Effect of Two-Cycle Heat Treatment on Mechanical Properties of Ductile Iron

Abstract:

The aim of this study is to investigate the mechanical properties of ductile iron after treatment with two-cycle heat treatment processes which modified from austempering. The modified heat treatments have two stages holding temperature. Ductile iron was austenitized at 900 °C for an hour and followed by transferring the sample to other furnace which was set at different temperatures of i) 250 °C; ii) 300 °C; iii) 350 °C without quenching for 1.5 hours. Tensile (ASTM E8M), impact (ASTM-E23-1990) and Rockwell hardness tests were carried out to study the mechanical properties of the ductile iron. It was found that the sample which was heat treated using two-cycle heat treatment process at temperature of 250 °C contributed to better absorbing impact energy properties and hardness properties. Meanwhile, sample that heat treated at 350 °C has higher tensile strength.
