(a) Outer appearance of the composite sample with the outer Zr50.7 alloy and the inner Zr51 alloy fabricated using a liquid-solid joining process with the inset illustrating the dimension of the joint, (b) DSC curves obtained from the inner Zr51 and outer Zr50.7 alloy parts of the welded sample at a constant heating rate of 20 °C/min, (c) SEM image obtained from the cross section of the Zr51/Zr50.7 alloy joint with the inset showing the high magnification SEM of the interface and (d) Nano-hardness profile across the interface of the welded Zr51/Zr50.7 alloy joint (the position, x = 0 corresponds to the interface).
