Centimeter-scale-diameter Co-based bulk metallic glasses with fracture strength exceeding 5000 MPa

Review on the Research and Development of Ti-Based Bulk Metallic Glasses

“…Encouraged by this success, with the effort of scholars all over the world, a number of Ti-based BMGs, such as Ti-Cu-Ni [40,41], Ti-Zr-Be [42,43], Ti-Zr-Cu-Ni-Sn [44,45], Ti-Zr-Cu-Pd-(Sn, Si, Nb) [46][47][48][49][50], Ti-Zr-Cu-Ni-Be [51][52][53], Ti-Zr-Hf-Cu-Ni-Si-Sn [54], and Ti-Cu-Zr-Fe-Sn-Si-(Ag, Sc) [55][56][57], have been developed over the last few decades. Figure 1 shows the maximum diameters for glass formation obtained in different alloy systems and the year in which they were discovered [8,[58][59][60][61][62][63][64][65][66][67][68][69][70][71][72][73]. Compared with other alloy systems (e.g., Zr-, Pd-, Mg-, Fe-, Co-, Ni-, and Cu-based So far, the largest known critical diameter for Ti-based BMGs has been over 50 mm in the Ti-Zr-Cu-Ni-Be [72] and Ti-Zr-Cu-Fe-Be [73] quinary alloy systems.…”

“…Maximum diameters of the bulk metallic glass (BMG) rods achieved in different alloy systems and the years in which they were discovered. Data are taken from [8,[58][59][60][61][62][63][64][65][66][67][68][69][70][71][72][73].…”

Amorphous alloys — A kind of promising high-performance materials

“…The result is a delightful one. We have 17 papers collected in this special issue, which cover broad areas of amorphous alloys, including atomic packing and clusters formation in amorphous alloys [1-3], fragility in glass-forming liquid [4], effects of alloying elements on the glass forming ability of different alloys [5][6][7], deformation behavior and improved mechanical property of amorphous alloys [8][9][10][11], glass-based composites [12,13], high strength metallic glass [14] and functional properties of metallic glasses [15][16][17].…”

Synthesis of CoCrMoCB bulk metallic glasses with high strength and good plasticity via regulating the metalloid content

“…Co-based bulk metallic glasses (BMGs) possess high strength and hardness, good resistance to corrosion and oxidation [1][2][3][4][5][6], thus making them promising structural materials. Nevertheless, the practical applications of Co-based BMGs are hindered by the low glass-forming ability (GFA) and the poor macroscopic plastic deformation [7].…”
