AbstractThe newly designed Ti-based bulk metallic glass (BMG) in which case of fracture behavior was observed 1990MPa to compressive strength with a wide plastic deformation around 7% after process of elastic deformation. This phenomenon can be compared with those of Ti-based alloys and other Ti-based BMGs and indicates high potential to be applied in use. It was evaluated the Ti-based BMG for thermal stability that the reduced glass parameters, ΔTx,Trgand γ, are 79K, 0.50 and 0.38, respectively. In addition, it reveals high activation energies for crystallization in which are estimated toEx1= 291.77 ±9.71 kJ/mol,Ex2= 588.77 ±28.88 kJ/mol andEx3= 330.26 ±3.61 kJ/mol on kissinger plotting in this study.

Abstract Zr-based Bulk metallic glasses exhibit incredible corrosion resistance and glass forming ability, however, these properties need further enhancement to meet the practical use. In this study, Zr63Fe2.5Cu23Al11.5, a new type of Zr-based bulk metallic glass was fabricated. Potentiodynamic polarization techniques were used to measure the corrosion resistance of this alloy. Furthermore, crystallization behavior and kinetics of Zr63Fe2.5Cu23Al11.5 bulk metallic glass were investigated by using differential scanning calorimetry of non-isothermal model. Kissinger and Ozawa methods were used for calculating activation energies of crystallization and the mechanism of crystallization was analyzed by Johnson-Mehl-Avrami-Kolmogorow methods. The results suggest that this specified metallic glass system possesses a relatively high thermal stability and glass forming ability. Moreover, the crystallization procedure is mainly dominated by nucleation with an increasing rate. The study demonstrates that the slight composition adjustment of Zr–Fe–Cu–Al system bulk metallic glass can make a considerable contribution to higher glass forming and thermal stability as well as corrosion resistance.

The effects of small amounts of Si on the glass-forming ability, thermal stability and mechanical property of a TiZrCuPdSn bulk metallic glass were investigated. The addition of Si caused the decrease of glass-forming ability and the increase of the supercooled liquid (SCL) region. With 2 at.% Si addition, a significant SCL region of 80 K was obtained, which indicated high thermal stability of the glassy alloy and was in favor of secondary working by viscous flow deformation. With increasing Si content, the plasticity decreased.
