“…As presented in [ 7 ], solidification rate has a significant impact on a high-tin bronze microstructure. Other research projects presented how tin content changes the mechanical properties of bronzes [ 8 ]. Figure 5 , Figure 6 and Figure 7 show the tensile strength, hardness, and impact strength for various tin contents.…”

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 impact strength of Cu-Sn alloy increases until the tin content is around 5%, more than that will decrease. Tensile strength increases in tin content up to about 10% Sn, yield strength increases to a composition of about 20wt.% Sn [9].…”

“…High tin bronze >17% is used to make various musical instruments. It was used to make church bells in the 11th century [7]- [9], trumpets and percussion instruments and gamelan as the main ingredients [10]- [12]. Tin bronze alloys have castability in a variety of molds, able to be forged, corrosion resistance and good acoustic properties.…”

Composition and pouring temperature are important parameters in the casting. Incorrect composition and pouring temperature settings can cause defects in cast product. Material used in Cu-(20-24)wt.%Sn. The pouring temperature was varied 1000°C and 1100°C. The mold was made using a wax pattern and coated in clay (SiO2). The mold has a length of 400 mm, width of 10 mm and thickness of the cavity varied from 1.5-5 mm. The length of the fluidity tends to decrease with the addition of the composition, while the increase in pouring temperature and the thickness of the mold cavity increases the length of the fluidity. The density increases with increasing composition and temperature of the pour. The high density indicates low porosity. Material hardness and bending decreases to increase composition and pouring temperature. Tensile strength decreases with the addition of composition, while the pouring temperature increases.

“…Advantages of these alloys are, among others, good flowability, strength, ductility, high corrosion resistance and also abrasion resistance at high loads [10][11][12]. In Cu-Sn alloys, Sn content is important since it influences its strength and functional properties [13][14][15][16][17][18]. Due to higher requirements to modern materials, high prices of tin and its short supply, the substitutes of this group of elements are looked for and applied [19][20][21][22].…”

Experimental Investigation and Thermodynamic Modeling of Influence of Nickel and Titanium Content on the Structure and Selected Properties of Tin Bronzes

et al. 2021

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.
