Numerical simulation of the mechanical behaviour of ultrafine - and coarse - grained Zr-Nb alloys over s wide range of strain rates
This paper presents the results on the development of theoretical methods of evaluation and prediction of mechanical properties of Zr–Nb alloys over a range of strain rates from 10−3 to 103 s−1. The mechanical behavior of coarse- and ultrafine-grained Zr–1Nb (E110) was investigated numerically. The ranges of strain rates and temperatures in which the mechanical behavior of Zr–1Nb alloy can be described using modified models of Johnson–Cook and Zerilli–Armstrong were defined. The results can be used in engineering analysis of designed technical systems for nuclear reactors
Damage of high-chromium steels under deformation in a wide temperature range
High-chromium steels have high strength properties, corrosion properties and resistance to neutron irradiation, thereby are considered as promising steels for nuclear reactors of generation IV. The deformation and damage of high chromium steels in a wide temperature range was studied by numerical simulation method. A model was proposed to predict the deformation and damage of high chromium steels under quasi–static loading within the temperature range from 295 to 1100 K. It is shown that the ductility of high-chromium steels increases proportionally to temperature in the range from 750 to 1100 K due to the growth of α′-phase precipitates
