Virtual design of formability for Zircaloy-4 sheet through texture control

Microstructure and Mechanical Strength of Surface Ods Treated Zircaloy-4 Sheet Using Laser Beam Scanning

Zirconium alloys have been used as a fuel cladding material for a long time because they have good corrosion resistance and irradiation stability in a reactor environment. However, it was recognized that the severe oxidation and creep ballooning behaviors of zirconium alloy cladding tubes at an accident condition of a nuclear reactor have to be considered to improve nuclear plant safety after t...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Mechanism of anodic oxide film formation on zircaloy-2, zircaloy-4, titanium and niobium (Radio tracer technique)

The kinetics of anodic oxidation of zircaloy-2, zircaloy-4, titanium and niobium have been studied in 0.1M sodium methoxide without and with addition of a millimole of sodium phosphate at a constant current density of 8mA.cm-2 and at room temperature (300 K). the addition of phosphate ions found to improve the kinetics of film formation. This trend and mechanism of anodic oxide film growth is c...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
