Figure 6 Cross-sectional TEM results of compressive [100] Mo in (a),
(b), (c) and (d).
To compare the orientation on the mechanical responses, TEM results for
deformed [100] and [110] Mo-14Re are presented in Figure 7 with
beam direction [110]. Only one group of parallel slips are signed in
Figure 7b. The region including slips is enlarged in Figure 7d. Although
Figure 7d shows contrast, no obvious element segregation occurs in the
boundary. Severe shear instability is observed in [110] Mo-14Re in
Figure 7f. Shear offset in the free surface cumulates to width
~ 1μm via one group of bands slipping. Although another
group of slip bands extend from left side, as shown in region C in
Figure 7f, two groups slip bands extend individually. So, the
deformations in [100] and [110] Mo-14Re are both mainly
dominated by slipping in one group of parallel bands, although slip
bands with other directions are activated in [110] Mo-14Re. As
above-mentioned, the plastic deformation in [100] Mo-42Re is
dominated by tangled slip bands, which suggests plasticity is enhanced
as Re rises.
