LOW-CYCLE FATIGUE OF NONFERROUS ALLOYS FOR HEAT EXCHANGERS AND SALTWATER PIPING

Abstract

The fourth phase of an investigation of the low-cycle fatigue behavior of nonferrous alloys for submarine heat exchanger and saltwater piping applications is reported. The low-cycle fatigue behavior of forged Ni-Al bronze and cast valve bronze was investigated in both air and salt water. The flexural fatigue behavior of these two materials, together with cast Ni-Al bronze and cast Monel 'E' of phase three, were compared to that predicted by Langer's equation. It was concluded that Langer's equation was overly conservative for the materials reported, and that saltwater corrosion has very little effect on low-cycle fatigue life. Both cast and forged Ni-Al bronze rank as superior, whereas valve bronze ranks poorly as far as low-cycle fatigue performance is concerned.
