The effect of in addition on the glass-forming ability in Cu-Ti-Zr-Ni-Si metallic glasses

Abstract

The effect of In substitution for Ni on the glass forming ability has been studied in Cu47Ti33Zr11Ni8-xIn xSi1 (x = 0, 2, 4, 6, 8) alloys by using thermal analysis and X-ray diffractometry. Partial substitution of Ni by In in Cu 47Ti33Zr11Ni8Si1 promotes the glass forming ability. Cu47Ti33Zr11Ni 6In2Si1 bulk metallic glass with diameter of 6 mm can successfully be fabricated by Cu-mold injection casting method. ΔTX and K parameter show a good relationship with the measured maximum diameter of the amorphous specimen.
