Abstract:

A new method of testing metals for creep and stress relaxation, which requires no complex equipment and makes such tests possible en masse, was developed. The basis of the method is a specimen possessing low rigidity whose working part is a cylindrical spring of square cross-section. This type of specimen eliminates expensive equipment and substantially increases accuracy in the measurement of creep deformation. The proposed method is the first to permit organization of mass tests of the creep resistivity of boiler pipes of any geometry, including those for steam superheaters, screening equipment, and heat-exchanging apparatus.
