Abstract
In this study, Ce inoculated GX40CrNi25-20 material was produced by casting. The materials were subjected to heat treatment by being exposed to two different temperatures (1100, 1150 °C) and two different cooling intensities. The effects of heat treatment on primary and secondary carbide concentration, distribution, and type were investigated by using optical microscope, scanning electron microscope, energy dispersive spectrometry, X-ray diffraction, and microhardness tests. The adhesive wear behavior of the materials was determined. After the homogenization heat treatment, the increased cooling intensity application decreased the hardness of the samples. After the homogenization heat treatment, the size of the primary carbides decreased and their distribution became homogeneous. Secondary carbides were dispersed into smaller and equiaxed formin the matrix. EGR inoculating reduced the precipitation of carbides and changed the shape of the precipitate to granule.
期刊介绍:
Materials Testing is a SCI-listed English language journal dealing with all aspects of material and component testing with a special focus on transfer between laboratory research into industrial application. The journal provides first-hand information on non-destructive, destructive, optical, physical and chemical test procedures. It contains exclusive articles which are peer-reviewed applying respectively high international quality criterions.
