magnesium alloys exhibit different welding perf ormance due to their different metallurgical and thermophysical properties. For example, die cast AZ91D has a lower thermal conductivity of 51 W/m K as compared with 139 W/m K for wrought AZ21A alloy. Thus,
High strength aluminium magnesium alloy AA 5052-H32 cold rolled plates of size 100 mm × 50 mm × 6 mm were used for experiments. The chemical composition of the metal is shown in Table 1. Wire brushing is used for cleaning the adjoining surfaces

Joining/Welding Aside from designing new alloys and materials, understanding how to process them and join them is also a critical factor to consider before the new materials can be deployed. Sometimes, for example in the case of nickel aluminides, there can be a substantial delay in fully deploying these alloys due to the lack of appropriate welding processes and filler wire technologies.
1978/3/14· Results which were obtained from carrying out similar welding operations between aluminum alloy 6061-T6 and magnesium alloy ZK60A-T5 are set forth in Table III.

In this paper, we present experimental results about 5 kW CO 2 laser welding of 4 mm-thick magnesium alloy plates provided by Eurocopter France. The focused laser beam has about 0.15 mm of diameter. We have investigated the following sample: WE43, alloy recommended in aeronautic and space appliions, is constituted with Mg, Y, Zr, rare earth.
Metallurgical features are investigated, such as, the diffusion of initial precipitates and changes of grain size in the heat affected zone and thermal-mechanically affected zone, resulting from the thermal-mechanical cycle of the friction stir welding process.

Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are called alloys. Metallurgy encompasses both the science and the technology of metals. That is, the way in which science is applied to the production of

In both cases, the designed coating alloy was effective in changing the Al-Mg reaction path by forming the mechanically superior (Al,Zn)49Mg32 phase as a substitute for Al3Mg2. The FSS welds prepared with the Zn containing coating alloy exhibited a 6 % increase in lap shear strength, compared to the conventional Al - Mg welds.
magnesium alloy will occur if they melt simultaneously (Ref. 3). The maximum solid solubility of Fe in Mg is only 0.00041 at.-%. Therefore, they do not react with each other or mix at aient pressure (Ref. 10). As a result, metallurgical bonding of Mg and Fe will
