The improvement of thermal efficiency of power plants has provided the incentive for the
development of the martensitic–ferritic 9–12% Cr creep-resistant steels. Good progress has …

Dissimilar welds between ferritic creep-resistant steels and austenitic stainless steels in
power plant service are known to fail prematurely due to a large difference in their thermal …

At moderately high temperature sections of Advanced Ultra Super Critical (AUSC) boilers,
welding of superalloys to austenitic steels is inevitable owing to economic aspects of boiler …

Advanced ultra-supercritical (A-USC) is a term used to designate a coal-fired power plant
design with the inlet steam temperature to the turbine at 700 to 760C (1292 to 1400F) …

Creep rupture can happen in two ways, brittle and ductile creep rupture. Brittle creep rupture
of austenitic stainless steels proceeds with the nucleation, growth and coalescence of grain …

Creep strength enhanced ferritic (CSEF) steels are used in advanced power plant systems
for high temperature applications. P92 (Cr–W–Mo–V) steel, classified under CSEF steels, is …

Microstructure evolution and hardness were evaluated at the interface of two friction-welded
transition joints between P91 and AISI 304 fabricated applying Inconel interlayers, viz. single …

Microstructural investigations and stress rupture tests were performed on specimens
extracted from the columnar grain sections of large blocks of cast alloy 625. Metallographic …

This paper overviews the effects of some precipitates in Fe–Ni base boilers materials. The
volume fraction of these precipitates is usually below 10 for maintaining the microstructure …

This paper presents two models of fluid heating in waterwall tubes of supercritical steam
boilers. The models are named 1D/2D and 1D/3D. The models are formulated and …
