Interaction of Metals and Gases

Abstract

MACMILLANEnglish edition © N. V. Philips ' Gloeilampenfabrieken, Eindhoven, 1971 Softcover reprint of the hardcover 1st edition 1971 978-0-333-07564-7 PREFACELike the first volume of 'Interaction of Metals and Gases' this second volume with the sub-title 'Kinetics and Mechanisms' handles the theoretical background as simply as possible. It has been written for metallurgical students, industrial metallurgists and chemists. Three subjects have been omitted from the book, those of adsorption, catalysis and oxidation, not because they are unimportant but rather because they are so all-important that a large number of excellent books are already devoted to them. Consequently this volume, with the exception of Section 4.12, deals exclusively with the behaviour of gases in the interior of metals, leaving interactions with metal surfaces out of consideration.

Hydrogen permeation through annealed zone-refined iron by using electrochemical charging at room temperature

“…Steels embrittled by hydrogen exhibit characteristic dependences on strain rate and temperature Similar de- (2) (3),(4),(5) pendences has been observed in both steels embrittled 1. in a bulk environment of molecular hydrogen and those by electrochemical charging, pickling, or prior exposure to·hydrogen at high temperature or perhaps pressuree At low strain rates, the absorbed hydrogen has a pronounced embrittling effect. If the strain rate is sufficiently large, the hydrogenated steel exhibits the same ductility as the unhydrogenated steel.…”

“…Qualitatively, the present work for specimen thickness greater than 0.13 cm agrees well with Oriani's ( 37) prediction(i.e. equation (2) in this thesis). However, for specimen thickness less than 0.13 cm, the opposite result is obtained.…”

Nitrieren von Eisen mit Ammoniak: Wachstum und Mikrostruktur der Nitride und Porenbildung in ζ-Fe2N

“…An der Phasengrenze a-Fe/c'-Fe 4 N gebildete Ko È rner von c'-Fe 4 N weisen nach TEM-Untersuchungen verschiedene uncharakteristische Orientierungsbeziehungen zum a-Fe auf [14]. Eine einkristalline c'-Fe 4 N-Schicht auf dem einkristallinen Eisengrundwerkstoff wurde an keiner Probe beobachtet.…”

Fuel Performance Evaluation for the Solid-Fueled Ramjet

“…MONITORING AGENCY NAME 6 ADDRESSfff different from Controlling OfUcm) Chief of Naval Research Arlington, VA 22217 15. SECURITY CLASS, ( The potential energetic performance of fuel ingredients for the use in the solid fuel ramjet is presented in terms of the enthalpy of combustion per unit mass and per unit volume of the fuel. Combustion phenomena and combustion efficiency are briefly discussed, but are not accounted for in evaluating the theoretical fuel performance.…”
