“…The cryomilling process takes advantage of cryogenic temperatures and conventional mechanical alloying. During this process, the alloy powders are milled in an attrition ball mill vessel under liquid nitrogen at cryogenic temperature [35]. There are several advantages to cryomilling compared to conventional mechanical alloying [34][35][36][37][38][39].…”

“…In the melt spinning process, a molten alloy is pressurized and sprayed onto a spinning drum to attain a rapid cooling rate inside a vacuum chamber, and the products come out as continuous thin ribbons and are collected on the other side of the chamber [35]. Due to the rapid cooling rate, melt spinning has been used to obtain supersaturated solid solutions containing fine precipitates.…”

Nuclear energy is a low-carbon, safe, efficient, and sustainable clean energy. The new generation of nuclear energy systems operate in harsher environments under higher working temperatures and irradiation doses, while traditional nuclear power materials cannot meet the requirements. The development of high-performance nuclear power materials is a key factor for promoting the development of nuclear energy. Oxide dispersion strengthened (ODS) steel contains a high number density of dispersed nano-oxides and defect sinks and exhibits excellent high temperature creep performance and irradiation swelling resistance. Therefore, ODS steel has been considered as one of the most promising candidate materials for fourth-generation nuclear fission reactor cladding tubes and nuclear fusion reactor blankets. The preparation process significantly influences microstructure of ODS steel. This paper reviews the development and perspective of several preparation processes of ODS steel, including the powder metallurgy process, improved powder metallurgy process, liquid metal forming process, hybrid process, and additive forging. This paper also summarizes and analyzes the relationship between microstructures and the preparation process. After comprehensive consideration, the powder metallurgy process is still the best preparation process for ODS steel. Combining the advantages and disadvantages of the above preparation processes, the trend applied additive forging for extreme manufacturing of large ODS steel components is discussed with the goal of providing a reference for the application and development of ODS steel in nuclear energy.

“…In addition, the efforts have been made to prepare other materials in the bulk form using cryomilled powder. Kim et al [132,152] have reported the investigation on the effect of milling temperature to synthesize oxide dispersion strengthened (ODS) steels [152][153][154] at three different temperatures, such as room temperature, -70 and -150 o C. The mixture of Fe-14Cr-3W-0.4Ti was cryomilled along with Y2O3 for 40 hours at three different temperatures. The results reveal that as temperature decreases, particle size also undergoes reduction (summarized in Table 4).…”

The milling of materials at cryogenic temperature has gained importance both in academic as well as the industrial community in the last two decades, primarily because of significant advantages this technique as compared to milling at room temperature; environmental friendly nature, cost-effectiveness, rapid grain refinement, less contamination, and large scale production capability of various nanomaterials. Scientifically, milling at cryo-temperature exhibits several distinct material related phenomena; suppression of recovery and recrystallization, predominant fractures over cold welding, significantly low oxidation, and contamination, leading to rapid grain refinement. Cryomilling has extensively been used to obtain finer scale powder of spices for the preservation of aroma, medicines for effective dissolution, or amorphization. It has been considered an environmentally friendly process as it utilizes benign liquid nitrogen or argon without discharging any toxic entity to the environment, making the process attractive and sustainable. The present review is intended to provide various scientific as well as technological aspects of cryomilling, environmental impact, and future direction.

“…The high number density (particle densities of 10 23 /m 3 ) of coherent/semi-coherent oxide particles or clusters has been identified as the main source of the enhanced microstructural thermal stability observed with these ODS alloys [1,14]. A discontinuous distribution of fine oxide particles throughout an alloy matrix works to efficiently obstruct dislocations movement and impede grain boundary motion, specifically at elevated temperatures and while the material is being deformed [15]. While much attention in preparing and processing ODS alloys has focused on yttria, Darling et al have proven the use of zirconia to be an effective alternative resulting from the following: Zirconium has a high affinity for oxygen, resulting in the ability to form oxides.…”

An oxide-dispersion-strengthened (ODS) nanostructured FeNiZr alloy was fabricated via high energy mechanical alloying, and subsequently consolidated by the field assisted sintering technique (FAST). A range of input parameters: Temperature, hold time and pressure were evaluated in an effort to optimize the mechanical response of the material. Improvements in density, up to 98.6% of theoretical, were observed with increasing consolidation temperature and hold time at the cost of decreasing hardness values resulting from microstructural coarsening. Hardness values decreased from 650 to 275 HV by increasing processing temperatures from 750 to 1100 °C. The relationships between the varied processing parameters, microstructure and the experimentally measured yield and ultimate tensile strengths are discussed. Specifically, the effect of varying the temperature and hold time on the resulting porosity, as observed via scanning electron microscopy (SEM) in tensile and compression samples, is emphasized.
