“…The standard strengthening techniques are precipitation, dispersion of second phases, post-working, rolling, etc. 6–42 All these standard metallurgical techniques impart severe consequences in damaging transport properties due to the insertion of defects-scattering centres. This retrogression in the conductive properties is a design challenge for copper-based alloys.…”

“…This sustained engineering design-oriented challenge can be addressed through the wisdom of microstructural manipulation during the processing of the alloy system. 1–42 Insertion of intermetallic dispersoids may be one of them and it is produced through powder metallurgical route. This production route is costly in terms of processing complexity.…”

“…However, these developments suffer from limited conductivity at elevated temperatures due to the growth of twins. [5][6][7][8][9][10][11][12] Precipitation hardening in copper alloy systems is also a standard metallurgical route. However, due to the coarsening nature and presence of precipitates as a scattering centre, such attempts at high service temperature are not advantageous.…”

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.
