Deformation Structures in Oriented NiAl and CoAl Single Crystals Deformed at Elevated Temperature
Published online by Cambridge University Press: 01 January 1992
Abstract
The deformation characteristics of the B2 intermetallic alloys NiAl and CoAl have been examined using single crystals deformed at 673 K in the <110> orientation. Slip trace analysis and transmission electron microscopy was used to characterize the deformation process. While many aspects of the deformation are similar, some distinct differences were observed. All of the alloys were found to deform by <001> slip. NiAl was found to deform by slip on a combination of {110} and {100} slip planes with the predominant slip plane being a function of alloy stoichiometry. In contrast, CoAl was found to deform by slip only on {100} planes.
