Issue Date: | Jul-2004 | Publisher: | Institute of Materials, Minerals and Mining | Citation: | Materials Science and Technology 20(7): 814-818 (2004) | Abstract: | Recent work has shown that bainitic ferrite plates produced by transformation at low temperatures can be as thin as 20 nm with a hardness in excess of 650 HV30, tensile strength 2.3 GPa and toughness 30 MPa m1/2. Because these properties rely on the fine scale of the microstructure, a study has been carried out in relation to the tempering resistance of steel over the temperature range 350–750ºC. It is found that significant softening occurs only after the plates of ferrite begin to coarsen. The coarsening process is hindered by the intense precipitation of carbides resulting from decomposition of the carbon enriched retained austenite. The carbides themselves lead to some precipitation strengthening during the early stages of tempering. The ferrite is found to contain excess carbon, beyond its solubility limit, and X-ray analysis indicates that the carbon is associated with heterogeneous strains in the microstructure. It does not readily precipitate until the onset of substantial recovery during annealing. | Description: | 5 pages, 6 figures, 2 tables. | Publisher version (URL): | http://dx.doi.org/10.1179/026708304225017355 | URI: | http://hdl.handle.net/10261/3183 | DOI: | 10.1179/026708304225017355 |
