THE MECHANISMS OF PLASTIC DEFORMATION OF RAPIDLY SOLIDIFIED A13Ti AND A167Ni8Ti 25 INTERMETALLIC COMPOUNDS. Vijay K.Vasudevan*, Robert Wheeler"' and Hamish L. Fraser** *Dept. of Materials. Science.and Engineering, University of Cincinnati, Cincinnati, OH 45221 "**Dept.of Materials Science and Engineering, University of Illinois, Urbana, IL 61801 ABSTRACT The dislocation structures in rapidly solidified A13Ti with the DO 22 structure and the ternary Al-25Ti-8Ni (at.%) alloy with the L1 2 structure deformed in compression in the temperature range of 25 to 800"C have been studied by transmission electron microscopy. The room temperature deformation microstructure of the A13 Ti compound is characterized by the presence of stacking faults/order twins on ( 111 ) planes bounded by partial dislocations with Burgers vector b=1/6
