Notizen:
By controlled rolling and cooling process, a Mn-Ti high strength steel with yieldstrength on the order of 700MPa had been developed successfully. The microstructure consists offine lath shaped bainite and ferrite. The strengthening factors of this steel are attributed to the tinyinterlocked distribution of bainite lath and titanium carbide precipitation. When the amount ofbainite is more than 70%, the yield strength of steel is higher than 700MPa, and good mechanicalperformances are obtained. As a result of presence of finely dispersed bainite slabs the plasticityof steel is improved, with the steel’s elongation being about 19%. Many tiny TiC precipitates areobserved under transmission electron micrograph, and these particles result in precipitationstrengthening
