Abstract

The feasibility of improving the mechanical properties at 1700 to 1800 deg F of oxidation-resistant Fe-Al-Cr alloys by means of a refractory dispersion was explored. A literature search was conducted, preliminary experimental determinations of properties of the alloy and its oxides were carried out, and certain mathematical relations between dispersion charaeteristics and metallurgical variables were derived. The results indicate that the alloys can be strengthened sufficiently by using a dispersion with an interparticle spacing of about 2 to 3 mu . High-temperature native oxides of the Fe-Al-Cr alloy consist largely of Al/sub 2/O/sub 3/ and in theory would serve as a aatisfactory second phase. (auth)

Investigation of alloying effects in aluminum dispersion strengthened with Al$sub 2$$O$$sub 3$

Technical Report Copeland, G

Two types of alloying elements were investigated to determine if the room-temperature strength could be improved and if, through lowering the oxide content, the high-temperature ductility could be improved. Mg was investigated for its solid solution strengthening in one type alloy. The other type alloy involved further dispersion strengthening through adding Fe, Mo, Zr, Cr, V, and Ti which form highly stable intermetallic compounds with Al. Fabrication techniques were developed which produced uniform and reproducible rods for testing. Prealloyed powders were produced by atomizing the molten alloys and collecting the powders in water. This procedure produced uniform powders with amore »« less

The effect of Zr on precipitation in oxide dispersion strengthened FeCrAl alloys

Journal Article Massey, Caleb; Edmondson, Philip; Unocic, Kinga; ... - Journal of Nuclear Materials

Oxide dispersion strengthened (ODS) FeCrAl alloys are promising candidate materials for advanced nuclear reactor applications requiring high-temperature strength, corrosion resistance, and irradiation tolerance. As these alloys have increased in compositional complexity through attempts to use highly reactive elements such as Zr to refine particle sizes and optimize nanoprecipitate dispersion characteristics, much debate has ensued as to the effects of these alloying element additions on alloy properties. In an attempt to reconcile differences in nanoprecipitate distributions reported in the literature over the past decade, a detailed investigation of a recently developed ODS FeCrAl alloy with nominal composition Fe–10Cr-6.1Al-0.3Zr+0.3Y₂O₃ is presented heremore »« less

A STUDY OF THE POSSIBILITY OF REINFORCING HIGH-TEMPERATURE ALLOYS BY ADDITION OF REFRACTORY POWDERS. Period covered: April 1956 to July 1957

Technical Report Burney, J

The reinforcement of 80 Ni-20 Cr alloy by the addition of such refractory oxides as TiO/sub 2/ and Al/sub 2/O/sub 3/ was attempted. Several powder metallurgical fabrication techniques were investigated such as (1) pressing and sintering, (2) pressing and sintering followed by various working procedures, (3) internal oxidation and (4) liquid phase sintering. ln the press- sinter method of fabrication, the best stressrupture characteristics of 1600 deg F were obtained with additions of 3.0 to 4.5% TiO/sub 2/. An addition of 4.5% TiO/sub 2/ resulted in a rupture time of 29.6 hours as compared to a rupture time of 1.0more »« less

Conference Youngwon, Kim; Griffith, W

Papers are presented on the dispersion strengthening and undercooling of aluminum alloys, the rapid solidification and powder metallurgy of aluminum alloys, and the mechanical properties of Al-Ni-Mg and Al-Mn-Mg die casting alloys. Also considered are aluminum alloys with spinel for oxide dispersion strengthening, the mechanical alloying of dispersion strengthened aluminum, and fracture mechanisms in Al-Fe-X alloys. Other topics include P/M aluminum metal matrix composites, metal matrix composites produced by spray deposition, and the rapid solidification of aluminum-based ordered cubic intermetallic compounds.
The response of dispersion-strengthened copper alloys to high fluence neutron irradiation at 415{degree}C

Conference Edwards, D; Newkirk, J; Garner, F; ...

Various oxide-dispersion-strengthened copper alloys have been irradiated to 150 dpa at 415{degree}C in the Fast Flux Test Facility (FFTF). The Al{sub 2}0{sub 3} - strengthened GlidCop{trademark} alloys, followed closely by a HfO{sub 2} - strengthened alloy, displayed the best swelling resistance, electrical conductivity, and tensile properties. The conductivity of the HfO{sub 2} - strengthened alloy reached a plateau at the higher levels of irradiation, instead of exhibiting the steady decrease in conductivity observed in the other alloys. A high initial oxygen content resulted in significantly higher swelling for a series of castable oxide-dispersion-strengthened alloys, while a Cr{sub 2}0{sub 3} -more »« less
