Abstract
Apparatus constructed in the Department of Metallurgy and Materials Science, University of Cambridge, has enabled the hot hardness of the individual steel phases, ferrite, austenite, cementite, pearlite, Type I MnS, Mn–MnS eutectic, and silicates to be measured in situ with a high degree of accuracy. The work was undertaken in the context of studies of the deformation behaviour of non-metallic inclusions in steel, where the relative yield behaviour of inclusions and matrix is clearly a significant factor. Because of their wider interest the hot hardness results are presented separately. The high-temperature hardness of pearlite, of significance in its behaviour in ‘warm’ working, has been explained in terms of the hardness of its constituent phases.
