Effect of microstructure on elastic property at high temperatures in ferritic heat resistant steels

Parametric study of irradiation effects on the ductile damage and flow stress behavior in ferritic-martensitic steels

“…(4) are obtained by performing a least square fit of the true stress-strain curve till ultimate tensile stress and are given in Table 2. The same Young's modulus (E) and Poisson's ratio (n) values are utilized for both the materials [34,35] as shown in Tables 2 and 4, and are not varied with irradiation dose-levels. A parametric study is then performed to determine the ductile damage parameters of the unirradiated specimen and the values of the parameters appearing in Eqs.…”

A radiation hardening model of 9%Cr–martensitic steels including dpa and helium

“…However, such a normalization based only on the slope of the Young's modulus is not enough, in particular in the high temperature range. Indeed, it was experimentally found that the Young's modulus variation with test temperature measured with an ultrasonic method exhibits a lower slope than when measured with tensile tests [6], the disagreement increasing with test temperature (see Fig. 1).…”

Dynamic Recrystallization and Dynamic Precipitation Behaviors of a 17Ni–0.2C Martensite Steel Studied by In Situ Neutron Diffraction

“…Here the high-temperature Young's modulus E is taken as 185 GPa. 30) That is to say, the (hkl) peak shifts of austenite related to the lattice strain are mostly due to the external stress.…”
