چکیده

Amounts of segregation at grain boundaries Mg-0.05at?X (X = Al, Bi, Ca, Ce, Gd, Nd, Y, Zn, Zr) alloys were calculated by using the Hillert’s boundary phase model. As a result, relatively high was obtained in each case Y and Zn. In addition, basal plane texture Erichsen value experimentally investigated, which exhibits similar tendency to previous experiments, i.e., decreases with decreasing intensity. High-angle annular dark-field STEM (HAADF-STEM) analysis Mg-0.4Nd (mass?) Mg-0.2Y sheets elucidated that uniform detected Mg-0.4Nd, while localized scattered region observed Mg-0.2Y. These behaviors explained concept critical element concentration proposed Griffiths. An un-recrystallized microstructure lattice distortion Scanning Electron Microscope - Back-Scatter Diffraction (SEM-EBSD) analysis, leads possibility Nd contributes suppression recrystallization during rolling. strong correlation between experimental intensity, amount is useful parameter for describing intensity binary Mg alloys.

Formability of Magnesium Alloys

The paper is focused on issues of processing of non-ferrous metals in practice, namely on Mg-Al-Zn based on magnesium alloys with graded Al contents. It is well known that forming of these alloys is difficult since this feature is caused by their crystallographic arrangement. Nevertheless, application of appropriate methods of forming, such as e.g. some of SPD processes, makes it possible to ac...

Ultralow Temperature Anelasticity of Aluminum-Magnesium Alloys

Results of internal friction measurements on the commercial aluminum-magnesium alloys 5052,5086 and 5486 are reported here over the temperature range 50 mK to 300 K, and compared with published data on alloy 5056. Effects of heat treatment and explosive bonds on the internal friction are evaluated. The quality factor of proposed multi-layer aluminum-alloy spherical resonant-mass detectors of gr...

Development of Lightweight, Corrosion-Resistant Magnesium Alloys Formable at Room Temperature

FINAL REPORT Background and Motivation There is a need for lightweight structural materials for transportation to improve the performance and energy efficiency. Because magnesium (Mg) is 36% less dense than aluminum (Al) (1.74 g/cm for Mg vs. 2.70 g/cm for Al), Mg-based alloys have received increasing attention lately. The limiting property of Mg and its alloys at the present time is poor ducti...
