Notch Plasticity and Fatigue Modelling of AZ31B-H24 Magnesium Alloy Sheet

SAE Technical Paper Series, 2019
<div class="section abstract"><div class="htmlview paragraph">Vehicle weight reduction through the use of components made of magnesium alloys is an effective way to reduce carbon dioxide emission and improve fuel economy. In the design of these components, which are mostly under cyclic loading, notches are inevitably present. In this study,

Excimer Laser Surface Modification of AZ31B-H24 for Improved Corrosion Resistance

Corrosion, 2015
Corrosion is an issue in Mg alloys resulting from chemical, and hence electrochemical, heterogeneity of alloy microstructures. In Mg alloy AZ31B-H24 (UNS M11311), Al8Mn5 intermetallic particles are dispersed throughout the matrix, forming microgalvanic couples.

Joint properties of friction stir welded AZ31B– H24 magnesium alloy

Materials Science and Technology, 2003
AbstractThe weldability of friction stir welded hot rolled AZ31B-H24 magnesium alloy sheet, 4 mm in thickness, was evaluated, varying welding parameters such as tool rotation speed and travel welding speed. Sound welding conditions depended mainly on sufficient heat input during the welding process.

Gluconobacter oxydans H24 Genome sequencing

2012
The elucidation of the genome sequence might provide a basis for both evolutionary analysis and improvement of the biotechnological usage of the bacterium. Gluconobacter oxydans H24 is used in the industrial production of vitamin C, which is responsible for the bioconversion reaction of D-sorbitol to L-sorbose.
