“…The precipitates in various Cu alloys generally show different phase structures, in which the coherent precipitation of metastable ordered L1 2 in the FCC-Cu solid solution matrix can appear in the commonly-used Cu-Ni-Sn alloy system [ 75 , 76 , 77 ]. The model alloy is the Cu-15Ni-8Sn (wt.%, C72900), in which the (Cu,Ni) 3 Sn precipitates have four crystal structures, FCC-DO 3 , tetragonal DO 22 , ordered L1 2 , and orthorhombic δ.…”

High-performance conventional engineering materials (including Al alloys, Mg alloys, Cu alloys, stainless steels, Ni superalloys, etc.) and newly-developed high entropy alloys are all compositionally-complex alloys (CCAs). In these CCA systems, the second-phase particles are generally precipitated in their solid-solution matrix, in which the precipitates are diverse and can result in different strengthening effects. The present work aims at generalizing the precipitation behavior and precipitation strengthening in CCAs comprehensively. First of all, the morphology evolution of second-phase particles and precipitation strengthening mechanisms are introduced. Then, the precipitation behaviors in diverse CCA systems are illustrated, especially the coherent precipitation. The relationship between the particle morphology and strengthening effectiveness is discussed. It is addressed that the challenge in the future is to design the stable coherent microstructure in different solid-solution matrices, which will be the most effective approach for the enhancement of alloy strength.

“…Microstructure, wear behaviour, mechanical properties and hardness of Cu-Sn-Ni spinodal alloys in wrought condition have been reported extensively. Cribb and Ratka [1], Sadi and Servant [2] and Caris et al [3] found that wrought alloys possess higher yield strength. Ilangovan and Sellamuthu [4] in their investigation reported that Ni contributes to spinodal or ordering process which increase the peak hardness of sand cast Cu-Ni-Sn spinodal alloys.…”

An investigation was conducted to find the optimum aging temperature and aging time for Cu-Sn-Ni spinodal bronze alloys with varying nickel wt% cast in metal mould. The specimens were subjected to solutionisation and were aged at 250°C, 300°C, 350°C, 400°C and 450°C to induce spinodal decomposition. The microstructural observation reveals that the dendritic structure of the as-cast alloy was completely eliminated after solutionisation and grain boundary precipitates were formed with increase in aging time. The peak hardness and the peak aging time increases with increase in nickel content. This implies that nickel contributes to spinodal decomposition process.

“…Concerning the mechanical properties, to the best of the authors' knowledge, few papers have dealt with the strength and fatigue behavior of Cu-15Ni-8Sn, and none deals with the mechanical behavior of Cu-15Ni-8Sn cast alloy. Indeed, only the alloy obtained by powder metallurgy was investigated in [11,12], where the influence of the aging treatment was assessed in terms of the yield stress, ultimate stress and fatigue endurance of thin sheets. In particular, concerning the fatigue analysis, strain controlled tests were performed and the results focused on the alloy behavior in the range of low cycle fatigue, highlighting some differences between genuine and heat treated specimens in terms of fatigue life only at very low cycles.…”

In this paper, the static and fatigue properties of a Cu-Ni-Sn alloy are investigated. Tensile tests, hardness tests and microstructural analyses using optical and scanning electron microscopy (SEM) were performed and two sets of fatigue tests, with load ratio (R) R = − 1 and R = 0 , respectively, were carried out. The results showed the capability of the alloy to bear high static stress, thanks to its good strength properties. However, the fatigue tests showed a strong sensitivity of the alloy fatigue properties depending on the raw material batch. The comparison between microstructural analyses and fatigue test results showed a strong correlation; in particular, the specimens having a more inhomogeneous microstructure showed lower durability. In addition, the different microstructure also affected the fracture surface morphology as highlighted by SEM analyses.
