Valencia Morales, EduardoSánchez Rijo, Yoel2018-01-302018-01-302012-06-20https://dspace.uclv.edu.cu/handle/123456789/8613Creep resistant welding alloys must be reliable over long periods of time in severe environments. Their microstructures have to be very stable, both in the wrought and in the welded states. This paper deals with quantitative methods for the design of steel weld metals for elevated temperature applications. A methodology is described for the calculation of complex precipitation reactions over periods extending many tens of years. However, microstructure alone is clearly not enough in the design of alloys. The complex mechanical properties, such as the creep rupture strength, can be estimated quantitatively using the neural network technique which interprets the vast quantities of experimental data that are now available.esEste documento es Propiedad Patrimonial de la Universidad Central “Marta Abreu” de Las Villas.
