Doping-induced formation of bulk nanocrystalline alloy from metallic glass with controllable microstructure and properties

Studies of nanostructuring in cesium magnesium tungsten phosphate glass

“…A question then arises which mechanism leads to the formation of nanocrystals and why the crystallization is hindered when only about 30.5 ± 1.3% of WO 3 is used. One of the possible mechanism is known to be the extremely high nucleation rate and small growth rate and another is the phase separation on extremely fine scale in supercooled liquid [1,[33][34][35][36][37]. Actually, the nanoscale separation in supercooled liquid is a common phenomenon in many materials exhibiting nanocrystallization.…”

Rare earth based bulk metallic glasses

“…Table 1 lists the properties of RE elements and the typical REBMGs. Later on, extensive work was carried out on the crystallization, glass transition, liquid fragility, GFA, thermal stability, the mechanical and physical properties, elastic properties and their response to temperature, frequency and pressure [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47].…”

Influence of low-temperature annealing on magnetic properties of (Nd0.625Ni0.375)85Al15 metallic glass

“…Different from S3, only an endothermic behavior was detected during the heating process of S2. Although the quenched-in nuclei with net magnetic moments were identified in S1 [5], as widely observed in rare-earth-based materials [11,12], the growth of the nuclei and the nucleation of the amorphous matrix are thought to be negligible in S2, since at a relatively lowtemperature about T g , it always takes much longer time to crystallize during the isothermal process. For S2, since the amorphous structure keeps maintained, the spin-glass state is primarily influenced by the atomic and site disorders, which bring about a competition of the randomly distributed exchange interactions between Nd-Nd, Nd-Ni and Ni-Ni bondings.…”
