AbstractFerritic spheroidal-graphite cast irons of four different silicon contents from 2.0 wt% to 3.4 wt% were deformed in tension at various strain rates and test temperatures. The results indicate certain types of flow instability at certain temperature ranges of dynamic strain ageing. By judging from the characteristics of the flow patterns and apparent activation energies, it is suggested that interstitial carbon plays the major role in low temperature flow instability, whereas the high temperature flow instability is mainly affected by substitutional silicon. The above suggestion on the role of substitutional silicon is also supported by static strain ageing tests.As indicated by the data obtained at the onset temperature of flow instability, the activation energy for carbon diffusion increases with increasing silicon content. Rationalisation based on a nearest-neighbour pair bonding model shows that the addition of substitutional silicon raises the activation energy for carbon diffusion by raising ...

AbstractExperimental data on a range of pure C-Fe and C-Cr-Fe alloys have been utilised to determine the locations of solidification range isotherms and liquidus sub-field boundaries on the Ferich corner of the metastable C-Cr-Fe liquidus surface. The liquidus surface gives information on the primary phase formed during solidification, and the sub-fields provide additional information, mapping the entire solidification sequence as a function of alloy composition. The solidification sequences followed by typical alloys from each of the ten sub-fields identified have been described with reference to their respective microstructures.
