Research of aluminum alloys with using eddy-current transducers on the basis of cores of various form

Abstract

Research of Steel to Dielectric TransitionAbstract. The research aims to develop a microminiature eddy current transducer for aluminum alloys. The research topic is considered relevant due to the need for evaluation and forecasting of safe operating life of aluminum. A microminiature transformer-type transducer was designed, which enables to perform local investigations of unferromagnetic materials using eddy-current method based on local studies conductivity. Having the designed transducer as a basis, a hardware-software complex was built to perform experimental studies of aluminium. Cores with different shapes were used in this work. Test results are reported for a flaws in the form of hidden slits and apertures inside the slabs is derived for excitation coil frequencies of 300-700 Hz.

Superminiature Eddy-Current Transducers for Studying Steel to Dielectric Junctions

“…For the purpose to measure the voltage of ECT at the dielectric-steel interface, a measuring system based on ECT [13,14] and a digital displacement transducer (DDT) were used. The ECT (Fig.…”

Control Quality of Composite Materials by Using Subminiature Eddy Current Transducers

“…Earlier, we reported on the successful development and testing of a virtualized measuring instrument -a conductivity meter for non-ferromagnetic materials -CMNFM-5FA [19,20].…”
