The purpose of this discussion is to assess the state of our understanding concerning the factors and mechanism(s) which determine and control the susceptibility to stress-corrosion cracking of the austenitic stainless steels. The growing importance of this problem has led to a considerable amount of research, both in this country and abroad, aimed at delineating more specifically the environmental, compositional, and structural conditions involved and at elucidating the underlying mechanism for the cracking phenomenon. As a result of this research effort, a number of mechanisms have been proposed, but all appear to contain certain deficiencies in explaining certain of the characteristic features of the stress-corrosion cracking process; that is to say, unequivocal arguments cannot be presented in behalf of any of the proposed mechanisms. Possibly more to the point is the fact that few of the currently debated mechanisms have yielded critical clues which could lead to compositional or structural modifications of commercial materials to reduce or prevent the incidence of cracking. It is encouraging to note, however, that the more recent experimental evidence is developing a basis whereby critical type of experiments can be designed to differentiate clearly the mode of damage.
FOREWORDThis report of the "Symposium on Titanium" is a complete record of the formal talks that were presented at the meeting called by the Office of Naval Research on 16 December 1948. The purpose of this meeting was to bring together those government agencies and industrial organizations actively engaged in the research and development of titanium and its alloys so as to provide, for the first time, a comprehensive review of the titanium research effort and the progress thus far attained.Titanium and its alloys represent a potentially important metal system which is currently receiving much interest and attention. The Navy has a vital stake in the development of light, strong and corrosion-resistant metals and looks forward to the full exploitation and development of this most promising metal system. It is hoped that this report will be of value to those working in the field of titanium and to all potential consumers of titanium and titanium alloys. To all those who took an active part in the symposium, the Office of Naval Research expresses its appreciation. T. A.

It gives me great pleasure to welcome you to this Symposium. Admiral Solberg is unable to be present because he has been called to a meeting of the Naval Research Advisory Committee in New York and he asked me to express his regrets. This is one of a series of Office of Naval Research Symposia on metals aimed at presenting and discussing recent trends in metallurgical research and development. The Navy is particularly interested in titanium because of its promise as a suitable structural material. Its high strength-weight ratio, its corrosion resistant properties, and its high temperature characteristics are all very attractive. Its natural abundance in the United States is also an important reason for giving it careful consideration.During the past war the Navy, and American industry worked together as a team to build up the greatest naval force in all history. It was a remarkable job which required the closest kind of cooperation, and it clearly indicated how much can be accomplished under the American system when we all put our shoulders to the wheel. Even though the war is over and won, it is still important that we work closely together. For this reason the Office of Naval Research particularly welcomes this meeting. It provides the opportunity for a review and discussion of the titanium programs under way and should stimulate and encourage the application and utilization of this new metal. Titanium shows great promise. It is up to industry and the military services working together to solve the many problems that face us before titanium can be used in quantity. The successful solution of the problem will provide good insurance for the future. With the announcement of the small-sca...
