Generally, material properties such as the modulus of elasticity, yield strength or fracture toughness are determined by conducting an experiment. Sometimes experimental determination cannot be done due to specific experimental conditions, lack of te

The structural changes of P91 steel after different heat treatment and M23C6 lattice expansion are well described by JMA kinetics law; however, the role of molybdenum on the M23C6 lattice expansion is not clearly revealed. The aim of the present work

Experimental test methods are used to determine material properties and fracture parameters. However, due to cost, lack of test material, etc., experimental tests cannot always be conducted. Therefore, there is a need for alternative methods to deter
