Ductile fine-grained Ti–O-based composites with ultrahigh compressive specific strength fabricated by spark plasma sintering

Bulk amorphous Al85Fe15 alloy and Al85Fe15-B composites with amorphous or nanocrystalline-matrix produced by consolidation of mechanically alloyed powders

“…For Ti-based bulk metallic glasses (BMG) the specific yield strength in the range 380e450 kNm/kg, depending on the alloy composition, was found [21], while for Ti-Zr-Cu-Ni-Sn BMG, the value of 357.6 kNm/kg was reported [22]. Recently, fine-grained Ti-O-based composites with ultrahigh specific strength in the range 462e542 kNm/kg were fabricated by spark plasma sintering [23]. In the light of the cited results, we conclude that the specific yield strength of the materials produced in this work is relatively high.…”

“…Moreover, tailored microstructure could be obtained by controlling sintering and crystallizing of amorphous titanium alloy powder . Several studies achieved fine and ultrafine equiaxed grained composite microstructure showing enhanced mechanical properties …”

Nanocrystalline or amorphous matrix Al60Fe15Ti15(Co/Mg/Zr)5–5%B composites produced by consolidation of mechanically alloyed powders – lightweight materials with high hardness

“…For Ti-based bulk metallic glasses (BMG) the specific yield strength in the range 380e450 kN m/kg, depending on the alloy composition, was found [36], while for TieZreCueNieSn BMG, the value of 357.6 kN m/kg was reported [37]. Recently, fine-grained TieObased composites with ultrahigh specific strength in the range 462e542 kN m/kg were fabricated by spark plasma sintering [38]. Al 86 Ni 7 Y 4.5 Co 1 La 1.5 bulk metallic glass with ultrahigh specific strength 334 kN m/kg was reported lately as well [6].…”
