Deformation-induced transformations in Ti60Fe20Co20 alloy

Micro-to-nano-scale deformation mechanisms of a bimodal ultrafine eutectic composite

“…1b. This suggests that the propagation of shear bands along the interface of the primary eutectic colonies is possibly caused by a rotational mechanism of the eutectic colony, similarly to previous investigations on the deformation behavior of Ti-, Fe- and Mg-based BUECs91920. The AFM images obtained from the same area shown in Figs.…”

Five decades of research on the development of eutectic as engineering materials

“…The element Co, having a higher melting temperature than Sn, increases these ternary alloys application temperature with a slight increase in the density (5.6 g/cc). The presence of several intermediate phases in this system offers various possible pathways to design and develop novel microstructures with simultaneous improvement of mechanical properties at room and high temperatures [113][114][115][116]. Samal et al [117] reported the microstructural evolution of a series of hypoeutectic Ti 75 Fe 25-x Co x (0, 5, 10, 12.5, 15, 20), eutectic (Ti 70.5 Fe 29.5 ) 100-x Co x (x = 0, 2, 4, 6, 8 and 10), hyper eutectic Ti 70 Fe 30-x Co x (x = 0, 5, 10, 15, 20, 25), Ti 65 Fe 35-x Co x (0, 10, 15, 17.5, 20, 25) and Ti 60 Fe 40-x Co x (x = 0, 16,18,20,22,24) alloys.…”

Favorable microstructural modulation and enhancement of mechanical properties of Ti–Fe–Nb ultrafine composites

“…In the case of Ti-based nanostructure-dendrite composites with high strength and enhanced deformability, the deformation mechanism is strongly linked to the ultrafine eutectic matrix by nucleation, pinning and multiplication of shear bands during deformation [39]. In addition, the lattice strain, local rotation processes and structural short-range ordering also play a significant role in enhancing the macroscopic plasticity [40][41][42][43][44]. Hence, it is very important to control the microstructural features of ultrafine eutectic composites.…”
