Metallographic Polishing and Grinding Grinding of Specimens The surface of the specimen is first made flat by an abrasive belt or rotary disc machine These machines are frequently equipped with coolant attachments to ensure cool cutting and to help wash abraded particles from the belt or disc Care should be taken to prevent overheating of
Developed in 1948 nodular or ductile cast iron has its graphite in the form of very tiny nodules with the graphite in the form of concentric layers forming the nodules As a result the properties of ductile cast iron are that of a spongy steel without the stress concentration effects that flakes of graphite would produce Tiny amounts of
When the grinding speed was increased to v s = 32 m s both CG and UAG produced larger smooth areas and more plastic grooves originating from ductile removal mode; additionally a less brittle fracture was found It was evident that the difference between ground surface micro morphology caused by observed processing methods decreases with
