Microstructural analysis reveals that the as-received bulk sample displayed a graphitic structure while the rapidly cooled samples display decreasing amounts of -Fe as the cooling rate increases. At moderate cooling rates is replaced with and Fe 3 C, while at higher cooling rates with . Microhardness increase with cooling rate but cannot be mapped uniquely onto cooling rate, suggesting undercooling also influences the mechanical properties. Effect of rapid solidification on

Dynamics of core–shell particle formation in drop-tube processed metastable monotectic alloys

“…Determination of particle cooling rate utilises the model developed in [22] for the balance of heat fluxes, assuming that particles rapidly attain terminal velocity. Full details of the model are given in [22], with the parameters appropriate to the processing of Co-Cu melts in nitrogen being given in [16]. The resulting estimated cooling rate, as a function of droplet size, is shown in Figure 2, where the error bars show the level of uncertainty resulting from grouping particles in standard sieve sizes, i.e.…”

Phase Transformation, Microstructural Evolution and Property Modification in Rapidly Solidified Grey Cast Iron

“…It is a typical low alloyed commercial grey cast iron with elemental composition as compared to ASM standard shown in Table 1 [5]. It was confirmed using XRF analysis to be hypoeutectic with carbon equivalent, C eq .…”

Cast Iron Cooling Rate Variation Using Cooling Channels: A Numerical Approach

“…The effect of the cooling fluid flow rate on the cooling curve of the cast iron is minimal. An increase in the flow rate by a multiple of five (5) resulted in a slight change in the cooling curve.…”

“…The huge demand for cast iron in the automobile, machinery, and construction industries has placed a premium on its production. The grain size of cast iron is an influencer of its mechanical properties [1][2][3][4][5][6]. The grain size is dependent on the cooling rate [7].…”
