Book excerpt: High hardness steels (HHS) are vulnerable to hydrogen embrittlement, which can lead to rapid degradation of mechanical properties. Improved resistance to hydrogen embrittlement would be beneficial to many industries including construction, automotive, and military. A comparison study was performed to assess the hydrogen susceptibility of select commercially available and in-house designed HHS alloys. Slow strain rate tensile tests, performed with specimens charged with various levels of hydrogen, provided a macroscopic view of the onset of hydrogen embrittlement. Hydrogen permeation and thermal desorption spectroscopy tests determined the uptake and diffusivity of hydrogen through the material. The evaluation of hydrogen susceptibility for various HHS alloys provided a baseline for the design of an HHS alloy containing hydrogen embrittlement mitigation strategies. By incorporating strong hydrogen traps, titanium carbide and epsilon carbide, a HHS was produced that demonstrated a lower sensitivity to hydrogen embrittlement
Book Synopsis The Effects of High Pressure, High Temperature Hydrogen on Steel by : Ellis E. Fletcher
Download or read book The Effects of High Pressure, High Temperature Hydrogen on Steel written by Ellis E. Fletcher and published by . This book was released on 1964 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report deals with the deleterious effects of hydrogen gas on steel at elevated temperatures and/or pressures. Hydrogen attack on steels is manifest as decarburization, intergranular fissuring, or blistering. These conditions result in lowered tensile strength, ductility, and impact strength. The reaction of hydrogen with iron carbide to form methane is probably the most important chemical reaction involved in the attack on steel by hydrogen. Attack of steel at elevated temperatures and pressures is limited or prevented by the following measures: (1) use of steel alloyed with strong carbide-forming elements, (2) use of liners of resistant alloy steels, and (3) substitution of resistant nonferrous alloys.

Download or read book Designing Strength, Toughness, and Hydrogen Resistance written by Christopher David Kantner and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of the prototype evaluations were incorporated in the redesign of two new alloys, a higher toughness modification of the QSW alloy, and a higher strength modification targeting an ultimate tensile strength of 375 ksi while maintaining desired grain boundary compositions. The integration of quantum mechanical predictions with other computational design tools has proved effective in accelerating the development of high-performance alloys.

Book Synopsis Study of Effects of Alloying and Heat Treatment on Hydrogen Enbrittlement Susceptibility of Electroslag Remelted 4340 Steel by : Louis Raymond
Download or read book Study of Effects of Alloying and Heat Treatment on Hydrogen Enbrittlement Susceptibility of Electroslag Remelted 4340 Steel written by Louis Raymond and published by . This book was released on 1986 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: This program focuses on the need to improve the resistance of high-strength steels to hydrogen embrittlement of hydrogen stress cracking. Variations in heat treatment and modifications in alloy composition of electroslag remelted 4340 steel at 53 HRC were extensively explored. Target goals were established in terms of a threshold stress intensity parameter, KIscc for open circuit potential conditions, designated KIhem for cathodic charging conditions under stress during test, which were the primary test conditions in this program. In general, all alloy additions improved KIhem. The addition of 0.1% vanadium appears to be the most significant individual modification to ESR 4340 steel in that it alone provides the same gains as the more heavily alloyed ESR 4340 steels. The results must be somewhat qualified because the hardness of ESR 4340V was 50 HRC instead of the intended 53 HRC. Silicon additions of about 1.5% tended to maximize the benefits from alloy modifications. Although within an alloy system the heat treatment effects were monor or secondary relative to alloy additions, the use of an intermediate quench and subzero cooling appeared to maximize the benefits from heat treatment.
