Сталь. 2015. № 9. С. 36–41.
Hot forming behavior of high-strength automotive steel HC420LA is the main objective of this work. Uniaxial and plane strain compression tests were performed at Gleeble 3800 testing machine. A comparison of these types of tests was realized. The material constitutive constants were found as well as the dependences of peak and stady-state stresses on strain rate and temperature. It is shown that the testing technique have an impact on the stress-strain curves obtained by its implementation, this can lead to a mismatch of results of computer simulation of metal forming technologies. In order to evaluate such mismatches a finite element simulation of bar rolling process using the material properties obtained by different testing methods is considered.

We perform a Monte Carlo analysis of the Ising model on many three-dimensional lattices. By means of finite-size scaling we obtain the critical points and determine the scaling dimensions. As expected, the critical exponents agree with the three-dimensional Ising universality class for all models. The irrelevant field, as revealed by the correction-to-scaling amplitudes, appears to ...

Uniaxial tensile testing of flat specimens under superplastic conditions is widely used to determine the deformation behavior of materials. However, the standard interpretation of the results relies on the hypothesis of an ideal uniaxial stress state and often fails to account for the influence of specimen geometry and material flow from the gripping zones to ...
