Title : ( Magnetic nondestructive technology for detection of tempered martensite embrittlement )
Authors: Mehrdad Kashefi Torbati , Ali Rafsanjani , Saeid Kahrobaee , Moeen Alaei ,Abstract
A nondestructive eddy current technique is used to evaluate tempered martensite embrittlement in 4340 AISI steels after quench and tempering in the range 240–550 1C. A relation between the responses of the magnetic induction (normalized impedance of the coil) and destructive Charpy impact test results has been established. The study shows that the eddy current method could be used to separate brittle parts due to the microstructure changes.
