The invention discloses a
metal glass
composite material with high-
oxygen content and a preparation method thereof. The expression of the
atomic ratio of the material is Zr[a]Ti[b]M[c]Cu[d]Ni[e]Be[f]O[g], wherein M is one of
niobium (Nb),
vanadium (V) or
hydrogen fluoride (Hf), a is larger than or equal to 10 and smaller than or equal to 70, b is larger than or equal to 10 and smaller than or equal to 70, c is larger than or equal to 4 and smaller than or equal to 15, d is larger than or equal to 2 and smaller than or equal to 12, e is larger than or equal to 0 and smaller than or equal to 10, f is larger than or equal to 5 and smaller than or equal to 15, g is larger than 0 and smaller than or equal to 15, and a plus b plus c plus d plus e plus f plus g equals 100. The preparation method includes the steps of
smelting master
alloy ingots,
casting master
alloy profile, placing the master
alloy profile into a
crucible to heat and smelt, carrying out overheating treatment melting impurities, lowering temperatures to
solid and liquid two-phase region, carrying out semi-
solid treatment so that
oxygen elements segregate and are solute in separated beta-
zirconium (Zr) or beta-
titanium (Ti) in a
solid mode, controlling the shape and size of the separated solid and liquid, carrying out semi-solid progressive solidification to form the large-size
metal glass
composite material of high strength and high
toughness. The
large size of 30 millimeters
metal glass
composite material of the high strength and the high
toughness with is prepared, and is remarkable in
processing solidification property and good in tensile strength and
plasticity.
