摘要	Twin-roll casting (TRC) technique has been proven to be a feasible method for producing metal strips. In this work, a new laboratory-scale twin-roll caster capable of producing long and straight metallic glass composite (MGC) strips was designed and manufactured. The new twin-roll caster generated three types of Ti-based MGC strips (BT30, BT48, and BT60) with varying in situ beta-Ti volume fractions at temperatures of 1273 and 1473 K. A series of three-point bending tests were conducted on the Ti-based MGC strips. The results demonstrate that the elements with higher melting temperatures are richer in the middle of the strips rolled at a higher temperature, leading to uneven distributions of composition in the middle and the edge of the strips. The mechanical behavior of MGC strips is greatly influenced by residual stress induced by the thermo-mechanical effect during the TRC process. The large beta-Ti crystals with lattice distortion during bending greatly restrict the deformation band, leading to enhanced strength but poor plasticity of the BT48 strip. In comparison, due to the high fraction of crystals with large released crystallization energy, the BT60 strips lead to the severe relaxation of the glassy matrix and cause extreme brittleness. These findings not only provide a new method for preparing MGC strips but also deepen our understanding of the mechanical properties of MGC strips.
