“…The potential for the synthesis of novel metastable materials, e.g., lonsdaleite [251][252][253], lechatelierite quartz [254][255][256], and similar shocked materials [69,[257][258][259] using the LDC-DAC technique cannot be overstated. Originally discovered in the rocks surrounding meteorite impacts, high-quality lonsdaleite has been somewhat elusive to synthesise in larger quantities.…”

The field of high-pressure materials research has grown steadily over the last seven decades, with many remarkable discoveries having been made. This work is part II of a three-part series summarising recent progress in laser material processing within diamond anvil cells (L-DACs); this article focuses on the practice of laser-driven dynamic compression within diamond anvil cells (i.e., LDC–DAC experimentation). In this case, materials are initially pre-compressed within diamond anvil cells, then further dynamically compressed through the use of a high-power pulsed laser, often with the intent to isentropically compress, rather than to heat samples. The LDC–DAC approach provides a novel route to much higher dynamic pressures (approaching 1 TPa), as compared to conventional static compression within a single-stage DAC (<300 GPa) and provides a route to mapping Hugoniot curves. Recent proliferation of low-cost, high-power laser sources has led to increased research activity in LDC–DAC materials processing over the last two decades. Through LDC–DAC experiments, a greater understanding of the properties/structure of cold- and warm-dense matter has been obtained, and novel material phases have been realised. In this article, LDC–DAC experimental methods are reviewed, together with the underlying physics of laser dynamic compression in confined spaces. In addition, a chronology of important events in the development of LDC–DAC processing is provided, and emerging trends, gaps in knowledge, and suggestions for further work are considered.

“…However, we recently demonstrated another method to enhance reactivity in this system by applying a technique known as mechanical activation. 14 Specifically, high-energy ball milling (HEBM) of the initial mixture of boron and titanium nitride powders produces finely mixed TiN/B composite particles with greatly increased surface contact area between the reactants, where native oxide layers, which inhibit diffusion, have been disrupted, and the overall diffusion scales necessary for reaction have been reduced by 2−3 orders of magnitude. This allowed us to develop a novel route for the synthesis of the superhard BN polymorph, cubic boron nitride, under shock-induced reaction conditions.…”

We report the results from the investigation of the mechanisms of self-sustained reaction in mechanically induced TiN/B nanocomposites. The exothermic displacement reaction, 3B + TiN → BN + TiB2, with an adiabatic reaction temperature of 1905 K, was initiated through two different means: localized thermal heating and mechanical stimulation by high-energy ball milling. Comprehensive studies strongly indicate that the chemical interaction in the system involves three main stages. Solid-state mass transfer, likely the substitutional diffusion of B into a nitrogen deficient TiN x crystal lattice, is responsible for the formation of TiB2 during the first stage of the reaction (1350–1500 K) under ambient pressure. Thermal gravimetric analysis coupled with mass spectrometry demonstrated the evolution of gas phase nitrogen from TiN during an intermediate stage of the reaction in the temperature range of 1500–1800 K. Electron microscopy results show the formation of h-BN along the pores present in the initial composite, thus indicating reaction of gaseous nitrogen with boron during the final reaction stage. In addition, propagation characteristics of an oscillatory spin combustion regime in the TiN–3B system were analyzed using high-speed infrared imaging, which suggest a strongly nonlinear spin combustion mode.
