The Metal Magnetic Memory (MMM) and Practical Application
G. Sofronić
Sažetak
The method was appeared as result of constant client’s demands to make a testing in very short time, making a tested object useful so soon to reduce the stoppage time and costs. Using the measuring of own magnetism and physical phenomenon of magnetostriction on very fast and precise way the areas of stress concentration will be uncovered, which in second phase become the object of other NDT methods application. In work paper was shown a testing application of: vessel - dimensions Ø 5000 x 6 mm, welds of gas line and central (axial) hole of middle pressure (MP) and high pressure (HP) turbine rotor. The testing was done by measurer of stress concentration IKN-3M-12.
