Effect of process induction on densification behavior, microstructure evolution and mechanical properties of Ti-5Al-2.5Sn ELI fabricated by laser powder bed melting

Effects of build direction and microstructure on fatigue crack growth behavior of Ti6Al4V fabricated by laser powder bed fusion

“…The crack break zone of Figure 9A3-D3 shows denser and deeper toughness dimples than the as-built specimens, indicating that better plasticity and toughness were obtained in Ti6Al4V after annealing treatment. 44 In addition, a higher number of pore defects and disintegration surfaces has been observed in Figure 9A3-D3, which are the main reason for the larger crack deflection in the crack break zone of the heat-treated specimen.…”

Zinc based biodegradable metals for bone repair and regeneration: Bioactivity and molecular mechanisms

“…In contrast to Fe-based BMs, the degradation products released from Zn-based BMs can be safely metabolized and eliminated, at least in animal models in vivo [ 21 , 25 ]. Zn-based implants for bone repair and regeneration, such as internal fixation materials, scaffolds, and barrier membranes, have been developed and examined using various fabrication techniques, including casting, powder metallurgy, extrusion, and additive manufacturing [ 26 , 27 ]. To date, numerous in vivo studies have been conducted to evaluate the effectiveness and safety of Zn-based BMs for bone repair and regeneration.…”
