Precipitate strengthening of pyramidal slip in Mg–Zn alloys
نویسندگان
چکیده
The mechanical properties of Mg-4wt.% Zn alloy single crystals along the [0001] orientation were measured through micropillar compression at 23 °C and 100 °C. Basal slip was dominant in solution treated alloy, while pyramidal occurred precipitation hardened alloy. Pyramidal dislocations pass precipitates by forming Orowan loops, leading to homogeneous deformation a strong hardening. predictions yield stress based on model reasonable agreement with experimental data. presence rod-shape perpendicular basal plane leads reduction plastic anisotropy Mg.

Interfacial structures and energetics of the strengthening precipitate phase in creep-resistant Mg-Nd-based alloys
The extraordinary creep-resistance of Mg-Nd-based alloys can be correlated to the formation of nanoscale-platelets of β1-Mg3Nd precipitates, that grow along 〈110〉Mg in bulk hcp-Mg and on dislocation lines. The growth kinetics of β1 is sluggish even at high temperatures, and presumably occurs via vacancy migration. However, the rationale for the high-temperature stability of precipitate-matrix i...
متن کاملStrengthening Mechanisms in the Aged 2024 and 7075 Aluminium Alloys
Aluminum 2024 and 7075 alloys which are widely used in aerospace and marine applications were chosen to investigate their strengthening mechanisms. Using differential thermal analysis (DIA), metallography and tension tests, the best solutionizing conditions were determined to be 500±5°C and 2 hours for 2024 and 480?±5°C and 1 hour for 7075 alloy. Aging was performed in the range of 100 to 200°C...

متن کاملTowards resolving the anonymity of pyramidal slip in magnesium
Plasticity in magnesium crystals oriented for c-axis compression has been usually attributed to 〈cþa〉 dislocation slip on second-order pyramidal {112̄2} planes. Through molecular dynamics simulations, we investigated the formation and slip characteristics of 〈cþa〉 dislocations on second-order pyramidal planes. It is shown that the critical c-axis compressive stress for these dislocations is almo...
متن کاملSome aspects of cross-slip mechanisms in metals and alloys
2014 Dislocation cross slip in FCC and HCP metals has been described in terms of various models. The development of these models is reviewed and their predictions are compared with recent experimental observations. Some macroscopic features of plastic deformation (creep activation energies, strength anomalies and deformation stages) are examined in the light of these microscopic mechanisms. J. ...
