NON DESTRUCTIVE DETERMINATION OF STRESSES IN STEELS BY ULTRASONIC AND MAGNETIC METHOD.

Objective

THIS PROJECT IS A FOLLOW-UP TO TWO EARLIER CONTRACTS (7210.GA/120 AND 7210.GA/810) IN THE SAME FIELD. THE AIM IS TO DEVELOP A MEASURING METHOD TO DETERMINE INTERNAL MECHANICAL STRESSES IN ROLLED AND FORGED PRODUCTS.
INTERNAL STRESSES, WHICH WILL BE ANALYSED SOLELY BY AN ULTRASONIC METHOD USING TRANSVERSE WAVES OF DIFFERENT POLARITY, WILL BE DISTINGUISHED FROM SURFACE STRESSES AND STRESS GRADIENTS, FOR WHICH MAGNETIC METHODS WILL BE USED (DYNAMIC MAGNETOSTRICTION, BERKHAUSEN EFFECT, ETC.) BECAUSE OF THEIR GREATER SENSITIVITY. THE DEVELOPMENT OF THE ULTRASONIC METHODS WILL CONSIST OF IMPROVING THE TRANSVERSE WAVE EMITTORS AND RECEIVERS AND THE PROCESSING ELECTRONICS.

THE MAGNETIC METHODS WILL BE ADAPTED AND IMPROVED AND PROTOTYPES WILL BE CONSTRUCTED.

THE PROGRAMME WILL ALSO INCLUDE BASIC RESEARCH TO IDENTIFY THE EFFECTS OF THE STRUCTURE AND OF THE STRESSES STEMMING FROM THE INFLUENCE OF THE STEEL STRUCTURE ON THE MEASUREMENTS PROPER.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.
