Texture and Creep Anisotropy in Zirconium AlloysMaterials Science Forum -  Tập 539-543  - Trang 3377-3382
Indrajit Charit, K.L. Murty
Zirconium (Zr) alloys are best known for their use in nuclear reactor applications. A
hexagonally close-packed structure with a low c/a ratio and very limited slip systems leads to strong
textures in these alloys during fabrication processes. These alloys are used in cladding applications
for encapsulating fuel pellets, and undergo various stress conditions in-service. Hence, it is
necessa......  hiện toàn bộ

Institute of Space and Astronautical Science (ISAS/JAXA) in collaboration with
Mitsubishi Heavy Industries (MHI) has developed fuel and gas tanks for reaction control system and
orbital control system of satellites; A tank is fabricated through welding of two thin, hemi-spherical or
conical parts, which are fabricated by superplastic blow forming. Mass-productivity is not an
important fact......  hiện toàn bộ

 Prediction of Cutting Forces during Turning PA66 GF-30 Glass Fiber Reinforced Polyamide by Soft Computing TechniquesMaterials Science Forum -  Tập 766  - Trang 37-58
Nikolaos A. Fountas, Ioannis Ntziantzias, John D. Kechagias, Aggelos Koutsomichalis, J. Paulo Davim, Nikolaos M. Vaxevanidis
In the present paper the influence of the main cutting parameters on process performance during longitudinal turning of PA66 GF-30 Glass Fiber Reinforced Polyamide is investigated. The selected cutting parameters are cutting speed and feed-rate whilst depth of cut is kept constant. As outputs (responses), cutting force components Ft...  hiện toàn bộ
