“…[7][8][9][10][11][12][13]. After decades of research and development, compared with previous crystal materials, it has been found that amorphous alloys have higher strength, hardness, high wear resistance, elastic limit and fracture toughness, high corrosion resistance, excellent low magnetic loss, conductivity and other characteristics [14][15][16][17][18][19][20][21], and developed a series of bulk amorphous alloy systems, such as Fe-base, Zrbase, Pa-base, Al-base, Ti-base system, etc. These characteristics of BMGs make it have widespread application space in sports equipment, automobile manufacturing, medical, military, aerospace and other fields [22][23][24].…”

The effects of different process parameters on the microstructure and mechanical properties of Zr-based bulk metallic glass were studied by using four factors and four levels of orthogonal experiment. Through the observation and analysis of the X-ray diffraction pattern, room temperature compressibility, microhardness distribution and transmission electron micrograph of the [Zr0.72-x(Cu0.59Ni0.41)0.28+x]88-yAl12+y (atomic percent) amorphous alloy with different process parameters, the results show that the compressive strength of the amorphous alloys with composition of [Zr0.73(Cu0.59Ni0.41)0.27]88Al12 and [Zr0.73(Cu0.59Ni0.41)0.27]87Al13 amorphous alloy under the corresponding processing parameters has reached 2411MPa and 1993MPa, and the plastic strain of the alloys is 33.8% and 19.3%. At the same time, through orthogonal analysis, in the four process parameters, the superheat temperature of the melt during the preparation of the alloy mainly affects the compressive strength of the alloy, while the cooling rate of the melt during the preparation of the alloy has a great influence on the plastic properties of the alloy.

The reduced glass transition temperature (T rg ) and fragility index (m) are both used to predict the critical cooling rate (R c ). When either T rg or m is individually used to predict log 10 (R c ), a large deviation occurrs in the prediction of log 10 (R c ) because both of the corresponding correlations have low coefficients of determination (R 2 ). The R 2 value increases from either 0.33 (by using only T rg ) or 0.68 (by using only m) to 0.91 by using both T rg and m. Therefore, the glass-forming ability (GFA) is estimated more accurately when T rg and m are both applied to predict log 10 (R c ) through a binary linear regression analysis.
