InvestigationI of Fatigue Properties Through Miniature Specimen Test Techniques
Original language description
One method for evaluating the mechanical properties of components in operation is the use of methods that focus on the use of miniaturized test specimens. Basic properties used mostly for the service life evaluation are tensile strength, impact notch toughness or impact notch toughness transition curve, fracture toughness, creep and high cycle fatigue. This research explores high cycle fatigue and tensile tests with the use of on standard test bars and sub sized samples obtained by semi destructive sampling. The first part of the testing was focused on the micro-tensile tests. The tensile tests were carried out to find out the initial stress level. In this research were studied the mechanical properties on steel X1 CrNiMoAlTi 12-11-2 and 16 343. The results from micro-tensile tests and high cycle properties show excellent agreement with each other. Therefore, this fact leads us to conclusion that the miniature specimen tests can replace the fatigue testing under certain circumstances. The use of miniature specimen brings many advantages such as cost reduction, non-invasive affection of the material, time saving
