The Indian Institute of Technology Madras researchers have developed a high-performance magnesium alloy that can replace steel and aluminium in automobiles. IIT-M said its researchers working with University of North Texas and US Army Research Laboratory Teams have developed an engineered magnesium alloy. The engineered magnesium alloy with significantly improved properties can replace steel and aluminium alloys in automotive and aerospace components. The new engineered alloy is strong, highly ductile and its super plasticity is achieved at higher strain-rates which reduces overall manufacturing time, effort and costs. In addition to this, it is also lightweight, which helps lower the carbon footprint of vehicles.

Research group is also trying to increase the load-bearing capacity of metals and alloys through microstructural engineering and processing of metals. After this feat, the team is all set to apply the same strategy of processing to other known magnesium alloys and metallic alloys with the intention of obtaining highly efficient stronger materials with superior performance.

Being one of the lightest and energy-efficient structural materials, magnesium alloys are potential candidates to replace steel and aluminum alloys in automotive and aerospace components since their density is two-thirds of aluminum and one-quarter of steel. The current industrial application of wrought magnesium alloys in structural components is very limited due to their poor moderate to low strength, poor ductility, yield strength asymmetry and lack of high strain rate super plasticity

A collaborative research project on this area was carried out by Dr Sushanta Kumar Panigrahi Associate Professor Department of Mechanical Engineering IIT Madras, Rajiv Mishra University Distinguished Research Professor University of North Texas, and Dr RC Brennan and.
