چکیده انگلیسی
Low-cost TiZr-base bulk metallic glasses (BMGs) (Ti36.1Zr33.2Ni5.8Be24.9)100-xCux (x=5,7and9)witha maximum size of over 50 mm in diameter were developed by optimizing the alloy composition. The idea is initiated by selecting a particular microstructure comprising primary β-Ti dendrite and amorphous phase. Afterwards, based on this composition of amorphous phase, a class of TiZr-base bulk metallic glasses was designed step by step to reach the optimum composition range. The glass transition temperature (Tg), initial crystallization temperature (Tx) and width of supercooled region (ÎT)of(Ti36.1Zr33.2Ni5.8Be24.9)91Cu9 BMG are 611, 655 and 44 K, respectively. The (Ti36.1Zr33.2Ni5.8Be24.9)91Cu9 BMG exhibits low density of5.541 g·cmâ3 and high compressive fracture strength of 1800 MPa, which promises the potential application as structural materials.
