Microstructural, thermal and magnetic properties of amorphous/nanocrystalline FeCrMnN alloys prepared by mechanical alloying and subsequent heat treatment

Crystal interstitial sites contribution to nitrogen supersaturation in mechanically alloyed Fe–Cr–Mn–N alloys

“…Moreover, nitrogen intensifies the structural refinement, aiding amorphization. On the other hand, nitrogen in the Fe-Cr-Mn-N alloys increases the atomic size mismatch and negative heat of mixing among the constituent elements [14][15][16][17][18], encouraging amorphization significantly according to the Inoue's empirical rules [31].…”

“…Nitrogen alloying via MA can be accomplished by either milling under a nitrogen atmosphere or milling with proper nitrides under an inert gas. The generation of the high density of defects during MA increases the nitrogen solubility considerably [11][12][13][14][15][16][17][18][19]. In the recent years, noticeable researches on MA of Ni-free stainless steels under a nitrogen atmosphere have been also reported [11][12][13][14][15][16][17][18][19].…”

A novel approach to quantify nitrogen distribution in nanocrystalline-amorphous alloys

“…The generation of a high density of defects during MA increases the nitrogen solubility markedly. In the recent years, noticeable researches on MA of stainless steels under nitrogen have been reported [1][2][3][4][5][6][7][8][9][10]. It has been found that in Fe-Cr-Mn-N stainless steels processed by MA, the considerable content of an amorphous phase exists [4][5][6][7][8][9][10].…”

Microstructural and hardness evolution of mechanically alloyed Fe–Cr–Mn–N powders

“…In recent years, noticeable researches on MA of stainless steels under a nitrogen atmosphere have been reported [8][9][10][11][12][13][14][15][16][17][18]. It has been recognized that nitrogen has a key contribution to amorphization in this alloy system.…”

“…It has been recognized that nitrogen has a key contribution to amorphization in this alloy system. In addition, aspects of phase transformations occurring during MA, thermal behavior, and magnetic properties of the Fe-Cr-Mn-N powders have been evaluated [8][9][10][11]. However, it seems that further researches are required to be conducted on other properties, particularly on their mechanical properties.…”
