Microstructural evolution during tempering of a multiphase steel containing retained austenite

Study of the decomposition behavior of retained austenite and the partitioning of alloying elements during tempering in CMnSiAl TRIP steels

“…4(b). As mentioned previously [26], the type of dislocation is caused by a loss of coherency across the interface during RA decomposition.…”

Subgrain lath martensite mechanics: A numerical–experimental analysis

“…Their presence has been reported in various low carbon steels (Bhadeshia, 1979;Law and Edmonds, 1980;Kim and Thomas, 1981;Rao and Sachdev, 1982;Samuel, 1985;Lee and Su, 1999;Nakagawa and Miyazaki, 1999;Jha and Mishra, 1999;Morito et al, 2011;Baltazar Hernandez et al, 2011;Kim et al, 2012;Nayak et al, 2012;Song et al, 2012). Austenite can be retained at room temperature because of either chemical or mechanical stabilisation.…”

“…Their presence has been detected with TEM in lath martensite in a number of low carbon steels, e.g. martensitic (Law and Edmonds, 1980;Samuel, 1985;Morito et al, 2011), also tempered (Lee and Su, 1999), stainless steels (Nakagawa and Miyazaki, 1999), DP steels (Kim and Thomas, 1981;Rao and Sachdev, 1982;Jha and Mishra, 1999;Baltazar Hernandez et al, 2011;Kim et al, 2012), low alloyed TRIP steels (Nayak et al, 2012;Song et al, 2012).…”

Microstructure evolution of hot-work tool steels during tempering and definition of a kinetic law based on hardness measurements

“…In other respects, relations between time, temperature and composition with the microstructure obtained after tempering have also been intensively investigated [7][8][9][10][11][12][13][14][15]. Without any doubt, the famous work of Hollomon and Jaffe has led to the most well known relation.…”
