propagation than for their formation because of the freeing of dislocations from their solute atmospheres.

Dear Aditya
Thanks in advance for your important question, Luders bands appear not in all super alloys, this highly depends on base element of such kinds of alloys, please go to the famous book of Ashby, attached below.

I think it forms only in Fe-base superalloy. Because Solubility of C in Fe is defined by allotromophic forms of it. The solubility of C in Ni base and Co is low. I not sure whether it would form in such superalloy
