During the extrusion of aluminum alloys profiles using porthole dies, temperature material in welding chamber is one crucial parameters determining quality longitudinal welds. In order to extend permissible range, billets intended for this process should be characterized by maximum attainable solidus temperature. Within present work, homogenization AlZnMgCu DC-cast (Direct Chill-cast) was inves...

Drying is a common pharmaceutical process, whose potential to modify the final drug and/or dosage form properties is often underestimated. In the present study, pellets consisting of the matrix former calcium stearate (CaSt) incorporating the active pharmaceutical ingredient ibuprofen were prepared via wet extrusion and spheronization. Subsequent drying was performed by either desiccation, flui...

Cereal Chem. 72(6):559-563 Films were prepared by casting and drying alkaline aqueous filmelongation at break (E). TS values ranged from 1.4 to 3.9 MPa and E forming solutions of soy protein isolate (SPI). Four additional types of values ranged from 83 to 152%. Water vapor permeability of the films films were made by combining SPI with poly(ethy1ene oxide) (PEO) in ranged from 3.0 x to 4.0 x gl...

This article reviews the advances in additive manufacturing of magnetic ceramics and alloys without rare-earth elements. Near-net-shaped permanent magnets with varying shapes dimensions overcome traditional limitations cast, sintered, bonded magnets. The published articles are categorized based on material types 3D printing techniques. Selective laser melting electron beam were predominantly us...

The shear behavior of polymers obtained by means of devices such as capillary and cone-and-plate rheometers is commonly used to assess their processing performance and as a characterization tool. However, the number of instances when two polymers have the same shear properties but perform differently during certain types of processing operations (e.g. film blowing and sheet extrusion) indicate ...

Porosity is a major concern in the production of light metal parts. This work aims to identify some of the mechanisms of microporosity formation in magnesium alloy AZ91. Microstructure analysis was performed on several samples obtained from gravity-poured ingots in graphite plate molds. Temperature data during cooling was acquired with type K thermocouples at 60 Hz at three locations of each ca...

There is an urgent need for a simple and effective method to manufacture flexible sensors composed of liquid metal. Gallium (Ga) metal has become ideal conductive material due its high conductivity, low melting point, flow characteristics. In this paper, Ga directly written on the polyvinyl alcohol (PVA) film through driving mode piston extrusion; then, wire transferred sealed with silica gel. ...
