- In the present study, microstructural changes of sintered steel under compressive load are studied by a novel method. The aim is to gain further understanding of how the pores and microstructure react to different loads, which is of interest for surface densification of PM steels. Images of polished cross-sections are acquired before and after Brinell-indentation. Distinct features of the before and after images are matched using image registration, revealing the microstructural changes underneath the surface of the PM steel due to plastic deformation by the indentation. The method is reliable and provides accurate measurement of microstructural changes providing data that will broaden the understanding of how the microstructure is altered at loads above the yield limit.
