An extensive program to characterize the microstructures and determine the mechanical properties of stainless steel welds is described. The amount, size, shape, and general distribution of ferrite in the weld metal was studied. The effects of electrode coatings on creep-rupture properties were determined as were the influences of slight differences in analyzed contents of carbon, silicon, phosphorus, sulfur, and boron. Using the above information, a superior commercially produced electrode was formulated which took advantage of chemical control over boron, titanium, and phosphorus. This electrode produced deposits exhibiting superior mechanical properties and it was successfully utilized to fabricate a large nuclear reactor vessel. (auth).

This book describes the fundamental metallurgical principles that control microstructure and properties of welded stainless steels. It also serves as a practical "how to" guide that allows engineers to select the proper alloys, filler metals, heat treatments, and welding conditions to insure that failures are avoided during fabrication and service.

T. H. NORTH Dept. of Metallurgy and Materials Science, University of Toronto. This volume documents the proceedings of the International Congress on Joining Research held under the auspices of the Canadian Council of the International Institute of Welding in Montreal, July 20/21 1990. This congress was sponsored by the Welding Institute of Canada, Oakville, Ontario. The study of joining is important, both from the fundamental and applied science points of view. Joining encompasses a wide range of areas, from welding processes, through welding metallurgy and materials science, to non-destructive testing, automation and field construction. Welding has sometimes been referred to as some curious combination of art and science. Certainly, from a university research perspective, the welding area is remarkably difficult to tackle because it is extremely difficult to sift out the critical variables. As a result, it is sometimes difficult to separate the real from the imaginary in any detailed evaluation of the joining literature. I sincerely hope that the authoritative contributions in this volume will sweep away any confusion that exists in the mind of the reader.

This work addressed two major areas concerning joining of advanced borated stainless steels. These areas included the development of a understanding of the physical metallurgy of borated stainless steels and the development of welding processes and post-weld heat treatments for these alloys. Differential thermal analysis experiments were conducted on ten heats of borated stainless steel to determine the transformation temperatures and melting behavior of the alloys. On-heating solidus temperatures were measured for all of the alloys and were used to define the temperatures associated with the fusion line during welding. Isothermal heat treatments designed to evaluate the effects of elevated temperature exposures on the toughness of the borated grades were conducted. These tests were used to determine if significant changes in the microstructure or mechanical properties of weld heat-affected zones (HAZ) occur. Specifically, the tests addressed the solid-state region of the HAZ. The test matrix included a variety of alloy compositions and thermal exposures at temperatures near the on-heating solidus (as determined by the DTA experiments). Welding experiments designed to assess the mechanical properties and microstructure of gas-tungsten arc and electron beam welds were conducted.
