“…[13][14][15] X-ray diffraction was discussed to show no evidence for the presence of crystalline phase. 15) On the other hand, Nagahama et al 16) recently could convincingly show that depending on the cooling rate fully amorphous or partly crystallized Cu 60 Zr 30 Ti 10 are prepared.…”

Phase Separation and Crystallization in Cu-Zr Metallic Glasses

The structural behavior of rapidly quenched Cu-Zr amorphous alloys was analyzed. High energy X-ray diffraction patterns and atomic pair correlation functions exhibit monotonic changes with composition. The experimental results can be well described by a solid solution-like replacement of Cu and Zr atoms in the whole composition range. No indications are observed that would support the existence of phase separation in the supercooled liquid state of the binary Cu-Zr alloys. For Cu 60 Zr 30 Ti 10 and Cu 60 Zr 20 Ti 20 bulk metallic glasses the formation of ultrafine nanostructures are proven upon heating. The transformation starts below the glass transition temperature. Phase separation in Cu-Zr-Ti bulk metallic glasses is related to primary crystallization.

“…However, if nanocrystal/amorphous composite is formed during solidificatin, it can lead to enhancement of the plastic strain as reported in Cu-Zr-Ti BMG. 19) Melt temperature is also very much important as shown in Fig. 8.…”

Quinary Zr-based alloy compositions with improved glass forming criteria have been sought and the glass forming ability (GFA), thermal stability and mechanical properties of these alloys have been investigated. Monolithic amorphous structure has been confirmed for all compositions in 5 mm rods prepared by a Cu-mold casting method. They also show large plastic strain maximum of about 12% under uniaxial compression test with yield stress of about 2000 MPa. The compressive plasticity of the cast rods was found to be influenced by the casting temperature to a great extent.

“…Correctly chosen quaternary alloys have even higher GFA. 18,19) The assolidified structure of Cu-Zr-Ti glassy alloys 20,21) has been studied. The devitrification behavior of the binary Cu-Zr alloys 22,23) including Cu 50 Zr 50 alloy, as well as the ternary Cu-Zr-Ti, [24][25][26][27][28] quaternary Cu-Zr-Ti-Ni and quinary Cu 47 -Ti 33 Zr 11 Ni 8 X 1 (X ¼ Fe, Si, Sn, Pb) alloys 29) glassy alloys has been also studied in detail.…”
