Abstract

Observation of dislocation configurations was conducted for aged and compressive deformed (Ni64Al36) FeMoB alloy after hot isostatic pressing (HIP). It is shown that short and straight parallel dislocations are present in the matrix of NiAl alloy. Long and tortuous dislocations and superdislocations appear in the 1%-deformed specimen. As the compressive strain increases to 2.6%. high-densities dislocations appear in and between the deformation bands. The dislocations become tangled up in the specimen compressed to a strain of 6.2%.
