The Magnetic Field

Hybrid-doped BaTiO3 ferroelectric ceramics Ba (Ti(0.99-x)Mn0.01Tax)O3 systems have been prepared by a conventional mixed-oxide method viavibro-milling technique. The dielectric properties at room temperature were observed under magnetic field applied parallel to electric field. The results indicate significant changes of both properties with the magnetic field. Moreover, explained in terms of the induction of magnetization by means of an electric field and induction of polarization according to domain switching of the dielectric properties under the influence of the applied magnetic field.

Proper Material

Knowledge of the properties and behavior of materials under certain working conditions is the basis for the selection of the proper material for the design of a new structure. This paper deals with experimental investigations of the mechanical properties of unalloyed high quality steel S235JRC + C (1.0122) and its behavior under conditions of high temperatures, creep and mechanical fatigue. The response of the material at high temperatures (20–700 °C) is shown in the form of engineering stress-strain diagrams while that at creep behavior (400–600 °C) is shown in the form of creep curves. Furthermore, based on uniaxial fully reversed mechanical fatigue tests (R=−1), a stress-life (S-N) fatigue diagram has been constructed and the fatigue (endurance) limit of the material is calculated The experimentally determined value of tensile strength at room temperature is 534 MPa. The calculated value of the fatigue limit, also at room temperature, using the modified staircase method and based on the mechanical fatigue tests data, is 202 MPa. With regard to creep resistance, steel 1.0122 can be considered creep-resistant only at a temperature of 400 °C and at an applied stress not exceeding 50% of the yield strength corresponding to this temperature.
