Microstructural Characterization of Novel Titanium Alloys Developed via a Low Cost Powder Metallurgy Process
EMSL Project ID

Abstract
With the support of the Department of Energy’s Office of Fuel Cell and Vehicle Technologies (DOE/OFCVT) Program the Pacific Northwest Laboratory (PNNL) and ADMA Products Inc. (ADMA) have recently developed several titanium alloys via a novel low cost powder metallurgy route. The alloys being developed by ADMA has a projected cost that could meet the stringent demands of the automotive industry and reduce the mass of high production vehicles thereby reducing the United States demand for oil. Over the past several years it has been demonstrated that P/M parts developed using TiH2 powder instead of titanium powder achieved near theoretical densities, had better control over the microstructures, lower oxygen content, flexibility to alter the chemistry of the alloys, thus aiding in development of novel low cost alloys with good chemical homogeneity. In order to further accelerate the current progress in development of such low cost titanium alloys, a combination of multiscale characterization capabilities from EMSL with the extensive alloy processing and mechanical testing capabilities in energy materials group is proposed. The micron to nanoscale characterization of the novel low cost alloys using TEM, APT and FIB is expected to provide a detailed understanding of microstructural evolution as a function of alloy processing parameters. Such an effort would help us to tailor the microstructure of these low cost alloys to meet the mechanical property requirements for high performance engineering applications in transportation and vehicle technologies possibly leading to an increased commercial adoption of our technology.
