Effect of small transition metal additions on alloy Al–8%Mg–4%Si superplasticity

Metallurgist, 2012
Superplasticity properties, structural features, and mechanical properties are studied at room temperature for Al–Mg–Si alloy close to the eutectic point area of a quasibinary section on the composition diagram, containing 15% of secondary eutectic phase particles, additionally alloyed with one of the transition metals, i.e., chromium, zirconium, or ...

Enhanced age-hardening behaviour in Mg?4 wt.% Zn micro-alloyed with Ca

Scripta Materialia, 2004
Abstract In the Mg–Zn system it has been shown that the addition of trace amounts of Ca can have a substantial positive influence on the precipitation process during artificial ageing. The microstructure of the modified alloy is more complex and has a much refined precipitate structure that is very stable for prolonged periods at elevated ...

Effect of the Deformation and Heat Treatment on the Microstructural Evolution and Mechanical Properties of Mg-4%Y Alloy

Defect and Diffusion Forum, 2019
This study aimed to evaluate the effects of extrusion process and subsequentheat-treatment on microstructural evolution and mechanical properties of Mg-4%Y alloy. Theresults showed that the dynamic recrystallization occurred during extrusion, the microstructure istiny equiaxial grains, the shearing stripes and parallel streamlines which distribute ...

The mechanical anisotropy of directionally solidified Mg-4 wt.% Zn alloy under compression test

Materials Science and Engineering: A, 2019
Abstract The mechanical anisotropy of directionally solidified Mg-4 wt.% Zn alloy was studied under compression test at room temperature. The results show that directionally solidified Mg-4 wt.% Zn has higher compression strength and work hardening rates when compression axis is parallel to the growth direction, which is mainly due to the formation ...

In vitro degradation and cytotoxicity response of Mg–4% Zn–0.5% Zr (ZK40) alloy as a potential biodegradable material

Acta Biomaterialia, 2013
Mg-4 wt.% Zn-0.5 wt.% Zr (ZK40) alloy was studied as a candidate material for biodegradable metallic implants in terms of its biocorrosion resistance, mechanical properties and cytocompatibility. The corrosion characteristics of ZK40 alloy were assessed by potentiodynamic polarization and immersion testing in DMEM+10% FBS solution.

Thermal Analysis during Solidification of Mg-4%.wtAl Alloy during Lost Foam Casting Process

Materials Science Forum, 2011
The lost foam casting (LFC) process utilizes the expanded polystyrene (EPS) foam pattern for the production of metallic components. The thermal degradation of the foam pattern has a significant effect on microstructure of the component. Dendrite coherency is important for the determination of the formation of the solidification structure and cast ...

Nicotine chewing gum (2 mg, 4 mg) and cigarette smoking: comparative effects upon vigilance and heart rate

Psychopharmacology, 1989
Sixteen male smokers, abstinent the morning before testing, were assessed under four conditions: placebo chewing gum, 2 mg nicotine chewing gum, 4 mg nicotine gum, and cigarette smoking. Placebo gum was administered in the cigarette condition, while sham smoking occurred in the gum conditions.

Cellular and plasma pharmacokinetics of weekly 20-mg 4?-epi-adriamycin bolus injection in patients with advanced breast carcinoma

Cancer Chemotherapy and Pharmacology, 1986
Weekly low-dose injections of 20 mg 4'-epi-adriamycin (E-ADM) were given to 12 patients with advanced postmenopausal breast cancer for at least 8 weeks. In advance, all patients were given hormonal therapy and polychemotherapy not containing anthracyclines.

Reaction dynamics of Mg(4 1S, 3 1D2) with H2: Harpoon-type mechanism for highly excited states

The Journal of Chemical Physics, 2000
Using a pump–probe technique, the reactions of Mg(4 1S0 and 3 1D2) with H2 have been measured to yield similar rotational distributions of MgH(v=0 and 1) as that obtained for the reaction of the Mg(3 1P1) state with H2. A series of measurements is conducted to clarify that the reactions are initiated directly by these higher states, rather than ...
