Abstract:From September 2016 to December 2017, the Federal Railroad Administration’s (FRA) Office of Research, Development and Technology funded a research investigation by, conducted by Transportation Technology Center, Inc. (TTCI) to study two types of improved truck casting materials under this Phase I effort. The first type of improved material was designated as ultraweldable, which would not require preheating or postheating during manufacturing or reconditioning. The second type was for a specific application: finding materials that would retain their ductility at low temperature services. The ultraweldable steels and the low service temperature steels were separate, but parallel objectives of the investigation were not required to meet both sets of criteria.
