“…Crystallographic fractures along the {111} plane have been reported previously both for tensile testing at high temperature [8] and cyclic loading at room temperature [15]. Even if specimens subjected to low strain ranges showed non-crystallographic fractures, crystallographic deformation such as twinning were visible within the microstructure.…”

“…Comparisons of TMF behavior for di↵erent crystallographic directions are rarely seen, even though comparisons concerning other properties are sometimes found. For example tensile testing at temperatures from 20-900 C in the <001>, <011> and <111> crystallographic directions was done for the SRR99 superalloy [8]. The results showed an orientation dependent yield strength, i.e a non Schmid behaviour.…”

“…Transmission electron microscopy (TEM) observations have revealed that dislocations are initially contained in the γ matrix, whereas no dislocations were found in the γ′ precipitates [22]. Also, the TEM observations [23,24] demonstrated that dislocation motion was not found on cubic slip planes. Consequently, in this work random initial dislocations were distributed on 12 octahedral slip systems in γ phase as Frank-Read sources.…”

“…In superalloys containing (γ + γ′)-phases, a full orientation correlation is usually observed between these phases [1][2][3][4][5][6][7][8][9][10]. One of the methods to obtain such superalloys is a method of direct crystallization [11][12][13][14][15][16][17][18][19][20][21].…”
