Microstructures and Mechanical Properties of Troostite Nodular Cast Iron by Heat Treatment

Abstract:

Article Preview

A troostite nodular cast iron was obtained by a heat treatment process of controlled cooling, reheating-up and isothermal treatment. Experimental results show that the troostite substrate demonstrates an interlamellar spacing below 100 nm. The supercooling condition in this specific heat treatment process is key to the formation of troostite. The mechanical properties are excellent, with tensile strength of 905.5~1029.5 MPa, hardness of 30.8~32.8 HRC, and elongation of 3.1~4.0 %.
