Available in PDF, EPUB and Kindle. Book excerpt: Slow strain rate methods are used to quantify the degree of embrittlement in high-strength 4340 steel after coating with porous electroplated cadmium or ion-vapor-deposited aluminum and subsequently exposing to aqueous sodium chloride environments for various times. Porosity in the coatings is primarily responsible for the establishment of galvanic couples at the steel/coating interface, resulting in the generation and absorption of hydrogen in the steel. Data from hydrogen permeation and galvanic corrosion experiments are used to establish a model for hydrogen generation in coated tensile specimens. Estimates of the total hydrogen absorbed in cadmium-plated tensile specimens are consistent with the results of slow strain rate tests whereas similar calculations grossly underestimate the total hydrogen absorbed in aluminum-coated specimens where localized corrosion processes are believed to enhance the rate of hydrogen generation.

Book Synopsis Assessment of the Degree of Hydrogen Embrittlement Produced in High-Strength 4340 Steel by Plating-and-Baking Processes Using Slow Strain Rate Testing by : William J. Pollock
Download or read book Assessment of the Degree of Hydrogen Embrittlement Produced in High-Strength 4340 Steel by Plating-and-Baking Processes Using Slow Strain Rate Testing written by William J. Pollock and published by . This book was released on 1988 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The degree of hydrogen embrittlement produced in high-strength 4340 steel by various cadmium, cadmium-titanium, and nickel plating-and-baking procedures is assessed from fracture stress values obtained during slow strain rate tests using notched tension specimens. At low crosshead displacement rates, the slow strain rate method is capable of quantifying the degree of embrittlement produced by a variety of low-embrittlement, plating-and-baking procedures and is more sensitive than conventional test methods defined in standard specifications. The advantages of using a slow strain rate method as a viable alternative to existing standard methods for assessment of the degree of hydrogen embrittlement in plated-and-baked, high-strength steel are discussed.

This book was released on 1988 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present work demonstrates how a slow strain rate test can be used to quantify rapidly the severity of hydrogen embrittlement produced in porous cadmium plated-and-baked high-strength 4340 steel by paint strippers. The results of multiple slow strain rate tests, conducted at a crosshead displacement rate of 2 x 10-4 mm/s using notched tension specimens in various paint strippers, show that a minimum mean fracture stress within the range of 1700 to 1850 MN/m2 can be correlated with the pass/fail criterion for acceptability of paint strippers in standard notched C-ring tests. The advantages of using a slow strain rate test as a viable alternative to existing standard methods for hydrogen embrittlement testing are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: The use of high strength steels, free of hydrogen embrittlement, gave rise to an investigation into the effect of hydrogen and the methods of preventing or eliminating embrittlement. Hydrogen, induced by cathodic charging, cyanide and fluoborate Cadmium plating, and Chromium plating, was shown to produce embrittlement which varied in severity with the strength level and charging technique in SAE 4340 and 4140 steels. These steels were heat treated to the tensile strength level range between 180,000 and 270,000 psi. The susceptibility to embrittlement increased with increasing tensile strength. Fluoborate Cadmium plating did not embrittle as much as other charging methods tested. Minimum baking treatments to relieve embrittlement were determined for each strength level and charging technique. Static fatigue limits were determined for SAE 4140 steel electroplated with Cadmium and Chromium. The use of Cadmium and electroless Ni preplates as barriers to hydrogen diffusion was proven unsatisfactory as a method of preventing hydrogen embrittlement. An H-11 type tool steel, plated with Ni and Cadmium and baked at 600 F, produced an unembrittled corrosion protected steel.
