Martensite formed in plain carbon steels containing less than 1·4% carbon has been studied by direct examination of thin foils in the electron microscope. It was found that the martensite in low-carbon steels forms predominantly as long needles parallel to <111>M while in the high-carbon steels it forms as plates internally twinned on a fine scale. The existence of these narrow twins in the high-carbon martensites enables the transformation mechanism to be derived uniquely. This mechanism… 
Particularities of the formations of bainite and martensite/austenite phase in low carbon low alloy steels during continuous cooling
Abstract The industrial X80 steel chemistry has been modified by increased amounts of Mn, Cr and a new leaner base chemistry (0Ni-0Cu-0.04Nb) has been used with carbon contents of ± 0.04 and 0.07

The Bainite Reaction in Fe-Si-C Alloys: The Secondary Stage
The de composition of austenite following the initial rapid formation of bainitic ferrite in silicon alloyed high-carbon steels isothermally transformed at 380 °C has been studied. The reaction is
A new nanoscale metastable iron phase in carbon steels
An intensive TEM investigation revealed that extra diffraction spots observed by transmission electron microscopy are in fact attributed to the metastable ω phase in particle-like morphology with an overall size of several or dozens of nanometres.
A Mössbauer study of the surface martensite in 1095 steel
The extent of the martensitic transformation on the surface was measured with reference to the bulk value in a quenched 1095 steel using the Mössbauer effect scattering technique. The difference
The morphology of martensite in iron alloys
Light and electron microscopy have been used to determine the main structural differences between the two major types of martensite in ferrous alloys. In the martensite that forms in dilute alloys of
