Microstructure evolution in MA14 magnesium alloy under multi-step isothermal forging

Prediction of forging force and barreling behavior in isothermal hot forging of AlCuMgPb aluminum alloy using artificial neural network

In the present investigation, an artificial neural network (ANN) model is developed to predict the isothermal hot forging behavior of AlCuMgPb aluminum alloy. The inputs of the ANN are deformation temperature, frictional factor, ram velocity and displacement whereas the forging force, barreling parameter and final shape are considered as the output variable. The developed feed-forward back-prop...

Microstructure-sensitive investigation of magnesium alloy fatigue

Microstructure Evolution and Shaping of Friction Stir Lap Welded Dissimilar Magnesium Alloy Joint

Friction stir lap welding (FSLW) experiment has been conducted on 3mm thick AZ80 extruded sheet and 2.3mm thick AZ31B rolled sheet. The influence of the shape of the taper thread mixing head on microstructure has been discussed. Pores forming, hooked defects, interface migration, tissue distribution have been analyzed. The organization of both sides of nugget zone (NZ) is arranged diagonally ab...

Towards Superplastic Forming of Az31 Magnesium Alloy with Controlled Microstructure

A recent study on post-superplastic forming properties has shown that heating time prior to testing has a major effect on the post-forming properties of superplastically-formed AZ31 Magnesium alloy sheets. To this point, there has been very little examination into the effects of pre-heating or annealing on superplastic forming. In this work, these effects are examined using AZ31 Mg alloy sample...

Microstructure and Fatigue Characteristic of AM60B Magnesium Alloy

This paper summarizes and reviews the findings of our research on AM60B magnesium alloy conducted in past 8 years. It essentially covers three categories: microstructural study, environmental effect, and fatigue crack growth rate of AM60B. The experimental and numerical studies on the influence of casting defects on this particular material’s properties are reviewed in the first part. It has be...
