Large-strain monotonic and cyclic loading tests of AZ31B magnesium alloy sheets were performed with a newly developed testing system, at different temperatures, ranging from room temperature to 250 °C. Behaviors showing significant twinning during initial in-plane compression and untwinning in subsequent tension at and slightly above room temperature were recorded. Strong yielding asymmetry and...

High energy 2D X-ray powder diffraction experiments are widely used for lattice strain measurement. The 2D to 1D conversion of diffraction patterns is a necessary step used to prepare the data for full pattern refinement, but is inefficient when only peak centre position information is required for lattice strain evaluation. The multi-step conversion process is likely to lead to increased error...

Ti and solution treated Mg alloys such as AZ31B (ST), AZ61 (ST), AZ80 (ST) and AZ91 (ST) were successfully bonded at 475 °C by spark plasma sintering, which is a promising new method in welding field. The formation of Ti₃Al intermetallic compound was found to be an important factor in controlling the bonding strength and galvanic corrosion resistance of dissimilar materials. The maximum bonding...

To enhance the frictional wear performance of AZ31B magnesium alloy, a nanocrystalline layer was prepared by ultrasonic impact (UI) treatment on alloy samples, and effects different times (5 min, 10 15 min) organization resistance composite coating were studied. The findings revealed that maximum thickness about 50 μm after min time, which approximately higher than MAO coating. elemental compos...

The study was carried out on a KRUMAN-CLS1016-NC shearing machine at shear temperature of 20 °C to 250 and edge clearance 8% 10% for rolled AZ31B magnesium alloy plate with thickness 8.35 mm. height area share the bright zone in section were analyzed by macroscopic measurements super depth-of-field experiments, combined DEFORM-3D finite element simulations, optimal program determined using orth...

The mechanical response of magnesium alloy AZ31B is addressed thanks to four-point bending tests. These alloys are known have an asymmetrical behavior in tension-compression. test is, therefore, a good candidate analyze this effect because it combines the two solicitations. Digital image correlation used measure evolution strain fields during test. Measurements shift neutral line (zero strain) ...

Compared with other forming processes, Pilger cold rolling exhibits unique process characteristics and a simple production method, making it highly advantageous in terms of high-precision, high-strength, poor-plasticity alloys. Among them, the design parameters mill play significant role results, key being hole opening angle θ gap ΔK. In this study, numerical simulation model for an AZ31B magne...
