TL;DR: In this article, a laser-melted layer of about 8 μm thick was formed using a pulse energy of 8 J/cm2, and the original grain boundaries of the wrought structure and most of the coarse constituent particles were removed.

TL;DR: McEvily et al. as discussed by the authors present a comprehensive reference work for materials scientists concerned with stress corrosion cracking and corrosion fatigue, which includes over 500 stress/cracking time curves, S/N curves, and other graphical data.
Abstract: Use this new book to find the effects of various corrosive media and processing variables on the stress corrosion cracking and corrosion fatigue characteristics of ferrous and nonferrous alloys. There are over 500 stress/cracking time curves, S/N curves, and other graphical data. An extensive introductory article explains stress corrosion cracking, corrosion fatigue, and related test methods and results. Most curves appear independently, and represent a single alloy in a given condition and environment. In cases where the curveAs significance may not be obvious, explanatory text is included. The major alloy groups covered include aluminium, copper, nickel, titanium and other nonferrous alloys. Major sections are devoted to carbon, alloy, stainless and pressure vessel steels, as well as to superalloys. The effect of variables, such as grain size, cooling rate, stress intensity, and temperature are presented, along with numerous environments (e.g. calcium nitrate, dry nitrogen, mineral oil, sodium chloride, sodium hydroxide, wet air, fresh water, sea-water, etc.). Compiled from an exhaustive survey of the published literature, each curve has been carefully reviewed by A.J. McEvily, Jr. Professor, Department of Metallurgy, University of Connecticut. Dr. McEvily received the ASM Fellow citation for significant contributions to the understanding of fatigue crack initiation and growth in metals and alloys. Organized into a single, comprehensive source, this book is a valuable reference work for materials scientists concerned with stress corrosion cracking and corrosion fatigue.

TL;DR: In this paper, fatigue crack growth experiments have been carried out on a 2 1/4Cr-1Mo (ASTM A542, Class 2) steel in hydrogen, water vapor, and hydrogen sulfide at low pressures (below 133 kPa).
Abstract: Steels used in coal gasification vessels and piping (externals) can be exposed to mixtures of hydrogen, water vapor (steam), hydrogen sulfide, methane, carbon monoxide, carbon dioxide, and other gases at temperatures and pressures up to 600/sup 0/K and 10 MPa. Such mixtures, under certain operating conditions, can either enhance or inhibit crack growth in these steels. As a part of a program to identify thermodynamic conditions for this enhancement or inhibition, fatigue crack growth experiments have been carried out on a 2 1/4Cr-1Mo (ASTM A542, Class 2) steel in hydrogen, water vapor, and hydrogen sulfide at low pressures (below 133 kPa). The results indicate considerable enhancement of fatigue crack growth by some of these environments and also indicate that the apparent immunity of this material to stress corrosion cracking does not imply the same immunity to corrosion fatigue. The results will be discussed in terms of the influences of temperature, gas pressure and loading variables, and will be interpreted in terms of chemical reaction kinetics.

TL;DR: In this article, the influence of Cu and Mo additions on corrosion resistance of ferritic stainless steels in chloride media was investigated and it was shown that 0.5% Cu addition and the precipitation of e-Cu phases decreased the pitting corrosion resistance in a 19% Cr ferritic steels.
