Oxide dispersion strengthened alloys (ODS) are alloys that consist of a metal matrix with small oxide particles dispersed within it. They have high heat resistance, strength, and ductility. Alloys of nickel are the most common but includes iron aluminum alloys. [1]

2021年3月1日 · Oxide dispersion strengthened (ODS) steels are known for their enhanced mechanical performance at high temperatures or under radiation exposure. Their microstructure depends on the manufacturing process, from the nanoparticle addition to the base steel powder, to the processing of the nanoparticle enriched powder.

2019年3月5日 · 氧化物弥散强化钢(oxide dispersion strengthened steel, ODS钢)，具有优异的力学性能, 其原理是通过大量纳米尺寸的氧化物弥散强化相对基体中的位错和晶界进行钉扎来减少晶界的滑移，从而起到强化的作用.另一方面，ODS钢中存在大量弥散分布的氧化物强化相，这些强化 ...

ODS steel is an alloy in which nano-sized oxides with excellent thermal stability are uniformly dispersed in an Fe-based alloy matrix, which is significantly enhanced in high-temperature mechanical properties such as the creep strength, compared with a general alloy, due to the dispersion strengthening of the oxide as well as the solid solution ...

2021年9月21日 · The Mn-ODS steels were successfully manufactured by mechanical alloying and subsequent field assisted sintering. X-ray diffraction analysis revealed increased dislocation densities for both Mn-ODS alloys compared to a previously reported Cr–Ni-ODS steel. Formation of additional ε-phase was observed in the lower Mn alloy.
