Figure 1
Tetrahedral plot depicting the mole fractions of a series Fe–Mn–Al–Ni alloys containing f.c.c.-type martensite which formed from b.c.c. parent austenite (red dots). Additionally the composition of the frequently employed Fe43.5Mn34Al15Ni7.5 is highlighted with a blue dot. For each investigated composition a backscatter Kikuchi diffraction pattern of the martensite is shown, revealing higher diffraction pattern quality for alloys with higher Mn content. |
