2.2. Conventional carburizing procedure
For conventional carburizing, specimens from the as-received and
thermo-mechanically treated DSS were used. Prior to the process, the
specimens were ground using emery papers with a grit size ranging
from 240 to 1200 in order to remove the oxide layers and irregularities.
Following this, the specimens were cleaned using alcohol to
remove grease and other contaminants. The specimens were carburized
in a stainless steel container, as shown in Fig. 1a.
