The microstructures of Ti-6Al-4V following laser processing depend primarily on the phase transformation of β to α, but their development is constrained by the rapidly changing temperature in the small fusion zone. In-situ synchrotron X-ray diffrac

A higher-basicity mold flux (binary basicity 1.74) for peritectic grades showed similar solidification behavior to conventional high-basicity fluxes. Upon solidification of the mold flux onto a water-cooled copper probe, interfacial roughness at the

In this study, an improved water-cooled copper probe was used to obtain solidified films of a mold flux used to cast peritectic steel. Different bulk temperatures of molten mold flux and different probe immersion times were used. The results reveal t
