Fig. 2: TEM analysis of RCO phase and an interface with the Al matrix.
From: Secondary phase increases the elastic modulus of a cast aluminum-cerium alloy
a A 200 kV STEM HAADF of the RCO phase in the alloy taken in the [110] zone axis with an elevated level of atomic clarity. An in set of a region imaged at 60 kV showing the (b) EDS mapping results with layers of Ce and Mn atoms with Ce and Al, Cu, Ni shared sites. c A projection along the [110] direction of the RCO crystal structure matching the refined structure in Fig. 1e and the measured structure in a. d 200 kV STEM HAADF and BF images of the RCO and FCC-Al with an inset SAED image of the interface.
