Abstract :
Tempering of the engineering steel AISI/SAE 4340 in the temperature range 250-600degC for 1 hour and 10 hours was studied. 3D atom probe techniques were used to map the redistribution of all major alloying elements (Si, Cr, Mn, Ni and Mo) between ferrite and carbide phases as a function of temperature and time. Field emission ion microscopy image shows dislocation spiral and grain boundary in the samples studied
