“…[1] Thus, even if the general microstructure of SLM and forged samples is not the same, the corrosion behavior seems to be mainly dependent on the morphology and the type of constituent phase which give a similar effect on the corrosion resistance. It can be concluded that the corrosion performance of SLM in the specific heat-treated condition is comparable to that of forged samples, as observed also by Hammasian Ettefagh et al [42] .…”

“…For AM, a limited choice of alloys is used due to prototyping with specific properties [4]. The most widely used alloy for AM is Ti-6Al-4V [1,[5][6][7][8][9][10][11][12], especially concerning fatigue properties [13][14][15], due to wide use in medical, aircraft, aerospace and automotive industries belonging to high-value complex parts requiring only limited production volumes.…”

“…This is the formation mechanism of the SLM-produced Ti6Al4V3Cu alloys’ microstructure, shown in Figure 3 , while the Ti6Al4V3Cu alloys obtained by casting, were processed by a continuous casting process, where liquid metal was solidified with a specific cooling rate, thus, leading to different microstructures, such as primary α phase and α coarse lamellae (transferred from β). According to previous reports, grain refinement can increase electron activity at grain boundaries, which can help the rapid formation of stable passive films, improving corrosion resistance [ 33 ]. Dai et al [ 34 ] proved that the size of the grain has a significant influence on the corrosion rate, and it is proposed that the corrosion rate and grain size show a positive correlation.…”
