“…The vertical cross-section of the Cu-12Al-xMn ternary phase diagram indicated that the equilibrium phase at room temperature in the alloys with a Mn content above 1 wt% was α+γ+τ. However, the eutectoid reaction β→α+γ was controlled by the cooling rate [38]. In this study, the samples were cooled in the furnace, and the microstructure of the samples indicated that only part of the β phase had undergone eutectoid transformation ( figure 9).…”

Cu-12Al-xMn (x=0, 1, 2, 3, 4%, mass fraction) alloys were produced using powder metallurgy to investigate the effect of Mn content on the alloy's microstructure and mechanical properties. The Cu-12Al (no Mn) and Cu-12Al-1Mn (1 wt% Mn) alloys consisted of the α+γ phases, where the size of the α grains in the Cu-12Al-1Mn alloy are much larger. Mn effectively inhibited the eutectoid transformation at a concentration above 1 wt%. Furthermore, the β phase was converted to the β′martensite phase, which had a monoclinic structure after slow cooling. The phases of the alloy changed from the α+γ phases to the α+β′+γ phases with the further addition of Mn, and the tensile strength of the 3 wt% Mn alloy was 380.59 MPa. The addition of Mn did not have a significant effect on the density of the alloy.

“…However, other studies in dry sliding of some tin and aluminum bronzes in a pin-on-disc test exhibited that tribological behaviour did not relate to mechanical properties like hardness [7]. A very close relation between the microstructure of aluminum bronzes and tribological properties in a dry block-on-ring test was found out [8].…”

-The aim of this study was to investigate the tribological behaviour of laser cladded aluminum bronze tool surfaces for dry metal forming. In a first part of this work a process window for cladding aluminum bronze on steel substrate was investigated to ensure a low dilution. Therefore, the cladding speed, the powder feed rate, the laser power and the distance between the process head and the substrate were varied. The target of the second part was to investigate the influence of different process parameters on the tribological behaviour of the cladded tracks. The laser claddings were carried out on both aluminum bronze and cold work tool steel as substrate materials. Two different particle sizes of the cladding powder material were used. The cladding speed was varied and a post-processing laser remelting treatment was applied. It is shown that the tribological behaviour of the surface in a dry oscillating ball-on-plate test is highly dependent on the substrate material. In the third part a deep drawing tool was additively manufactured by direct laser deposition. Furthermore, the tool was applied to form circular cups with and without lubrication.

“…Because of their high hardness and poor conformability, these alloys are used in applications where good alignment and reliable lubrication are possible. Solid cast aluminum alloy bearings sometimes are used in heavily loaded moderate-speed to high-speed applications [5][6][7][8][9][10]. Therefore, leaded-tin as well as aluminium bronzes form an important category of the bronzes [11].…”
