M. Ahmed et al., MAGNETIC-PROPERTIES OF MARAGING-STEEL IN RELATION TO DEFORMATION AND STRUCTURAL PHASE-TRANSFORMATIONS, Acta metallurgica et materialia, 42(3), 1994, pp. 631-638
Magnetic properties in annealed and cold rolled conditions have been i
nvestigated for maraging steel grade 18%Ni-2400. The austenite content
, coercive field, saturation magnetisation and remanence were determin
ed after ageing for 1 h in the temperature range from 400 to 800-degre
es-C. The results show that the degree of deformation imparted to mart
ensite influences both the amount of reverted austenite and the magnet
ic properties obtained following ageing. Transmission electron microsc
opy was carried out in order to investigate the structural changes tak
ing place during reversion of austenite.
