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
factor but t... hiện toàn bộ

NiTi alloys with equiatomic composition of NiTi have the highest technological
interest for its potencial application in differents areas such as biomedical,
naval, aerospace, nuclear, automobilist , robotic,etc. In this work , it was
used a 50Ni50Ti at % powder mixture, comercially pure, prepared by mechanical
alloying in a Attritor with the following conditions: the milling speed and the

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, FV and Fr were selected. Test specimens in the form of
round bar... hiện toàn bộ
Processing and Characterization of Inconel 625 Nickel Base SuperalloyMaterials Science Forum - Tập 830-831 - Trang 38-40

Nickel-based superalloy Inconel 625 is widely used in aeronautical, aerospace,
chemical, petrochemical and marine applications due to its good mechanical
properties, weldability and resistance to high temperature corrosion on
prolonged exposure to aggressive environments. It is a solid solution
strengthened medium strength superalloy, which contains chromium, molybdenum and
niobium as alloying add... hiện toàn bộ
