The trend of lightweight multi-material design (MMD) is becoming increasingly significant in the transportation sector, particularly in automotive applications. This trend is driven by the growing demands for sustainability, cost optimization, and performance enhancement. Multi-material design involves the strategic integration of different materials within a single component to meet specific technical requirements while enabling the production of economically efficient, lightweight parts. By leveraging the complementary properties of various materials, engineers can optimize the structural integrity, weight, and cost of vehicle components, leading to improved overall performance and resource efficiency.
Al/Fe bimetallic composites, as one of the multi-material series, offer a favorable combination of high strength and wear resistance from Fe (steel/cast iron) and high thermal conductivity, corrosion resistance, and lightweight properties from Al (aluminum alloys/ pure aluminum). This month, you will experience the metallographic preparation of these components, from cutting to fine polishing.
