Amorphous and icosahedral phases in Ti–Zr–Cu–Ni–Be alloys

Formation of high-strength nano-micro duplex structures in electrodeposited Ni-based alloys

“…However, use of these nanocrystalline alloys as structural components in practical application is limited because of their severe brittleness in tensile testing mode. Similar failure has also been observed in monolithic glassy metals, and an icosahedral phases [2]. A ductile bcc phase [3] distributed in a glassy matrix significantly improved their deformation behavior.…”

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

“…In 1998, the first Ti-based BMG was successfully prepared by a copper mold casting in a Ti-Cu-Ni-Sn alloy system [39]. 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].…”

Effects of Effective Dendrite Size on Tensile Deformation Behavior in Ti-Based Dendrite-Containing Amorphous Matrix Composites Modified from Ti-6Al-4V Alloy

“…[1][2][3][4][5] They are also accepted as world-wide leading-edge structural materials, which have become available by continuous improvements in manufacturing processes. However, the manufacturing costs are still high because of relatively expensive alloying elements and the need of vacuum equipment, and problems such as brittle fracture need to be solved.…”
