Abstract

ANALYSIS OF FINITE ELEMENTS OF THERMAL STRESS IN Fe-11Al alloy. The Finite Element Method-based ANSYS program has been used to analyze the thermal stress in vang alumina layers formed during high-temperature oxidation of Fe-11A1 alloy. The simulation model assumes the pure elastic behavior of the oxide layer as well as the ideal elastic-plastic behavior of its substrate metal. Studies on the stress relaxation effect by the deformation of substrate plastics and the effect of oxide geometry formed by flat-shaped oxides, convolutions, and porous convolutions have been carried out. The results of the calculation show that under certain temperature conditions. The tensile strength of the porous convolutional oxide reaches 678 MPa - 2 GPa and can exceed the tensile strength of σx of its alumina layer. The results of this voltage calculation are in accordance with the observations.
