“…The stress and strains induced to a crystal structure due to the difference between the radius of the solvent and solute atoms is one of the reasons for the formation of shift in the XRD peaks [25,26]. The lattice parameters obtained in this research are in good agreement with those obtained in a previous work [22].…”

This study was aimed at developing lead-free brass alloys with the goal of substituting lead element with tin. For this purpose, lead-free alloys with tin were developed and the microstructure, hardness and machining behaviour of the Cu–30%Zn alloy was compared with Cu–30%Zn– x%Sn ( x = 1.2, 3.2, 5.4, 8, 11.4, 13.9, 17.4). The results showed that the addition of Sn to single-α phase brass led to the formation of duplex (α + β′) brass and then the formation of (β ′ + Ɣ ) brass both with increased hardness. In addition, the addition of Sn to Cu–30%Zn alloy led to the decrement of equivalent machining forces ( Fm), surface roughness and also the promotion of chip fragmentation due to the formation of the β ′ phase, which is an improvement in machinability.

“…Figure 5(b), which shows the XRD spectra obtained from the samples containing 11.4-17.4 wt-% Sn, illustrates that the microstructure of these alloys consisted of both β´and γ-phases. The compositions of α-, β´and γ-phases are determined to be Cu 0.64 Zn 0.36 [21], CuZn [22] and Cu 5 Zn 8 [23], respectively.…”
