Grain boundaries
Grain boundaries
(OP)
Hello all,
After grinding a 12" 25/20 centrifugal casting to a 10 Ra, the surface appearance of this tube looks uneven in color(light and dark areas). It has been explained to me that this is a reflection of the grain boundaries? Is this true because of the steel mixture being less homogeneous.
Thank you in advance for your answers.
Doug
