Following the recent success of hot-melt extrusion in the pharmaceutical field, monitoring and control are increasingly applied. In this study, a mathematical model consisting of mass and energy balance partial differential equations is developed and parameters related to material transportation are inferred from experimental data collected from a pilot plant. This data is relative to the outpu...

Thermoreversible food materials are suitable for hot-extrusion 3D printing (HE-3DFP) to customize designs and enable on-demand production. A challenge of HE-3DFP is control the material phase transition such that it melts allow flow extrusion rapidly solidifies afterwards obtain stable printed structures. We here report on use thermal imaging simultaneously monitor cooling deformation common th...

Al-Mg alloys were fabricated by hot extrusion process after vacuum + argon-protected casting. The effects of Sc microalloying on microstructure and properties as-extruded Al-5Mg alloy studied. results show that 2 containing is partially recrystallized during extrusion, resulting in the structure consisting 21.8% equiaxed 78.2% fine banding structure. grain size about 5.31 μm, which 83.3% finer ...

Mg-Bi binary alloys with concentrations of 1, 3, 6, and 9 wt% Bi ternary Mg-9Bi-2.5Zn alloy were prepared by casting hot extrusion. The results show that alloying refined as-cast grains Mg the refinement efficiency is in between Al Zr. It was also found a critical value for area fraction constituent 3 2 particles seems to appear, which influences dynamic recrystallization mechanism during This ...
