The Nitrocarburising Response of Low Temperature Bainite Steel

The Nitrocarburising Response of Low Temperature Bainite Steel

The nitrocarburising response of low transformation temperature ultrafine and nanoscale bainitic steel was investigated and compared with martensite and pearlite from the same steel composition. It was found that the retained austenite content of the bainitic steel dictated the core hardness after n...

The refined bainitic structure showed improvements in the nitriding depth and hardness of the nitrocarburised layer, compared to coarser grained martensitic and pearlitic structures, possibly due to the fine structure and the distribution of nitride forming elements.http://www.mdpi.com/2075-4701/7/7/234low temperature bainitenitrocarburisingsurface modificationretained austenitebainitic ferritetransmission electron microscopy
