Corrosion-mechanical strength of structural materials in contact with liquid lead

Corrosion-mechanical tests of 10Kh15N9S3B and 10Kh9NSMFB steel samples in liquid lead at 360-550C have shown that the long-time strength in lead flow decreases at short times to fracture and converges to the results of tests performed in air at about 10000 h. No liquid-metal embrittlement of 10Kh15N...

Zusammenfassung:	Corrosion-mechanical tests of 10Kh15N9S3B and 10Kh9NSMFB steel samples in liquid lead at 360-550C have shown that the long-time strength in lead flow decreases at short times to fracture and converges to the results of tests performed in air at about 10000 h. No liquid-metal embrittlement of 10Kh15N9C3B steel is observed. 10Kh9NSMFB steel becomes brittle in the hardened state. Embrittlement intensifies in notched samples. The low-cycle fatigue strength is correlated with a change in ductility with short-time fracture. No decrease of fracture toughness of 10Kh9NSMFB steel with a fatigue crack was observed in tests in liquid lead.
