NANOSTRUCTURED MATERIALS Progress in hydrostatic extrusion of titanium
At the beginning of the present century it has been demonstrated that nanocrystalline titanium (NC-Ti) can be fabricated by hydrostatic extrusion (HE) which is one of the severe plastic deformation method. NC-Ti obtained in such a way exhibited excellent mechanical properties. The influence of HE on the microstructure and mechanical properties of titanium Grade 2 was first analyzed in 2005. In ...
متن کاملExperimental and Finite Element Analyses of the Hydrostatic Cyclic Expansion Extrusion (HCEE) Process with Back-Pressure
It is generally known that severe plastic deformation processes with back pressure not only apply higher hydrostatic stress and more deformation compared to what a regular process can apply to a workpiece but also prevent surface defects in the workpiece during the process. Hydrostatic cyclic expansion extrusion (HCEE) was developed recently for processing long ultrafine-grained metals and allo...
متن کاملFUZZY SOFT SET THEORY AND ITS APPLICATIONS
In this work, we define a fuzzy soft set theory and its related properties. We then define fuzzy soft aggregation operator that allows constructing more efficient decision making method. Finally, we give an example which shows that the method can be successfully applied to many problems that contain uncertainties.
متن کاملOrthodontic extrusion: periodontal considerations and applications.
Human teeth erupt naturally to compensate for tooth wear and tear. When a subgingival lesion such as crown fracture occurs, the general practitioner must consider orthodontic extrusion of the tooth to allow for prosthetic rehabilitation. However, because this therapeutic approach is not appropriate in all cases, each tooth must be carefully analyzed before treatment. The amount of force applied...
متن کاملFinite Element Simulation of Hydrostatic Extrusion Process to Produce Thin Bimetallic Parts
The hydrostatic extrusion is a new method of extrusion process. The most important advantage of this method is reduction of friction and close tolerance for the coating thickness. In this study, the hydrostatic extrusion simulation of bimetallic wires has performed using of finite element method. In the following the advantages of hydrostatic extrusion compared to the direct extrusion are prese...
