This book was released on 1962 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tensile, hot ductility, metallographic and weldability studies were conducted to determine the cause of base metal cracking in A-286 weldments. A mechanism for cracking was proposed, based on grain size, interstice formation by grain boundary sliding or Fe2Ti-Fe liquation, embrittlement by Ni3(Al, Ti) general and TiC grain boundary precipitation on insufficiently rapid cooling. The effect of stress on weld metal cracking was studied with variable restraint specimens, and optimum filler wires were evaluated on segmented finger specimens. The strain-age cracking study conducted on Rene' 41 and Inconel X concentrated on the non-equilibrium time between the annealed condition and the aged condition in the 1050 to 1500 F temperature range. Tensile and dilatometric studies indicated a possible transient embrittlement on initial heating. The time, temperature and prior material history dependence of the aging contraction was studied, and based on these results, and metallographic analysis of Inconel X, a mechanism to account for strain-age cracking was developed. The difficulties encountered in developing a valid strain-age cracking specimen are discussed. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Low melting filler wires, variations in base metal composition, and effects of prior material history were examined with respect to underbead cracking in A-286, with the latter being shown to be the controlling factor in cracking. Specimens were developed for evaluating strain age cracking propensity of different heats or different process treatments for sheet, bar, and plate material. Effects of long time-low temperature aging, pre heating, welding technique, peening, localized aging, and rate of heating on strain age cracking propensity were determined. (Author).
