Temperature-Dependent Material Property Databases for Marine Steels- Part 2: HSLA-65
Abstract
The Lightweight Innovations for Tomorrow (LIFT) project entitled, Robust Distortion Control Methods and Implementation for Construction of Lightweight Metallic Structures, 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, from room temperature up to nearly the alloys melting point. In addition, the temperatures associated with on-heating and on-cooling phase transformations and their variation with heating rate, cooling rate, and peak temperature are also important for the prediction of stress and distortion evolution.
