Light alloys (Mg, Al) are of strategic importance in transport applications (automotive, aerospace) for weight reduction leading to reduced greenhouse-gas (GHG) emissions, fuel economy and improved performance. The growing CO2 emissions from the transportation sector currently contribute 25% of Canada's total greenhouse gas (GHG) emissions and the government has targeted a 45-65%reduction in GHGs by 2050. The automotive industry has long-term goals in vehicle-weight reduction for fuel economy, performance and reduced emissions, which need to be balanced with cost targets and reliability. Magnesium and aluminum offer attractive weight-reduction opportunities. The current interest in light alloys is diversified. Automakers wish to push the limits of Mg and Al alloys to be able to achieve weight reduction in strategic engine and body applications. Aircraft manufacturers aim at the potential use of magnesium in the long term for airframeand cabin components to improve the performance, load capacity and fuel economy of the carriers. In the field of aluminum, the research needs for the automotive industry are more specific. New alloys with improved high-temperature performance are needed for use in the diesel engine. This requires the development Al alloys with improved creep and elevated temperature strength. In this research program, creep resistance of Mg will be improved to meet the requiremnts of the automotive engine; a systematic program will be undertaken to develop Mg wrought alloys with improved room temperature formability for automotive body applications; and ignition resistance of Mg will be improved for aerospace applications which would lead to policy changes in the use of Mg alloys for aircraft cabin applications. At the same time novel Al alloys which can withstand the diesel engine-block service conditions will be developed.

轻合金（Mg、Al）在运输应用（汽车、航空航天）中具有战略重要性，可减轻重量，从而减少温室气体（GHG）排放、提高燃油经济性和性能。交通运输部门不断增长的二氧化碳排放量目前占加拿大温室气体（GHG）排放总量的25%，政府的目标是到2050年将GHG减少45- 65%。汽车行业在减轻车辆重量方面有着长期目标，以实现燃油经济性、性能和减少排放，这需要与成本目标和可靠性相平衡。镁和铝提供了有吸引力的减重机会。 目前对轻合金的兴趣是多样化的。汽车制造商希望推动镁和铝合金的极限，以便能够在战略发动机和车身应用中实现减重。 飞机制造商的目标是长期使用镁作为机身和机舱部件，以提高航空公司的性能、载重量和燃油经济性。在铝领域，汽车行业的研究需求更为具体。柴油发动机需要具有改进的高温性能的新合金。 这就要求开发具有改善的蠕变和高温强度的铝合金。 在这项研究计划中，镁的抗蠕变性将得到改善，以满足汽车发动机的要求;一个系统的计划将进行开发镁变形合金与改善的室温成形性的汽车车身应用;和镁的抗点火性将提高航空航天应用，这将导致政策的变化，在使用镁合金的飞机客舱应用。与此同时，新型铝合金，可以承受柴油机机体的服务条件将被开发。
