Abstract
Examples of metallic laminates abound in history. Metallic laminates made of steel have been used to make Samurai swords. The famous iron pillar of Delhi consists of laminae of wrought iron. Other mundane examples include laminates copper/aluminum and copper/stainless laminates for use in kitchen utensils. More recently, researchers have been investigating multilayered composites consisting of metal/metal and metal/ceramic laminates. Extensive work on ultra high carbon steel (UHCS) laminates that have compositions very similar to ancient Damascus or Wootz steels, showed excellent impact properties. Results from our work on Al/SiC nanolaminates made by physical vapor deposition are presented. TEM analysis shows no reaction product at the interface between Al and SiC and a high degree of flexibility of brittle SiC layers under indentation. Cracking under indentation started at a depth of 1000 nm in SiC layers. This occurred at sites where kinks formed in SiC which appeared to occur at sites of shear localization.
