Effect of B addition to hypereutectic Ti-based alloys

Enhancement of mechanical properties in a Fe81Nb9B10 ultrafine-eutectic composite with in-situ polygonal pro-eutectic and encapsulating eutectic structure

“…1(b). In addition, we identified that the dimple patterns is provoked from the rotational motion of spherical eutectic colonies, as shown in previous reported literatures [5,28,29]. They suggested that the rotational motion of spherical or round shape microstructural architectures can effectively lead to dissipate a stress concentration and to hampering the shear localization.…”

<i>In Situ</i> Formation of Ti Matrix Composites Reinforced Nanometric TiC by Powder Metallurgy Technique

“…Linear work hardening is a well-established phenomenon for the deformation of another hexagonal metal-magnesium, due to athermal hardening by accumulation of dislocations [10,13,14]. Such a level of strength and ductility makes as-sintered novel Ti-TiC composites competitive with other advanced Ti-based materials [15,16,17,18].…”

Self-assembled, aligned TiC nanoplatelet-reinforced titanium composites with outstanding compressive properties

“…This work reports on the fabrication and characterization of a nanometric Ti MMC which contains locally aligned but macroscopically randomly orientated TiC reinforcements through a novel approach which combines conventional powder metallurgy with nanochemistry. The resulting as-sintered nanometric Ti-TiC MMCs show outstanding compressive properties, superior to all other advanced Ti materials reported to date, including Ti-based bulk metallic glasses [20][21][22][23][24][25][26].…”

“…including ultrafine-grained Ti obtained by severe plastic deformation [20], as-cast hypereutectoid Ti alloys [21], composites [22], Ti bulk metal glasses (BMGs) [23,24] or BMG-based composites [26], and nanostructured Ti MMCs [25]. Figure 4b compares the compressive properties of all these Ti materials.…”
