Effect of Pressure of the Corroding Liquid on the Strength of Metals During Low Cycle Fatigue Testing (Vliyanie Davleniya Zhidkoi Korrozionnoi Sredy na Prochnost Metallov pri Ispytanii ikh na Malotsiklovuyu Ustalost).

摘要

A negative effect of different corroding media, including water, on the strength of materials subjected to variable stresses has been known for some time. A large number of industrial equipment (pipes, reservoirs, tanks, etc.) are subjected simultaneously to variable stresses and high pressures produced by corroding liquid media. The performance of structural elements under these conditions is lowered, as well as their useful service life. This work was undertaken to study the effect of the water pressure (0-200 atm) on low cycle fatigue of cylindrical specimens (with a circular cut) made of different alloys.
