Blackburn orientation relationship
Webcooling with the Blackburn orientation relationship of (0001)D//(111)Jand <1120>D//<110>J, control of the lamellar orientation can be achieved by controlling the orientation of the Dphase. The orientation of theDphase can be controlled during solidification by using a seed from the TiAl-Si system. WebThe Blackburn orientation relationship is strictly obeyed between the 2 lamellae and the lamellae. The phase forms a domain structure of twin-related lamellae, which themselves consist of one to three order variants. Besides the coherent twin, produced by a 180 rotation around h111i, two pseudo-twin relations exist. The pseudo-twins are ...

Web2 phases still obey the Blackburn orientation relationship, which is consistent with the conventional TiAl alloy [21]. Moreover, plenty of / lamellae can be observed in the lamellar microstructure, as shown in Figure 3c. The f domain embedded in the L lamellar structure was often observed. Detailed research on f and L has been Web0/ interface according to a Blackburn orientation relationship. In order to stabilize the microstructure, the air-cooled samples were tempered at 800–1000 C. During tempering, the microstructure decomposed mainly via an 2 0! transformation. The martensite was almost
