“…In fact, a twinning structure only exists generally in <110> zone axis direction of FCC crystal and, nevertheless, has not been reported in <510> zone axis direction of M 23 C 6 , which could be related to its complex lattice structure. , which demonstrated M 23 C 6 4 had the same orientation relationship with M 23 C 6 3t and a twinning relationship with M 23 C 6 3 . The contact interface of two carbides was completely coherent on the grounds of atom arrangement on the growth frontier.…”

“…However, its wear resistance is usually low due to insufficient work hardening under nonstrong impact loads. Aging treatment is an effective method to improve wear resistance of high carbon high manganese steel while maintaining high toughness through carbide precipitation and pearlite transformation. − It is well-known that aging treatment is actually a desolution transformation process, where carbon is precipitated from supercooled austenite after a water toughening treatment to form carbides and even pearlite composed of carbide and ferrite with changing time and temperature. These metastable carbides, which maintain a coherent or semicoherent relationship with matrix, can be precipitated from austenite but not be coarsened as long as the heating temperature is not too high and the holding time is not too long during the aging process in order to realize dispersion strengthening through carbides dispersion at the interface.…”

Multiple interface structures of M23C6 carbides precipitated at grain boundary in 100Mn13 high carbon high manganese steel, including the interface between the carbide particle and the matrix together with the interface between two adjacent carbides, were studied after 1050 °C solution treatment and subsequently after 475 °C aging treatment by high resolution transmission electron microscope (HRTEM) based on traditional transmission electron microscope (TEM). A growth model describing the adjacent M23C6 precipitations was proposed. The results show that precipitated carbide type is M23C6, which grows into both sides of austenite by a step growth mechanism. When two adjacent carbides precipitate along grain boundary, there are two cases as follows: If the two carbides have the same orientation relationship with the same austenite grain, they would grow independently to contact with each other to coalesce into a larger size carbide with the same orientation relationship. If the two carbides have different orientation relationships with the same austenite grain, and there is an original twinning in one carbide, they would grow independently to contact with each other to form a precipitated twinning.

“…The microstructure obtained after aging process depend on the steel composition and the heat treatment parameters (i.e. time and temperature) [15,16]. The amount, morphology, number and distribution of carbides have a great impact on the steels mechanical properties and their service life [17].…”

Mechanical properties and microstructure evolution of high-manganese (0.9 C – 13.95 Mn) steel during aging

et al. 2021

The influence of temperature on the structural and mechanical properties of the (0.9 C - 13.95 Mn) steel was investigated in this work. The high-manganese steel has underwent aging treatments at temperatures 700, 750, 800 and 850 °C for different times. The experimental techniques used are hardness test, scanning electron microscopy, optical microscopy and X-ray diffraction. The mechanical behavior and microstructural evolution of the high-manganese steel during aging are almost the same. The aging of the high-manganese steel was characterized by a rapid hardening while the overaging by a slow softening. In aging, the dispersion of fine M7C3 carbides in the austenite led to an increase in hardness. In overaging, the softening was caused by the coarsening of the M7C3 carbides.
