A partial melt undergoing large scale deformation is shown to be unstable with respect to small scale redistribution of melt, provided the shear viscosity of the matrix depends on melt fraction. In the physically realistic case where melt "softens" the matrix, melt migrates along the direction parallel to the axis of minimum compressive stress and accumulates in "veins" (melt-rich lenses). The ...

Hot-melt extrusion is one of the most widely applied processing technologies in the plastic, rubber and food industry. Today this technology has found its place in the array of pharmaceutical manufacturing operations. Melt extrusion process are currently applied in the pharmaceutical field for the manufacture of a variety of dosage forms and formulations such as granules, pellets, tablets, supp...

predicted effects, but more complete sample suites yielding detailed Modeling of equilibrium reactive melt transport in the mantle, temporal–compositional variations of clearly cogenetic lavas are including the effects of mineralogic reactions and changes in porosity needed to test the petrogenetic significance of reactive melt transport in the solid matrix, provides a series of robust predicti...

Abstract Graphene-based polymer composites with improved physical properties are of great interest due to their lightweight, conductivity, and durability. They have the potential partially replace metals ceramics in several applications which can reduce energy cost. The obtained graphene-based often linked way graphene is dispersed matrix. Preparation techniques like solution mixing, melt blend...

Poly(lactic acid) (PLA) stands out as the most promising biodegradable alternative to conventional petrochemical-based polymers for manufacturing of high-performance materials applied in medicine, pharmacy, food, textile, and electronic industry. This review was aimed present up-to-date technologies PLA processing including melt blending molding, hot extrusion, 3D printing, foaming, impregnatio...

Halloysite nanotubes (HNTs) were incorporated into an EPDM/SBR rubber/styrene-butadiene rubber (SBR) composite by melt blending of HNTs the blend. The mechanical properties, abrasion and swelling resistance ranging from 2 parts per hundred (phr) to 10 investigated in base rubber. Tensile strength, 100% modulus (modulus at elongation), elongation break tear strength evaluated ambient temperature...

[1] Anelasticity and diffusion creep viscosity of partially molten rock analogue were measured experimentally at various melt fractions (0.0025–0.04). The presence of even a small quantity of melt phase causes a significant increase in attenuation and dispersion, and decrease in viscosity (melt effect). Similar changes are additionally caused by the presence of a secondary solid component (chem...
