CompuTherm, LLC in collaboration with Oak Ridge National Laboratory proposes to develop a modeling tool that can be used to understand the effect of Ti, Zr, and Hf addition on the improvement of ductility of the (Mo) phase in the Mo-Si-B system. The tool will be developed by integrating thermodynamic modeling with mechanical testing. Thermodynamic descriptions of the Mo-Si-B-X (X=Ti, Zr, Hf) syste ...

In Phase I, technical and commercial feasibility was demonstrated for the application of friction stir processing (FSP) following by superplastic forming (SPF) of a 5083 aluminum alloy, and for FSP following by room temperature bending. An application showing significant promise for FSP followed by SPF is an aluminum water tight door. The use of FSP followed by SPF enables a significant part co ...

Friction Stir Welding (FSW) has been demonstrated to provide significant benefit for Naval applications. However, its use has been limited to fabrication of panels, because no portable multi-axis FSW solution exists. If FSW could be used for in situ fabrication of complex assemblies, significant further benefits could be realized, including cost reduction and improved quality (significantly less ...

Friction Stir Processing (FSP) has been demonstrated to generate refined microstructures, resulting in improved material properties. This has several areas of application. First, FSP can enhance the formability of the particular alloy of interest. This is especially important for the superplastic forming process, where the use of FSP can be used to create superplastic behavior at high strain r ...

This proposal addresses the need for an innovative and affordable material system that mitigates low frequency acoustic radiation through the hull induced by airborne noise in shipboard compartments containing Electronic Modular Enclosures. The proposed low frequency acoustic mitigation treatment is based on multiply-tuned, micro-sized absorbers embedded into a viscoelastic polymer matrix with a ...

The development of a straight vegetable oil (SVO) blending technology for combustion in boilers and in diesel engines is proposed. The overall objective of the proposal is to address the problems associated with using SVO as fuel; such as high viscosity, poor low temperature flow behavior, fuel inject and combustion chamber carbon deposition and engine power loss due to long term use. Vegetable oi ...

The objective of this proposal is to develop advanced radiation transport modeling techniques that accurately and efficiently treat transport in media having widely varying optical properties; in particular, hot gases and plasmas with optical depths ranging from the optically thin to the optically thick regimes. In doing this, we will develop a hybrid diffusion-Monte Carlo (HDMC) model that effic ...

In order to optimize training effectiveness as well as the contribution of a participating simulator in a live-virtual-constructive (LVC) driven synthetic environment exercise, a method is needed to overcome the overloading of instructors in being able to manage the amount of information available in the synthetic environment with the training needs and capabilities/limitations of the simulator(s) ...

The objective of this proposal is to further develop IV-VI PbSnSe detectors epitaxially grown on Si substrates. The motivation of fabricating IV-VI detector arrays on Si is based on the following advantages of IV-VI Pb-salt semiconductors. (1) The large dielectric constant helps screen and localize the defect related effects. (2) The epitaxial material on Si is highly uniform, and thus the cutoff ...

The high strength to weight and elasticity properties of spider silk make it of significant interest for the production of advanced fibers for military and civilian applications. Plants may offer the only feasible mechanism to produce quantities of spider silk proteins sufficient to sustain large scale manufacturing of these high performance fibers. Successful implementation of bioengineered spid ...
