WebAt the ‘melt connectivity transition’ (MCT) there is a large loss of strength and reduction in effective viscosity by about two orders of magnitude. The MCT is also important for the development of matrix permeability for melt flow [ 56] and for faster diffusive transport for mush deformation by dissolution–precipitation mechanisms.
