Welding Magnesium : Maine Welding Company

Magnesium scrap of this type is not common to welding operations. If a magnesium fire does start, it can be extinguished with dry sand, dry powdered soapstone, or dry cast iron chips. The preferred extinguishing agents for magnesium fires are graphite base powders.

Mechanical Properties and Microstructure of AZ31B …

As described in the current article, an AZ31B magnesium alloy was processed for the first time by three different routes of I-ECAP, namely, A, BC, and C, at 523 K (250 C). The structure of the material was homogenized and refined to ∼5 microns of the average grain size, irrespective of the route used.
