Deformation of Zr₄₁Ti₁₄Cu_12.5Ni₁₀Be_22.5 bulk amorphous alloy under isobaric pressure in super-cooled liquid region

【Abstract】 The curve of crystallization transition during continuous heating for the ~Zr_~41 Ti_~14 Cu_~12.5 Ni_~10 Be_~22.5 bulk ~amorphous alloy was measured by means of dilatation(Fully automatic transformation recording/measuring instrument) and X-ray diffraction(XRD) method. The deformation behavior of the alloy at various heating rates in the supercooled liquid region was studied. The results show that the glass transition temperature of the alloy increases slightly and the supercooled liquid region(SLR) increases significantly with increasing heating rate. The deformation amount under isobaric pressure of 1N for the alloy in the SLR increases with increasing heating rate. As the heating rate of the alloy increases from 5 to 100℃/min, the amount of deformation of the alloy increases from 8.3% to 45%.更多还原
