Simulation of magnesium alloy AZ91D microstructure using modified cellular automaton method

Microstructure and corrosion characteristics of laser-alloyed magnesium alloy AZ91D with Al-Si powder.

Blown-powder laser surface alloying was performed on the magnesium alloy AZ91D with Al-Si alloy powder to improve corrosion resistance. Characterization by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and x-ray diffraction (XRD) analysis revealed that intermetallic compounds (IMCs) of Mg2Si, Al12Mg17 and Al3Mg2 were formed in the matrix of α-Mg and Al solid solutions...

Microstructure and Aging Behavior of Nonflammable AZ91D Mg Alloy

Phase equilibria of AZ91D Mg alloys for nonflammable use, containing Ca and Y, were carried out by using FactSage® and FTLite database, which revealed that solid solution treatment could be performed at temperatures from 400 to 450C. Solid solution treatment of AZ91D Mg alloy without Ca and Y was successfully conducted at 420C and supersaturated microstructure with all beta phase resolved into ...

Tensile and fatigue behavior of AZ91D magnesium alloy

Recently magnesium alloys, owing to their low density and excellent specific strength have been attractive to designers as an advanced material for coping with energy conservation and environmental pollution regulations. Much of the recent developments of magnesium alloys and processes have been driven by the requirements of the aerospace industry, although some successful ones have found appli...

Microstructure-sensitive investigation of magnesium alloy fatigue

Particle Simulation with Cellular Automaton

This study will attempt to simulate particle movement during various events (asteroid impacts, explosions, collisions) using a Cellular Automaton model and examining the forces acting on the coordinate system itself, instead of each individual particle. By dividing space into a three-dimensional grid of cubes, all the particles contained in the same cube could be treated as a solid block of mat...
