Microstructure and thermoelectric properties of bulk and porous n-type silicon-germanium alloy prepared by HUP

Cyril Cayron

The optimization of powders preparation and consolidation process leads to the achievement of a high thermoelectric figure of merit (ZT=1.25 at 800°C) in an n-type silicon-germanium (SiGe) alloy hot pressed at low heating rate. It has been experimentally o ...

Sintering behavior of nano alumina powder shaped by pressure filtration

Mehdi Mazaheri

In the present study, the sintering behavior of a commercial nano alumina powder with an initial particle size of 100 nm was investigated. The shrinkage response of the powder formed by pressure filtration (PF) during non-isothermal sintering was measured ...

Microstructural evolution of a commercial ultrafine alumina powder densified by different methods

Mehdi Mazaheri, Masoud Aminzare

The densification and grain growth of bodies made from a commercial ultrafine alumina powder was investigated. The primary powder was initially subjected to dry (uniaxial cold pressing) and wet shaping (slip casting), followed by conventional (CS)-, two st ...

Effects of thermal loading history on structural adhesive modulus across glass transition

Thomas Keller, Yu Bai

Dynamic Mechanical Analysis was conducted on a polyurethane adhesive at different constant heating rates up to 100°C, covering the glass transition range. Different storage modulus degradation curves were obtained from different heating rates. The differen ...

Ion cyclotron resonance heating with consistent finite orbit widths and anisotropic equilibria

Jonathan Graves, Wilfred Anthony Cooper, Martin Jucker

Minority ion cyclotron resonance heating is studied using the self-consistent numerical model SCENIC. This model includes 3D geometries with full shaping and anisotropic pressure effects, warm contributions to the dielectric tensor and full orbit effects. ...

Sintering behavior of an ultrafine alumina powder shaped by pressure filtration and dry pressing

Mehdi Mazaheri

Master sintering curve (MSC) was used as a practical approach to analyse the sintering behavior of an ultrafine alumina powder. Non-isothermal sintering was carried out at three heating rates. The concept of the MSC has been used to investigate the effect ...

On the heating mix of ITER

Olivier Sauter, Minh Quang Tran, Costanza Zucca, Hartmut Zohm, Frank Rüdiger Wagner

This paper considers the heating mix of ITER for the two main scenarios. Presently, 73 MW of absorbed power are foreseen in the mix 20/33/20 for ECH, NBI and ICH. Given a sufficient edge stability, Q = 10-the goal of scenario 2-can be reached with 40MW pow ...
