“…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.

“…Some filler alloys, including Ag-Cu, Ag-Cu-Ti, Ag-Cu-In (or Sn)-Ti (or Zr), Cu-Sn-Ti, etc. have been successfully tested and used by various investigators experimentally to join the different metal/ceramic or ceramic/ceramic systems [2][3][4][5][6][7][8]. Active elements such as Ti, Zr, Cr, etc., can react with ceramic particles leading to a strong chemical bonding between the joint components at the joint interface.…”

“…Active elements such as Ti, Zr, Cr, etc., can react with ceramic particles leading to a strong chemical bonding between the joint components at the joint interface. Rajendran et al [3] joined the Cu to Al 2 O 3 using the active alloy Ag-18Cu-6Sn-3Zr-1T and found out that the contact angle can be reduced with the addition of Ti and Sn to Ag-Cu-Zr alloys. Silver-base active filler alloys have been widely studied by various researchers [6][7][8][9].…”

In dissimilar brazing, the differences in physical properties between the components lead to residual stresses. An active filler alloy Cu-20.5Sn-20Ag-3.5Ti was developed to braze the Cu-Al 2 O 3 composites (containing 25 and 50 volume pct. Al 2 O 3 ) to copper. Two mechanisms were proposed for chemical bonding as a result of alumina reinforcements reduction by the active titanium, including the formation of Ti 3 (Cu,Al,Sn) 3 O layer beside the Ti 2 O in Cu/Cu-25%Al 2 O 3 joints; and the solidification of Ti 3 (Cu,Al,Sn) 3 O in the vicinity of TiO layer/Cu 4 Ti islands in the Cu/Cu-50%Al 2 O 3 joints. Some intermetallic compounds such as Cu 3 Ti 2 and Cu 41 Sn 11 are formed/coarsened with an extra increase in brazing temperature. An increase in brazing time improves the thickness of the TiO x layer with no sensible effect on Ti 3 (Cu,Al,Sn) 3 O width.
