On the Bonding Strength of Mg-Mg and Mg-Al Material Compounds

Materials Science Forum, 2014
The dependence of different brushing parameters during surface preparation on the resulting bonding strength for the roll-bonding of Mg-Mg composites was investigated. A parameter study with different brushing parameters was used to analyze the effect on surface roughness as pre-step for roll-bonding trials with different roughness ratio.

Precipitation Processes in Mg–Th, Mg–Th–Mn, Mg–Mn, and Mg–Zr Alloys

Metal Science Journal, 1972
Abstract A study has been made of precipitation processes in selected magnesium-base alloys by means of electron microscopy. The principal part of the investigation was concerned with the effect of manganese precipitation in a Mg-Th alloy. It is shown that the sequence of precipitation in a Mg–2.0percnt; Th–1.0% Mn alloy (HM21) is not as complex as ...

Fe–Mg Interdiffusion in (Mg,Fe)O

Physics and Chemistry of Minerals, 2005
We have performed a series of interdiffusion experiments on magnesiowustite samples at room pressure, temperatures from 1,320° to 1,400°C, and oxygen fugacities from 10−1.0 Pa to 10−4.3 Pa, using mixed CO/CO2 or H2/CO2 gases. The interdiffusion couples were composed of a single-crystal of MgO lightly pressed against a single-crystal of (Mg1-x

Subdivision of the Mg‐suite noritic rocks into Mg‐gabbronorites and Mg‐norites

Journal of Geophysical Research: Solid Earth, 1983
Mg‐suite noritic rocks can be divided into two groups, the Mg‐gabbronorites and the Mg‐norites. The rocks of these groups differ in ratios of high‐Ca pyroxene to total pyroxene, compositions of pyroxene and plagioclase, assemblages of Ti‐, Nb‐, and Zr‐bearing minerals, compositions of chrome spinel, bulk‐rock Ti/Sm and Sc/Sm, and measured ages. The two

Electronic Excitations Generated by the Deposition of Mg on Mg Films

Physical Review Letters, 2010
Nonadiabatic processes are observed during growth of Mg atoms from the gas phase on Mg films. Chemicurrents are measured in thin film Mg/p-Si(001) Schottky diodes which are exposed to thermally evaporated Mg atoms. The photonic and chemical contributions to the observed reverse currents in the devices can be distinguished by varying the Mg atom flux ...

New structure information on Mg-30, Mg-31 and Mg-32

2008
The fast timing βγγ(t) method was applied to investigate the level lifetimes in 30,31,32Mg. Levels in Mg have been populated in β and β-delayed neutron emission of Na, at the ISOLDE facility. From the γγ coincidences a number of new states have been identified and new level schemes were constructed for 30 31,32Mg.

Dayglow of Mg I and Mg II

Journal of Geophysical Research, 1972
A recent paper by Anderson and Barth [1971] reports a rocket flight during which spectra of the near ultraviolet were obtained, showing the resonance lines of ionized magnesium. The observed radiance, corresponding to approximately 400 R, was interpreted to indicate a column abundance of 4 × 109 ions cm−2, which is approximately equal to that of atomic
