To improve the manufacturing efficiency of ceramic MOX fuels, wet processes, such as extrusion, are studied a novel production method. The flowing behavior, is essential to obtain smooth and defectless rods. This work provides study on rheological properties paste assesses possibility produce nuclear fuel by extrusion. Surrogate powders UO2 PuO2 were used, respectively TiO2 Y2O3. A with 40.9%vo...

one of the most important parts of power transmission in automotives is c.v. joint, which consists of four components where exterior bowl is one of them. due to its complexity, and importance in automobile and existence of high stresses, forging process is the only cost effective method of production. hence, the best method of production of this part is forging process. the exterior part of c.v...

Introduction Bar extrusion is a process in which a block of metal (billet) is forced to flow by compression through a tool (die) opening of a smaller crosssectional area than that of the original billet. There are two basic types of bar extrusion: direct and indirect. The most important and common method used is the direct extrusion (Lange 1988). Figure 1 shows the principle of direct bar extru...

Contractile rings consisting of actin filaments and myosin-2 have long been known to power cytokinesis, but recent work has shown that single-cell and multicellular actomyosin rings participate in processes ranging from wound healing to extrusion of apoptotic cells from epithelia.

In this study, five microcrystalline cellulose (MCC) grades were physically characterized and their extrusion-spheronization behaviours were characterized in terms of water requirements and pellet shape profiles. It was found that the MCC grades differed significantly in the physical properties investigated. Physical properties of MCC were found to influence the water requirement for extrusion-...

The ZK61 alloy rods with different grain sizes and crystallographic texture were successfully fabricated by cyclic extrusion and compression (CEC). Their room-temperature tension & compression yield strength displayed a significant dependence on grain size and texture, essentially attributed to {10-12} twinning. The texture variations were characterized by the angle θ between the c-axis of ...

Abstract In this article, we review some recent theoretical results about intrusion and extrusion of non-wetting liquids in out cavities nanotextured surfaces nanoporous materials. Nanoscale confinement allows these processes to happen at conditions which significantly differ from bulk phase coexistence. particular, the pressure a liquid penetrates exits is interest for many technological appli...
