Grade ZE41 Magnesium Alloy

ZE41 alloy is a magnesium casting alloy containing zirconium, rare earths and zinc. This alloy is well-suited for high integrity castings that are operated at aient temperatures or up to 149 C (300 F). It is easily weldable and pressure-tight.

Showcase of welding of magnesium alloys | Centre for …

Establish the feasibility of electromagnetic welding of magnesium to magnesium, magnesium to steel and magnesium to aluminum sheets. Resistance spot welding Investigate the influence of surface conditions on the weldability of AZ31 magnesium alloy in terms of weld nugget growth, surface expulsion, joint strength, and electrode tip face stability.

Materials | Free Full-Text | Investigation of the Joining …

A novel joining technology was applied to join Fiber Reinforced Polymer (FRP) and AZ31B Mg alloy, which coined the laser-arc welding source and riveting joining methods. The design idea of the stepped rivet was proposed. The weld morphology, mechanical properties, microstructures of welds under two different rivet structures were investigated. FRP and AZ31B Mg could be joined …

treatable, and it contains magnesium and silicon. The second digit of the four shows whether the alloy is the first such alloy registered. If this is the case, the second digit will be “0”, as in 5054. Digits other than “0” indie that the alloy is a modifiion of a

Materials | Free Full-Text | Wire Arc Additive …

Wire arc additive manufacturing (WAAM) offers a potential approach to fabrie large-scale magnesium alloy components with low cost and high efficiency, although this topic is yet to be reported in literature. In this study, WAAM is preliminarily applied to fabrie AZ31 magnesium. Fully dense AZ31 magnesium alloy components are successfully obtained. Meanwhile, to refine grains and obtain

Which filler metal should you choose? - The FABRIOR

The added magnesium in 4943 filler metal also provides higher repeatable strength without relying on dilution of the base material to create a sound weld. The dilution process—in which elements in the base material coine with those in the filler metal—influences an aluminum weld’s final chemical composition and mechanical properties, including strength.

Study on heat treatment process of welded plates of …

In this paper, microstructure and mechanical properties of welded plates of VW75 magnesium alloy under different heat treatment conditions were studied. The results show that the eutectic microstructure along grain boundaries of weld zone all could decompose when the welded plates of VW75 magnesium alloy were heat treated at 480°C, 500°C and 520°C conditions.
