Abstract
The effects of titanium and post-rolling treatments on the low cycle fatigue properties of weathering high strength low alloy steels were investigated. The post-controlled-rolling treatments were air colling, water spraying and normalizing. All the steels cyclically hardened, but the amounts of cyclic hardening varied with the post-rolling treatment. Water spraying produced initial cyclic hardening and softening, whereas air cooling or normalizing yielded cyclic hardening modes. The water-sprayed condition exhibited a better strain-life fatigue resistance than that of the air-cooled condition. Normalized titanium-bearing steel displayed the best strain-life fatigue resistance. The fatigue resistance was increased by adding titanium, compared with that of titanium-free steel. At 2.0% total strain the fatigue life was doubled by alloying with 0.1 wt.% Ti.
