Fioriti, I.Vasta, J.Starr, A.Mr. Fioriti is the Materials Engineer in the Hull Scientific and Research Section
Bureau of Ships with responsibility for materials and fabrication processes that are used in the construction of ship hulls. Mr. Fioriti attended the University of Pittsburgh receiving the Bachelor of Science degree in Metallurgical Engineering in 1951. He took postgraduate work at the University of Maryland receiving the Master of Science degree in 1960. From 1951 to 1956 he worked in the Metals and Metallurgy Section of the Bureau of Ships where he planned and administered research programs on metals for ships. He was associated intimately with the development of HY-80 steel and prepared the first specification used for its procurement by the Navy. In addition he was responsible for the development of dimpled armor plate for aircraft carrier flight decks. In 1956 he assumed his present position where he has been active in the Ship Structure Committee research program the low cycle fatigue structural program and the hydrofoil materials research program. Mr. Vasta is the Head of Hull Scientific and Research Section
Bureau of Ships with responsibility for planning initiating and technically monitoring research in the fields of structural mechanics and hydromechanics. Mr. Vasta attended New York University receiving the Bachelor of Science degree in Mechanical Engineering in 1930. He took postgraduate work at the Massachusetts Institute of Technology receiving the Master of Science degree in 1931. From 1931 to 1938 he worked at the United States Experimental Model Basin in the structural mechanics group. After a short duty at the Headquarters of the United States Coast Guard he joined in 1939 the staff of the United States Maritime Commission where he held various positions of responsibility in the Technical Division. He was associated intimately with the design development of the reinforced concrete ship program first as Assistant Chief and then as the Chief of the Section. Thereafter he was appointed Assistant Chief of

Research program of U S Bureau of Ships is in final phase;literature survey and screening phases are completed;on basis of tests, fabrication studies and cost analyses most promising materials are steels 4330M and 17-4PH (H1025) with protective coatings, and 2 titanium alloys (8AL-2CB-1TA) and (6AL-4V);most promising coatings are polyurethane rubber and neoprene rubber base coatings;coated HY-100 steel is satisfactory for low performance foils;glass laminates are of particular interest as foil materials and are under study;no "off shelf" material is ideal for high speed foils.
