Abstract:
Mn18Cr2 steel is one of austenitic deformation strengthening steel. The existing form of TiN and its influence on the austenitic structure in the steel by adding small amounts of TiN nanoparticles are discussed in this study, which may provide some advices to explore new way to strengthen high manganese steel. The microstructures of Mn18Cr2 steel added small amounts of TiN nanoparticles are observed by Transmission Electron Microscopy (TEM). The results show that TiN nanoparticles exist in austenite and there have a very good match interface between the two phases, the crystal face relationship are {220} γ //{220} N , {422} γ //{422} N , (111) γ //(200) N , orientation relationship are 〈 110 〉 γ // 〈 110 〉 N , 〈 211 〉 γ // 〈 211 〉 N , [112] γ // [011] N , moreover, the relationship of (111) γ and (200) N is not only parallel but also coherent. Meanwhile, there are many high density dislocations, a small amount of stacking faults, twins and ε-martensite in the austenite due to the role of TiN nanoparticles.
