Evaluating the Characteristics of Cast AZ91 Magnesium Alloy for Upset Protrusion Joining Method

Increasing pressures on automobile weight reduction, driven primarily by the need to reduce CO2 emissions, are driving increased use of light metal alloys, especially magnesium and aluminum. For the automotive industry, it is imperative to develop a process that provides practical, robust, and cost-effective joining of magnesium alloys (especially castings) to each other and wrought materials and dissimilar materials at high process rates. The …
