Thanks astronuc for the reply.Is it possible to visible prior austenite grain boundary in a ferrite+pearlite microstructure?I read somewhere that during austenite decomposition, further nucleation is happening in austenite grain boundary.
PS:Prior austenite grain boundary term is used in martensite microstructure.
