Corrosion fatigue cracking in fossil-fueled boilersSpringer Science and Business Media LLC - - 1987
H. J. Westwood, W. K. Lee
Corrosion fatigue in boiler tubing is a major cause of forced outages in
conventional (fossil-fueled) electricity generating plants and similar damage in
larger, thick section boiler components is also of concern. The phenomenological
aspects of corrosion fatigue cracking are described and the current theoretical
understanding of the crack initiation and growth processes is reviewed. A need

Thermionic emission characteristics of sintered tungsten-rhenium alloysSpringer Science and Business Media LLC - Tập 9 - Trang 353-365 - 1988
M. L. Ramalingam, S. Snir, D. L. Jacobson
Multiconstituent refractory metals, capable of operating at high temperatures,
provide greater heat rejection, hence lighter, denser and more efficient
thermionic energy converters. Thermionic energy conversion offers unique
advantages such as increased power levels and densities which are prime
requisites for crucial future space applications. Investigation of these
multiconstituent metals for ef... hiện toàn bộ
Production processes of iron oxides for soft ferritesSpringer Science and Business Media LLC - Tập 13 - Trang 135-140 - 2013
Masao Tsuzaki, Katashi Takaki, Fumiaki Yoshikawa, Masashi Nakamura, Tetsuo Kuriyama
The production techniques used in producing iron oxides from pickling liquors
have become very important since the high grade soft ferrites are required in
recent years. The chemical and physical characteristics of iron oxide,
especially silicon and chloride contents and compressed and sintered densities,
have large effects on the quality of soft ferrite. Their reduction and control
methods and th... hiện toàn bộ

H. H. Stadelmaier
Excepting Co-Sm, which may be considered a mature technology, recent permanent
magnet research has proceeded along four lines, (a) improvement of the
properties of Fe-Nd-B by alloying additions and processing, (b) the exploration
of other alloy systems that feature the tetragonal compound of the Fe14Nd2B
type, such as Fe-Pr-B and the carbides, (c) the systematic study of new magnetic
compounds, su... hiện toàn bộ
