Synthesis, Characterization, And Properties Of Peroxo-Based Oxygen-Rich Compounds For Potential Use As Greener High Energy Density Materials
… main aspect of high energy density material (HEDM) design is to obtain greener alternatives for HEDMs that produce toxic byproducts. Primary explosives lead azide, lead styphnate, and mercury fulminate contain heavy metals that cause heavy metal poisoning. Leaching of the widely used tertiary …

Stress relaxation of AZ31 alloy using high energy diffraction microscopy
… work, High Energy Diffraction Microscopy (HEDM) is used to explore the kinetics at the scale of individual grains by following diffraction spots during a loading increment and subsequent relaxation. The study was conducted at the Advanced Photon Source (APS) sector 1-ID-C at Argonne …

Exploration of incompatibility in Al-Li alloys using high energy diffraction microscopy and a crystal plasticity model
… in situ High Energy Diffraction Microscopy (HEDM) and polycrystal plasticity simulations to study the local evolution of lattice strains to gain insight into the development of incompatibility. The identification of factors that initiate and drive delamination fracture, such as the …

In situ diffraction investigations of mechanisms that lead to path dependent mechanical behaviours of nickel-titanium shape memory alloys
… data are collected from neutron diffraction and HEDM experiments at various loads. Three loading paths included both proportional and non-proportional mechanical loads on a cruciform sample and evolution of volume fraction can be studied independently for different paths. Different volume …

Synthesis and characterization of mechanically alloyed aluminum-based compounds as high energy density materials
A new type of metastable reactive powders for potential use as high energy density materials in propellants, explosives, and pyrotechnics was developed. These powders are intended to replace aluminum typically added to energetic formulations to increase reaction enthalpy and temperature. The new …

The synthesis and characterisation of halogen and nitro phenyl azide derivatives as highly energetic materials
… a very promising high energy density material (HEDM) the potential of which we are going to explore in more detail in future studies. In the drophammer testing of TNMA, DNTA and TNTA the order of the acoustic level is TNMA < DNTA < TNTA, but the values for DNTA and TNTA are very similar. Even …
