To finalize this section, I would like to mention that some papers delve into the studies of radiation tolerance of laminated composites with the thickness of layers not increasing tens of nanometers. By varying the thickness of such materials, we can investigate the main mechanisms of influence produced by interphase boundaries on the behavior of radiation defects. The irradiation of multilayered structures with the ions of inert gases first of all with helium allows for the modeling of processes that may arise during the reactor-induced irradiation of oxide dispersion-strengthened steels and alloys.

Studies on Oxide Dispersion Strengthened (OPS) ferritic steel have been started regarding weldability and new grades are developed based on EM 10 ferritic stainless-steel. 

There is extensive evidence that between 300 and 500 °C, oxide-dispersion-strengthened (ODS) refractory metal alloys (e.g.. Mo—LaaOs and Mo—Y2O3 grades) possess markedly reduced oxidation rates compared to the pure metals [1.133]. In-situ oxidation and evaluation of the binding state reveal that M0O2 dominates over M0O3 both for Mo and Mo-... 

An ability to build coded heat exchangers in a variety of nickel-based alloys, oxide dispersion strengthened alloys (ODS) and ceramic materials to address the temperature, life and corrosion issues associated with these demanding duties. 

In stainless steels for high-temperature applicahons, RE metals, chiefly yttrium, are used to improve the oxidation resistance. Yttrium is also used in ODS aUoys (Oxide Dispersion Strengthened). Yttrium oxide parhcles with grain size 50-1500 A are distributed in a matrix of some high-aUoy material. The finely dispersed Y Oj particles obstruct the dislocahon movement in the alloy and thus improve the creep properties at high temperature. The ODS ahoy is manufactured by extrusion or by HIP (Heat Isostatic Pressing).
