METHOD FOR DETERMINING STRESS IN IRON-BASE FERROMAGNETIC MATERIALS Russian patent published in 1995 - IPC

Abstract RU 2035690 C1

FIELD: inspection of ferromagnetic materials for internal stresses. SUBSTANCE: material is subjected to multiple loading and minimum value of coercive force is recorded. This value is used as inspection result. EFFECT: improved validity of inspection due to measurement of coercive force when material specimen suffers strain. 3 dwg
