Temperature-Dependent Material Property Databases for Marine Steels-Part 4: HSLA-100

Abstract

The Lightweight Innovations for Tomorrow (LIFT) project entitled, Robust Distortion Control Methods and Implementation for Construction of Lightweight Metallic Structures ICME Extension to Advanced Alloys, sought to address distortion issues with thin-plate steel fabrication of U.S. Navy ships. Integrated Computational Materials Engineering (ICME)-based tools and techniques were identified as the best path forward for distortion mitigation through computational simulation of the welding process. ICME tools require temperature-dependent material properties to achieve accurate computational results for distortion and residual stress. Properties of note include specific heat, thermal conductivity, coefficient of thermal expansion, elastic modulus, yield strength, and flow stress of alloys from room temperature to near melting plus on-heating and on-cooling phase transformations. The testing plan included some of the most common marine steels used in the construction of U.S. Naval vessels; namely, DH36, HSLA-65, HSLA-80, HSLA-100, HY-80, and HY-100. Material testing for each of the six steel grades was performed jointly by the Welding Engineering Program within the Department of Materials Science and Engineering at the Ohio State University (OSU) and the Welding, Processing, and Nondestructive Evaluation Branch at the Naval Surface Warfare Center, Carderock Division (NSWCCD). The material property data was then sent to ESI for adaptation for use in their welding-based, finite-element analysis (FEA) software colloquially known as SYSWELD. This report is part of a seven-part series detailing the pedigreed steel data. The first six reports will report and discuss the material properties for each of the individual steel grades, whereas the final report will compare and contrast the measured steel properties across all six steels, while also comparing them to the available literature data. This report will focus specifically on the data associated with HSLA-100 steel.
