Embrittlement of a cr-mo2.25crlmo steel.s.emming from neutron irradiation at 270℃ is studied by virtue of small punch testing in conjunction with scanning electron microscopy. The ductile-brittle transition temperature determined by the small punch test is much lower than that determined by the standard Charpy test. There is some irradiation-induced embrittlement effect after the steel is irradiated for 46 days with a neutron dose rate of 1.05×10^18dpa/s （displacement per atom per second）.

Trace element characteristics in the diopsides of peridotite xenoliths: a l.s.r ablation-inductively coupled pl.s.a-mass spectrometry study

引用

Chinese science Bulletin 1998年第7期43卷 579-583页

作者： shaohai Chen Xinghua Zhou s. Y. O’reilly W. l. Griffin Guohui Zhang m. Zhang Chinese Acad sci Inst Geol Lab Lithosphere Tecton Evolut Beijing 100029 Peoples R China macquarie Univ Sch Earth Sci GEMOC Sydney NSW 2109 Australia

Among the various xenoliths entrained by the Cenozoic Hannuoba basal.s. peridotite is the most abundant one. The trace elements of the diopsides from the peridotite xenoliths were anal.s.d by lA-ICP-ms. The overall depletion and some heterogeneity of the continental mantle beneath northern North China craton were indicated by the characteristics of the trace elements. The ∑rEE amount in diopside correlates with the cr/(cr+Al) ratio of diopside which is indicative of xenolith’s partial melting degree. As the peridotite hosts and pyroxenite veins show similar rEE distribution patterns, the composite xenoliths are probably formed by mantle deformation, rather than by the late metasomatism of mantle fluids/mel.s.

Diffusion behavior of cr in gradient nanolaminated surface layer on an interstitial-free steel

引用

Journal of materials science & Technology 2019年第3期35卷 460-464页

作者： s.l.Xie Z.B.Wang K.lu shenyang National laboratory for materials science Institute of Metal Research Chinese Academy of Sciences school of materials science and Engineering University of Science and Technology of China

Nanolaminated structures composed of low-angle grain boundaries(lAGBs) possess high thermal.s.ability. In this paper, a gradient nanolaminated(GNl) surface layer with smooth finish was fabricated on an interstitial-free steel by means of surface mechanical rolling treatment. microstructural observations demonstrated that the average lamellar thickness is about 80 nm in the topmost surface layer and increases with increasing depth. High thermal.s.ability was confirmed in the GNl.s.rface layer after annealing at 500℃. Diffusion measurements showed that effective diffusivity of cr in GNl layer is 4–6 orders of magnitude higher than lattice diffusivity within the temperature range from 400 to 500℃. This might be attributed to numerous lAGBs or dislocation structures with a higher energy state in the GNl.s.rface layer. This work demonstrates the possibility to advanced chromizing(or other surface alloying)processes of steels with formation of GNl.s.rface layer, so that a thicker alloyed surface layer with a stable nanostructure is achieved.

Grain boundary and microstructure engineering of Inconel 690 cladding on stainl.s.-steel 316l using electron-beam powder bed fusion additive manufacturing

Journal of materials science & Technology 2019年第2期35卷 351-367页

作者： I.A.segura l.E.murr C.A.Terrazas D.Bermudez J.mirel.s.V.s.V.Injeti K.li B.Yu r.D.K.misra r.B.Wicker W.m.Keck Center for 3D Innovation The University of Texas at El Paso Department of mechanical Engineering The University of Texas at El Paso Department of metallurgical Materials and Biomedical Engineering The University of Texas at El Paso

This research explores the prospect of fabricating a face-centered cubic(fcc) Ni-base alloy cladding(Inconel 690) on an fcc Fe-base alloy(316 l.s.ainl.s.-steel) having improved mechanical properties and reduced sensitivity to corrosion through grain boundary and microstructure engineering concepts enabled by additive manufacturing(Am) utilizing electron-beam powder bed fusion(EPBF). The unique solidification and associated constitutional.s.percooling phenomena characteristic of EPBF promotes[100] textured and extended columnar grains having lower energy grain boundaries as opposed to random, high-angle grain boundaries, but no coherent l twin boundaries characteristic of conventional thermo-mechanically processed fcc metals and alloys, including Inconel 690 and 316 l *** addition to [100] textured grains, columnar grains were produced by EPBF fabrication of Inconel 690 claddings on 316 l.s.ainl.s.-steel.s.bstrates. Also, irregular 2–3 μm diameter, low energy subgrains were formed along with dislocation densities varying from 108 to 109 cm^2, and a homogeneous distribution of cr_(23)C_6 precipitates. Precipitates were formed within the grains(with ~3 μm interparticle spacing),but not in the subgrain or columnar grain boundaries. These incl.s.ve, hierarchical microstructures produced a tensile yield strength of 0.527 GPa, elongation of 21%, and Vickers microindentation hardness of 2.33 GPa for the Inconel 690 cladding in contrast to a tensile yield strength of 0.327 GPa, elongation of 53%, and Vickers microindentation hardness of 1.78 GPa, respectively for the wrought 316 l.s.ainl.s.steel.s.bstrate. Aging of both the Inconel 690 cladding and the 316 l.s.ainl.s.-steel.s.bstrate at 685?C for50 h precipitated cr_(23)C_6 carbides in the Inconel 690 columnar grain boundaries, but not in the low-angle(and low energy) subgrain boundaries. In contrast, cr_(23)C_6 carbides precipitated in the 316 l.s.ainl.s.-steel grain boundaries, but not in the low energy

Fe-si/cr multilayers with amorphous Fe-si magnetic layers and cr nonmagnetic layers were prepared by an rf-sputtering *** the thickness of the cr layers varies from 0.5 to 6 nm, the interlayer coupling oscillates periodically from ferromagnetic to antiferromagnetism. For each sample only one wide uniform resonance peak is detected by the ferromagnetic resonance. The uniform resonance field Hb and the resonance line width △H_b oscillate periodically as the thickness of the cr layers increases, which is related to the oscillation of the interlayer coupling from ferromagnetic to *** oscillation period is about 1.5nm.
