“…Furthermore, the addition of iron in Cu-Sn alloys changes the properties of the alloy. Hence, a study based on the above-mentioned topic was put forward by Klempka et al [ 63 ]. Both alloying elements, aluminium and iron caused grain refinement in Cu-Sn10 alloys.…”

The article reviews the progress made on bronze alloys processed through various casting techniques, and focuses on enhancements in the microstructural characteristics, hardness, tensile properties, and tribological behaviour of Cu-Sn and Cu-Sn-Ti alloys. Copper and its alloys have found several applications in the fields of automobiles, marine and machine tools specifically for propellers in submarines, bearings, and bushings. It has also been reported that bronze alloys are especially used as an anti-wear and friction-reducing material to make high performance bearings for roller cone cock bits and warships for defence purposes. In these applications, properties like tensile strength, yield strength, fatigue strength, elongation, hardness, impact strength, wear resistance, and corrosion resistance are very important; however, these bronze alloys possess only moderate hardness, which results in low wear resistance, thereby limiting the application of these alloys in the automobile industry. The major factor that influences the properties of bronze alloys is the microstructure. Morphological changes in these bronze alloys are achieved through different manufacturing techniques, such as casting, heat treatment, and alloy addition, which enhance the mechanical, tribological, and corrosion characteristics. Alloying of Ti to cast Cu-Sn is very effective in changing the microstructure of bronze alloys. Reinforcing the bronze matrix with several ceramic particles and surface modifications also improves the properties of bronze alloys. The present article reviews the techniques involved in changing the microstructure and enhancing the mechanical and tribological behaviours of cast Cu-Sn and Cu-Sn-Ti alloys. Moreover, this article also reviews the industrial applications and future scope of these cast alloys in the automobile and marine industries.

The effects of different Fe-Ti ratios on the microstructure, mechanical properties and softening resistance of Cu-Fe-Mg-Ti alloy were studied in detail by controlling the atomic ratios of Fe and Ti elements (1:1, 1:2, 2:1) at a certain content of Fe and Ti elements, using hardness and electrical conductivity tests and OM, SEM, TEM and XRD observations. The results showed that after 70% cold rolling and aging at 550 ℃, the FT12 alloy had a peak aging hardness of 189.5 HV and an electrical conductivity of 44.2% IACS, the FT11 alloy had a peak aging hardness of 173.9 HV and an electrical conductivity of 51.3% IACS, and the FT21 alloy had a peak aging hardness of 166.5 HV and an electrical conductivity of 64.1% IACS. TEM analysis showed that all three groups of alloys formed the precipitation phase Fe2Ti phase, which improved the strength of the alloys.

“…The authors have already carried out research concerning various alloy additions influencing the properties of bronzes [23,[30][31][32][33]. Regardless of the fact that several multicomponent bronzes based on the Cu-Sn composition were developed and described in the scientific literature, looking for new alloys and an in-depth analysing of the results is fully justified [34][35][36].…”

Investigations are conducted in order to maintain or to improve the selected properties of the group of foundry copper-tin alloys with nickel and titanium additions, at a limited fraction of the critical (deficit) element such as tin. The crystallisation process, as well as changes of the microstructure and selected mechanical properties of the CuSn8 alloy—occurring due to introducing alloying additions—were analysed. Investigations of the macro and microstructure were performed using optical and scanning electron microscopy. Based on the thermal analysis and thermodynamic modelling using the CALPHAD (CALculations of PHAse Diagrams) method, the crystallisation process was analysed. The identification of phases was performed by XRD (X-ray diffraction). In addition, such parameters as tensile strength-UTS, elongation-A and hardness-HBS were tested. Under the influence of the introduced titanium, the columnar crystals are reduced due to the crystallisation of the alloy at the walls of the mould. Precipitations (intermetallic phases) crystallize first (primary). The intermetallic phases associated with the presence of the alloying elements nickel and titanium are located in the interdendritic regions. In tin bronzes with titanium additions, hardness (HBS) increases, tensile strength (UTS) negligibly decreases, while elongation (A) significantly decreases. In the case of CuSnNi bronze, the addition of 0.2 wt.% Ti increases the hardness and increases ultimate tensile strength (UTS), while reducing the elongation (A). Higher Ti additions increase HBS, slightly decrease the tensile strength, and significantly reduce the elongation.
