CONCERTED EUROPEAN ACTION ON MAGNETS II

Objective

CEAM II operates on the basis of a series of general and topical meetings. There is a quarterly newsletter, and an information service and database operated from the Laboratoire Louis Neel, Grenoble. By bringing together most of the European manufacturers and uses of rare- earth iron permanent magnets, along with the academic research groups specializing in this branch of magnetism in a unique collaborative effort, it has proved possible to strengthen significantly the capabilities of European players in this field.

A COORDINATED ACTIVITY ON RARE EARTH IRON PERMANENT MAGNETS AND THEIR APPLICATIONS IS PROPOSED. IT IS INTENDED TO BUILD ON THE ACHIEVEMENTS OF THE CONCERTED EUROPEAN ACTION ON MAGNETS (CEAM) WHICH RAN FROM 1ST OCTOBER 1985 TO 30TH SEPTEMBER 1988 AND WHICH LED TO THE ESTABLISHMENT OF STRONG LINKS BETWEEN RESEARCH ON ADVANCED MAGNETS AND THEIR INDUSTRIAL APPLICATIONS.

THE PRINCIPAL AIM OF CEAM II IS A COORDINATED RESEARCH EFFORT ON THE PHYSICAL PROPERTIES, FABRICATION AND APPLICATION OF ADVANCED RARE-EARTH IRON PERMANENT MAGNETS WITHIN THE EUROPEAN COMMUNITY. APPROXIMATELY SIXTY ACADEMIC AND INDUSTRIAL LABORATORIES ARE TO BE INVOLVED IN THE PROGRAMME.

THE TOPICS OF RESEARCH AND DEVELOPMENT ARE TO BE FOLLOWING:
- SYNTHESIS OF NEW INTERMETALLIC COMPOUNDS AND DUPLEX ALLOYS OF POTENTIAL INTEREST AS PERMANENT MAGNETS.

- INTRINSIC MAGNETIC PROPERTIES OF THESE NEW COMPOUNDS, AND SPECIFIC IMPROVEMENTS CONCERNING THE R2T14B SERIES.

- MECHANISMS FOR THE DEVELOPMENT OF COERCIVITY AND HYSTERISIS

- METALLURGICAL MICROSTRUCTURE AND PHASE RELATIONS

- STABILITY AND CORROSION STUDIES

- IMPROVEMENT OF THE PROCESSING OF RARE-EARTH IRON MAGNETS BY THE POWDER METALLURGY ROUTE.

- DIRECT PROCESSING ROUTES SUCH AS HOT WORKING OF INGOT OR DIRECT CASTING.

- BONDED MAGNETS WITH BOTH ORGANIC AND SOFT METAL MATRICES.

- APPLICATION OF BONDED MAGNETS IN REDESIGNED SUBFRACTIONS HORSE POWER MOTORS.

- IMPROVED INDUSTRIAL MACHINES FOR USE AT ELEVATED TEMPERATURES.

- DETAILED INVESTIGATION OF ASSEMBLY AND MAGNETIZATION STRATEGIES.

- EXPLOITATION OF HIGH-PERFORMANCE ND-FE-B MAGNETS FOR HIGH TORQUE-DRIVES, STEPPER MOTORS, BRUSHLESS D C MOTORS, SYNCHRONOUS MOTORS AND ACTUATORS.

- STATIC APPLICATIONS OF HIGH-PERFORMANCE MAGNETS.

- HIGH-ENERGY PERMANENT MAGNETS IN MEDICAL APPLICATIONS
