Improvement in hardness, wear rate and corrosion resistance of silicon bronze using gas tungsten arc

The Effect of Heat Input, Annealing, and Deformation Treatment on Structure and Mechanical Properties of Electron Beam Additive Manufactured (EBAM) Silicon Bronze

“…This work is part of research focused on finding methods for improving microstructural and mechanical characteristics of additively manufactured metals and alloys. Cu-3wt.%S-0.8wt.%Mn bronze is a single phase FCC alloy with low stacking fault energy, the plastic deformation of which occurs by dislocation gliding and twinning [8]. It is structurally similar to the earlier reported additively manufactured Cu-7.5wt.%Al bronze [23], and therefore one of the objectives was to compare between types of microstructures obtained at different heat input levels.…”

“…It is known [8] that plastic deformation mechanisms in silicon bronze occur by dislocation movement and twinning. The behavior of samples and contributions of different mechanisms of plastic deformation can be analyzed using a dependence of strengthening rate dσ dε on the strain (Figure 20).…”

“…Another approach is feasible that allows modifying only subsurface layer structures by irradiation the targets with concentrated energy sources, such as electron beam, laser, and arc discharge. For instance, arc surfacing was used to improve hardness and wear resistance of silicon copper alloy by grain refining [8]. Laser surfacing on C63200 bronze resulted in reducing ductility and increasing the yield strength, while keeping the ultimate strength constant [9].…”

Atmospheric corrosion of Cu-Si-Mn bronze for contemporary art under simulated runoff and continuous immersion conditions

“…However, very few studies are present in literature investigating the corrosion behaviour of Si-bronzes, containing significant amounts of Zn (>2 wt%) and lower amounts of Mn (<0.2 wt%) than Cu-3Si-1Mn bronze [17][18][19]. Moreover, these studies are carried out only under full immersion in soft, hard, drinking water or 3.5 wt% NaCl solution, focusing on technological/industrial applications.…”
