Rotary rolling of quenched-and-tempered hypereutectic silumins 01392 and AK18 makes it possible to refine the primary and secondary crystals of silicon and change them from plate to globule form. Adding to similar results obtained previously on hypereutectic silumins 01390 and 01391 that were not quenched and tempered, rotary rolling of quenched-and-tempered hypereutectic silumin AK18 also refines and changes the shape of the excess phase Al9FeNi that is usually present in piston-grade silumins and determines their resistance to heat.
