2) High toughness ductile iron 高韧性球墨铸铁 1. The production process of as-cast high toughness ductile iron was reviewed,and the effects of chemical composition,desulphurization process,nodulizing and inoculation process on the production of as-cast high toughness ductile iron was analyzed. ...
Pure iron is not used nearly as often as steel. Steel has better strength, hardness, toughness, and corrosion resistance than iron. The ductility of steel depends on its chemical composition. In general, steel’s ductility ranges from 4 to 40%. Steel has been one of the most important ...

Table 1. Chemical composition of as-received cast iron (wt.%). CSiMnPS 3.5 2.5 0.2 <0.0015 <0.0015 Samples were randomly chosen from the two sample groups and were austenitized at 890 °C for 20 min, then quenched rapidly to 180 °C by controlling the patented liquid (10 wt.% sodium...
Such microstructure and the mechanical properties of the iron are significantly affected by the conditions of the austempering treatment and the chemical composition. In this study, several grades of ductile iron were austempered under various conditions. The relationship between the impact strength, the...
Experimental ductile irons with the composition range given in Table 1 were produced in a Morgan gas-fired furnace (with 25 kg capacity lift-out crucible) and a high-frequency melting plant of 20 kg capacity (with a tilting crucible). After melting, the iron was superheated at 1550 °C and...
