Title: Unique Properties of Lunar Impact Glass: Nanophase Metallic Fe Synthesis

Abstract

Lunar regolith contains important materials that can be used for in-situ resource utilization (ISRU) on the Moon, thereby providing for substantial economic savings for development of a manned base. However, virtually all activities on the Moon will be affected by the deleterious effects of the adhering, abrasive, and pervasive nature of lunar dust (<20 {micro}m portion of regolith, which constitutes {approx}20 wt% of the soil). In addition, the major impact-produced glass in the lunar soil, especially agglutinitic glass (60-80 vol% of the dust), contains unique nanometer-sized metallic Fe (np-Fe{sup 0}), which may pose severe pulmonary problems for humans. The presence of the np-Fe0 imparts considerable magnetic susceptibility to the fine portion of the lunar soil, and dust mitigation techniques can be designed using these magnetic properties. The limited availability of Apollo lunar soils for ISRU research has made it necessary to produce materials that simulate this unique np-Fe{sup 0} property, for testing different dust mitigation methods using electromagnetic fields, and for toxicity studies of human respiratory and pulmonary systems, and for microwave treatment of lunar soil to produce paved roads, etc. A method for synthesizing np-Fe{sup 0} in an amorphous silica matrix is presented here. This type of specific simulantmore » can be used as an additive to other existing lunar soil simulants.« less

  • The metallic glass formability of aluminum-rich Al-Ni-Fe-Gd alloys has been systematically investigated. The critical cooling rate required to form an amorphous state in this system is generally low, and comparable to that of some of the best metallic glass formers, such as Pd-Cu-Si. Amorphous ribbons up to 0.25 mm thick can easily be produced by the single-roller melt-spinning technique. Tensile strengths as high as 1280 MPa and Young's modulus of 75 GPa have been obtained. Bulk amorphous alloys with good mechanical properties are optimized in Al[sub 85]Ni[sub 6]Fe[sub 3]Gd[sub 6]. DSC and DTA studies reveal that the glass formability ismore » unique for Al-based alloys because the reduced glass temperature T[sub rg] for Al-Ni-Fe-Gd can be as low as 0.44. This is much lower than conventional theory would suggest for easy glass forming systems. A mechanism for the unusual glass formability is suggested.« less
  • Amorphous Al[sub 80]Ni[sub 8]Fe[sub 4]Gd[sub 8] quaternary powders are successfully produced using the mechanical alloying (MA) technique, suggesting that powder metallurgy techniques may be used in the manufacture of aluminum-transition metal-rare earth metallic glasses as high-strength, low-density engineering materials. Detailed investigations into the microstructural evolution of the amorphous phase from elemental powders are presented, employing scanning and transmission electron microscopy, as well as, analytical techniques. The results show that it is possible to amorphize higher-order systems by MA, and the observations of the amorphization reaction support the interdiffusion-based model developed from studies of simple binary systems, with certain adjustments. Themore » resulting amorphous powder demonstrates good thermal stability, and consolidated amorphous bulk material up to 93% dense are easily produced. Mechanical properties of the amorphous phase are evaluated, including measurement of Vickers hardness and fracture toughness. K[sub c] is found to lie in the range of 1-5 MPa/m[sup 1/2], identifying the produced powder as the brittle-type amorphous phase seen in earlier work. Dispersed ductile nanocrystals improve the fracture toughness at the expense of Vickers hardness.« less
  • Mechanical properties and glass transition temperatures (T{sub g}) of Fe-Cr-Mo-P-C-B bulk metallic glasses containing up to 27 at. % metalloids have been studied. The shear modulus (G) is found to decrease with increasing metalloid content and a maximum plastic strain of {approx}3% is obtained, despite the increase in the number of strong metal-metalloid bonds. Also, T{sub g} increases with the decrease in G, in contrast to usual behavior. By employing first-principles calculations, the results are discussed in light of atomic bonding and connectivity in the amorphous network. The findings are relevant to understanding ductility and glass transition of metallic glasses.
  • Ferromagnetic CoFeSiB and NiFeSiB metallic glasses were produced to study the thermal and magnetic properties of glassy alloys which show the good performance for free layers in the Magnetic tunnel junctions (MTJs). The characters of amorphous materials are compared with crystalline materials composed of CoFe and NiFe. X-ray diffraction pattern was used to confirm the amorphous and crystalline state of melt-spun ribbons. The thermal stability and crystallization processes were investigated by differential scanning calorimeter (DSC). The thermal properties of amorphous alloys represent by the parameters; glass transition temperature (>580 deg. K), crystallization temperature (<830 deg. K), the large supercooled liquidmore » region ({delta}T = Tx-Tg), the reduced glass transition temperature (Trg = Tg/Tm). The alloys exhibit the soft magnet properties of high saturated magnetization (Ms), low coercive force (Hc) and high effective permeability ({mu}e) represented to the hyeteresis loops. The magnetic characters for all alloys are measured by vibrating sample magnetometer (VSM). Amorphous ferromagnetic free layers in MTJs have a lower Ms and a higher anisotropy constant than crystalline layers. The experimental results explain how the metallic glass for free layer performs better than crystal. The good combination of thermal and magnetic properties in the amorphous material indicates the possibility of application as the glassy magnetic material.« less
  • Nanophase Fe-28Al-2Cr powder was obtained by ball milling and consolidated by shock wave compaction. Fully-dense well-bonded compacts were produced with a diameter of 32 mm and a thickness of [approx]6 mm. The grain size in the compacts was [approx]80 nm. In tension, the nanophase intermetallic is brittle with a failure strength ([sigma][sub f] = 0.65 GPa) comparable to a coarse-grained intermetallic with similar composition. In compression, the nanophase material exhibits superplastic-like flow during room temperature quasistatic deformation to true strains greater than 1.4. The compressive flow strength is 2.1 GPa and no macroscopic strain hardening is observed. This behavior ismore » compared to the coarse-grained material that has a yield strength of 0.25 GPa, displays significant work hardening and little tension-compression anisotropy. TEM examination of the nanophase material before and after deformation shows a refinement of the microstructure during deformation. The microstructure refines to [approx]10 nm grains surrounded by amorphous material.« less
