STRUCTURAL METALS AND ALLOYS PROGRAMME

SMAP

The development of new structural metal alloys can be expected to significantly impact the industrial sectors of aerospace, oil and gas, marine and offshore, and precision engineering, amongst others. Additionally, a comprehensive metallurgical knowledge and research base within the Singapore's scientific ecosystem is critical for advancing the manufacturing industry. Keeping this in view, a thematic five year programme titled " Structural Metals and Alloys ,"under RIE2020's Advanced Manufacturing and Engineering domain is launched with the key objective of developing a world class advanced metallurgy research capacity that covers the entire spectrum of structural alloy engineering within the scientific landscape of Singapore. The programme covers topics, starting from solidification processing of new alloys to secondary processing of them, detailed studies aimed at how the microstructure affects mechanical as well as corrosion properties, surface engineering, and then use such knowledge to design alloys that offer even higher performance not only in terms of strength and toughness, but also in terms of reduced densities and increased fatigue reliability. 

Developing new alloys is a multivariative process; properties depend on not only the composition but also the microstructure, which is sensitive to the manufacturing method employed. A direct consequence of this is an intrinsically large parameter space both in terms of processing and properties; the exploration of such a space via the conventional 'trial and error' approach to optimize material choices and processing conditions is time consuming and costly. By coupling the experimental work that is to be carried out in various research institutes (RIs) and universities with detailed modeling, which will use a wide spectrum of computational tools, this programme envisions to substantially reduce the time required for new alloys' from laboratory discovery to their insertion as components in service.
