LASER STAMPING OF AMORPHOUS ALLOYS USED IN MOTORS, TRANSFORMERS & SECURITY SYSTEMS

THE NEWLY DISCOVERED AMORPHOUS ALLOYS HAVING UNIQUE MECHANI-CAL AND ELECTROMAGNETIC PROPERTIES ARE BECOMING AVAILABLE INVERY THIN AND NARROW STRIPS WHICH DO NOT LEND THEMSELVES TO CONVENIENT AND EFFICIENT METHODS OF MANUFACTURING. IT ISNECESSARY TO PROCESS THESE ALLOYS FOR NEW APPLICATIONS IN WAYS WHICH PRESERVE THEIR UNIQUE CHARACTERISTICS YET PROVIDEMANAGEABLE SIZES AND SHAPE FOR INCORPORATION INTO ELECTRICALMOTORS, TRANSFORMERS REMOVAL AND OTHER DEVICES. THIS PROPOSAL SELECTS LASER MACHINING AND WELDING OF AMORPHOUS ALLOYS AS A TECHNOLOGICAL SOLUTION WORTHY OF DETAILED RESEARCHAND DEVELOPMENT. SPECIFIC OBJECTIVES INCLUDE STUDIES OF LASER-SOLID INTERACTIONS, MEASUREMENTS OF MATERIAL REMOVAL RATES, ESTABLISHMENT OF PARTICULAR GEOMETRICAL CONDITIONS FOR CUTTING AND WELDING OF TOROIDAL CORE LAMINATIONS, EVALUATION OF ALLOY PROPERTIES BEFORE AND AFTER LASER PROCESSING AND REFINEMENT OF OPERATING PARAMETERS TO THE POINT WHERE VALID CONCLUSIONS CAN BE REACHED. THE RESEARCH CAN LEAD TO AMUCH GREATER USE OF AMORPHOUS ALLOYS IN A VARIETY OF APPLICATIONS WITH ENORMOUS SAVINGS IN COST OF ENERGY AS USAGE IN- CREASES. A DIRECT APPLICATION CAN BE THE INTRODUCTION IN PHASE II OF A PROTOTYPE SYSTEM FOR SPECIAL APPLICATIONS OF AMORPHOUS ALLOYS IN GEOMETRIES NOT READILY AVAILABLE FROM THE PRODUCERS OF ALLOY RIBBON.
