Notes:
This work explores the effect of Cr addition on the kinetics of strain ageing process. Thestrain ageing behaviour of low carbon steel with and without 0.7wt% Cr was investigated usingtransmission electron microscopy (TEM), atom probe tomography (APT) and tensile tests. Theresults have shown that Cr alloyed steel undergoes the same three stages of ageing as unalloyed lowcarbon steel. However, the alloying with Cr reduces the rate of strain ageing by ~2 times incomparison with non-alloyed low carbon steel. It especially delays the offset of stage III. This isexplained by the reduction of carbon content in ferrite due to the enrichment of cementite with Crleading to the reduction of its equilibrium solubility in ferrite
