The freckling mechanism of superalloys

Freckles are macro-segregation defects which are usually found in nickel-base superalloys or specialty steels and which occur during solidification. They are presently one of the major defects encountered in advanced casting technology of superalloys. Two modified Rayleigh criteria have been sugg...
