“…Cu-Sn-Ti based brazing alloys are widely used for joining materials, such as diamond/steel matrix tools [ 77 , 78 , 79 , 80 , 81 , 82 , 83 ], metal–ceramics [ 84 ], and CBN abrasive tools [ 85 , 86 , 87 ]. The most common alloys previously used for brazing were alloys based on Ag-Cu-Ti.…”

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.

“…Cu-Sn-Ti alloy powders with the chemical contents Cu 72 wt%, Sn 18 wt%, and Ti 10 wt% were chosen as the filler alloy, which has favorable wetting ability on graphite and alumina ceramic material during brazing [12,13]. The solidus and liquidus temperature of Cu-Sn-Ti alloy was 790 ∘ C and 810 ∘ C, respectively.…”

“…In the interface II, Ti, Sn, and Cu atoms are redistributed in the joint. Hsieh and Lin carried out a study indicating that the addition of Ti enhanced the wetting behavior of the molten filler alloy, but its optimal concentration was affected by the concentration of Sn [13]. The concentration of Sn and Ti promoted the formation of Sn-Ti intermetallic compounds in the filler layer.…”

In order to fabricate the abrasive wheels with good grain self-sharpening capacity, two types of multicrystalline CBN grains, that is, polycrystalline CBN (PCBN) and binderless CBN (BCBN), were brazed using Cu-Sn-Ti alloy, respectively. Comparative investigation on the brazing interface, compressive strength, and wear properties of the different grains was carried out. Results obtained show that the PCBN grains have more intricate reaction, more complicated resultants, and thicker reaction layer than the BCBN counterparts under the identical brazing conditions. Though the average compressive strength of the PCBN grains is similar to that of BCBN ones, stronger self-sharpening action by virtue of the microfracture behavior takes place with BCBN grains during grinding. As a consequence, compared to the brazed PCBN wheels and the conventional monocrystalline CBN (MCBN) ones, longer service life is obtained for the brazed BCBN wheels.
