Title: Pulsed Plasma-Assisted Diffusion Bonding of ODS-FeCrAl Alloys

Abstract

The successful joining of ODS alloy PM2000 rods by pulsed plasma-assisted diffusion bonding is reported. During secondary recrystallisation after joining, the alloy grains grew across the original interface, which was then marked only by a row of remnant alumina particles. These did not appear to act as pinning sites for the grain boundaries, which moved easily past them, leaving a strong diffusion bond.

  • Cyclic oxidation testing was conducted on alloy MA956 and two different batches of alloy PM2000 at 1100 and 1200 C in different atmospheres rich in O2, H2O and CO2. Compared to 1h cycles in dry O2, exposure in air+10 vol.% H2O resulted in an increase of the oxidation rate and a decrease of the time to breakaway for all alloys at 1200 C, and a faster consumption of Al in the MA956 alloy. One hour cyclic testing in 49.25%CO2+50%H2O+0.75% O2 had a smaller effect on the oxidation rate but led to increased formation of voids in alloy MA956, which hadmore » an impact on the alloy creep resistance. At 1100 C, exposure in 50%CO2+50%H2O resulted in significant oxide spallation compared with oxidation in air, but this was not the case when 0.75% O2 was added to the CO2/H2O mixture as a buffer. The control of impurity levels drastically improved the oxidation resistance of PM2000.« less
  • In this paper, oxide dispersion strengthened (ODS) FeCrAl alloys with 12–15% Cr are being evaluated for improved compatibility with Pb-Li for a fusion energy application and with high temperature steam for a more accident-tolerant light water reactor fuel cladding application. A 12% Cr content alloy showed low mass losses in static Pb-Li at 700°C, where a LiAlO 2 surface oxide formed and inhibited dissolution into the liquid metal. All the evaluated compositions formed a protective scale in steam at 1200°C, which is not possible with ODS FeCr alloys. However, most of the compositions were not protective at 1400°C, which ismore » a general and somewhat surprising problem with ODS FeCrAl alloys that is still being studied. More work is needed to optimize the alloy composition, microstructure and oxide dispersion, but initial promising tensile and creep results have been obtained with mixed oxide additions, i.e. Y 2O 3 with ZrO 2, HfO 2 or TiO 2.« less
  • The concepts and advantages of diffusion bonding hightemperature alloys with beryllium are discussed, and a practical method for diffusion bonding is presented. Results show that beryllium is a useful primary diffuser element for diffusion-bonding iron, nickel, and cobaltbase high temperature alloys. Beryllium-transport alloys are also developed that facilitate preplacement of beryllium at interfaces between base metals to be joined. These alloys contain beryllium in solid solution at bonding temperature, and they produce diffusion- bonded joints rapidly from 1/2 to 5 min at bonding temperatures of 1940 to 2100 f F. Only intimate contact is needed between the berylliumtransport alloys andmore » the base metal members. The alloys can be easily rolled into strip stock and can be formed into complex shapes to facilitate preplacement in joints. The shear strengths of the diffusion-bonded joints qualitatively correlate with the base metal ultimate strengths and yield strengths at 1500 f F. (N.W.R.)« less
  • Nanoscale oxides play an important role in oxide dispersion strengthened (ODS) alloys for improved high temperature creep resistance and enhanced radiation damage tolerance. In this study, transmission electron microscopy (TEM) and atom probe tomography (APT) were combined to investigate two novel Fe-16Cr-3Mo (wt.%) based ODS alloys. Spark plasma sintering (SPS) was used to consolidate the ODS alloys from powders that were milled with 0.5 wt.% Y2O3 powder only or with Y2O3 powder and 1 wt.% Ti. TEM characterization revealed that both alloys have a bimodal structure of nanometer-size (~ 100 – 500 nm) and micron-size grains with nanostructured oxide precipitatesmore » formed along and close to grain boundaries with diameters ranging from five to tens of nanometers. APT provides further quantitative analyses of the oxide precipitates, and also reveals Mo segregation at grain boundaries next to oxide precipitates. The alloys with and without Ti are compared based on their microstructures.« less
  • Cyclic oxidation testing was conducted at 1200 C in O2, dry air and in atmospheres rich in H2O and/or CO2 to simulate combustion environments. The oxidation rates were significantly higher in air + 10%H2O and a mixture of O2-buffered 50%H2O-50%CO2, leading to shorter times to breakaway oxidation. Curve fitting using the COSP cyclic oxidation program confirmed that the presence of H2O results in an increase of the alumina spallation rate. The use of specimen mass gain modeling associated with the characterization of pre-oxidized specimens and in particular the determination of the remaining Al content after exposure, will allow to accuratelymore » estimate the durability of oxide dispersion-strengthened (ODS) FeCrAl alloys in combustion environments.« less
