... that the fracturing had something to do with the precipitation of sigma phase. Metallographic examination showed that the multiaxial stresses caused by sigma phase formation and the related embrittlement was the cause for the fracture of the recuperator. A steel of lower chromium content with no or little tendency...

Cyclic strain accumulation, or ratcheting, requires that a part be stressed by steady-state loading, either uniaxial or multiaxial, and that a cyclically varying strain in a direction other than the direction of principal stress be superimposed on the part. In ratcheting, an oscillating load or a cyclic...
