Abstract : Contents: stress-corrosion cracking of titanium alloys in salt water, fresh water, and sea water; stress-corrosion cracking tests on welded titanium alloy plates; a new stress-corrosion cracking test procedure for high strength alloys; a study of the stress factor in corrosion cracking by use of the pre-cracked cantilever beam specimen; a study of the crystallographic orientation of cleavage facets produced by stress-corrosion cracking of Ti-7Al-2Cb-1Ta in distilled water; the effectiveness of sodium chromate to inhibit stress-corrosion crack propagation in aisi 4340 steel; metallic corrosion and cathodic protection to 5652 foot ocean depths; performance of tributyl tin oxide and cuprous oxide antifouling paints on 5086-H32 and 6061-T6 aluminum alloys in sea water and river water exposures; status report on the current distribution along a wire rope cathode; inoperative galvanic anodes related to improper chemical composition of the zinc; determination of the effective driving potential and effective d.c. resistance of galvanic anodes; low cycle fatigue crack propagation in 'wet environments'.
