Naval Structural Materials: Requirements, Issues, and Opportunities.
Abstract
This paper presents selective examples of requirements, issues, and opportunities associated with naval structural materials. In particular, the relationships between operational capabilities and structural material requirements are examined for the following Naval systems: future high performance ships, next generation V/STOL aircraft, and conventional ships. These systems are selected for review because of the differences in their time frames for operational deployment. Because of paper length consideration, the discussions on technical issues and R&D opportunities are limited respectively to high strength marine alloys and emergent surface modification techniques of ion implantation and laser beam processing. Here the ability to control and predict an exacting trade off in engineering properties and service behavior is identified as a key technical issue in developing improved alloy systems. Moreover, ion implantation and laser beam processing offer the capability to optimize independent surface and bulk properties without the discontinuous interface of conventional coatings as well as to minimize the use of scarce or otherwise expensive materials. These discussions provide examples of structural materials development at various stages of technological maturity and therefore at various proximities from system impact. (Author)
