“…This coherency strain associated with the precipitates contributes to the enhanced mechanical strength in the alloy system. 76,[82][83][84][85][86][87] In summary, the GPA technique has been successfully used to evaluate relative strain mapping at the nanometre scale, providing insight into the mechanical properties of the alloy system. A corresponding high-resolution phase contrast image, the corresponding FFT, and phase maps are shown in Figure 13(a)-(d).…”

“…The DO 19 and L1 2 structures are similar in crystallographic arrangements. [74][75][76] The compelling force of FCC Cu-matrix is crucial for this L1 2 -ordered structure conversion of iron and silicon. This crystallographic compelling phenomenon is the cause for the evolution of novel FCC-based L1 2 -ordered nano-sized precipitates in the copper matrix and is rarely reported in literature.…”

The present paper focuses on developing an optimised strength-conductive alloy in Cu–Fe–Si system. We present the effect of a cost-effective rapid-casting route on modifying the microstructure. The non-equilibrium phase transformation events are tracked and the evolution sequences of metastable phases in the microstructure are elucidated. The metastable phase transformation of the precipitates from DO19- to L12-ordered structure and its role in enhancing thermal conductivity are presented. A density functional theory (DFT)-based calculation also complements the experimental evidence of the relative stability of the evolved metastable phases. One of the key findings is the evolution of L12-ordered precipitates via face centred cubic (FCC)-based interfacial matrix template.
