a native of Baltimore graduated in 1969 from Drexel Institute of Technology with a Degree in Metallurgical Engineering. While attending Drexel he worked as a co-op student at NSRDL in Annapolis Md. where he developed a special interest in stress-corrosion cracking of titanium alloys. Upon graduation he joined the Naval Ship Engineering Center as a Materials Engineer. He is a member of the Association of Senior Engineers the American Society for Metals the American Institute of Mining Metallurgical and Petroleum Engineers and the Alpha Sigma Mu Metallurgy Honorary Fraternity. David E. Smith was born in Brooklyn
and attended Rensselaer Polytechnic Institute where he graduated in 1959 with a Degree in Metallurgical Engineering. After spending three years as a communications officer for the Air Force he joined the Dow Chemical Company as a Welding Engineer. After two and a half years he then worked for Ling-Tempco-Vought prior to joining the Naval Ship Engineering Center as a Materials Engineer in 1967. One of his most important projects has been the Structural Titanium Alloy Development Program which he has monitored over the lost three years. He is a member of the American Society for Metals the American Welding Society and the Association of Senior Engineers.

Titanium, “the wonder metal of the future” is rapidly becoming the metal of the seventies. The high strength to weight ratio, the excellent corrosion resistance in many aggressive environments, and good elevated temperature properties have resulted in the widespread use of titanium and its alloys, particularly in the aerospace and chemical industries. Titanium has demonstrated its superiority in sea water environments, yet the marine industry has been slow to utilize titanium's benefits. The intent of this paper is twofold—First to inform the marine industry on many advantages of titanium alloys for sea water use by describing properties and successful applications. Second, to show how susceptibility to stress corrosion cracking of certain titanium alloys, which became evident several years ago, is now understood and controllable. Well documented research has substituted knowledge for doubt and fear. Titanium and several titanium alloys are considered ready for use as engineeringmaterials in the marine industry. Today, they are competitive with nickel base alloys in cost. Naval architects and design engineers may now use titanium in certain applications to provide superior performance over traditional marine materials.
