| 1 | Strengthening mechanisms in magnesium alloys containing ternary Ⅰ,W and LPSO phases显示文摘This study was aimed at identifying underlying strengthening mechanisms and predicting the yield strength of as-extruded Mg-Zn-Y alloys with varying amounts of yttrium(Y) element. The addition of Y resulted in the formation of ternary I(Mg_3 YZn_6), W(Mg_3 Y_2 Zn_3) and LPSO(Mg_(12) YZn) phases which subsequently reinforced alloys ZM31 + 0.3 Y, ZM31 + 3.2 Y and ZM31 + 6 Y, where the value denoted the amount of Y element(in wt%). Yield strength of the alloys was determined via uniaxial compression testing, and grain size and second-phase particles were characterized using OM and SEM. In-situ high-temperature XRD was performed to determine the coefficient of thermal expansion(CTE), which was derived to be 1.38 × 10^(-5 K^(-1) and 2.35 × 10^(-5) K^(-1) for W and LPSO phases, respectively. The individual strengthening effects in each material were quantified for the first time, including grain refinement, Orowan looping, thermal mismatch, dislocation density, load-bearing, and particle shearing contributions. Grain refinement was one of the major strengthening mechanisms and it was present in all the alloys studied,irrespective of the second-phase particles. Orowan looping and CTE mismatch were the predominant strengthening mechanisms in the ZM31 + 0.3 Y and ZM31 + 3.2 Y alloys containing I and W phases, respectively, while load-bearing and second-phase shearing were the salient mechanisms contributing largely to the superior yield strength of the LPSO-reinforced ZM31 + 6 Y alloy. | N.Tahreen D.F.

| 3 | MICROSTRUCTURAL STUDY OF Fe-Cr-Al/Al COMPOSITE COATINGS DURING OXIDATION AND SULFIDATION AT 900℃显示文摘The microstructure of a composite coating system,which was composed of an inner layer of Fe-Cr-Al and an outer layer of aluminum,was studied after it was respectively oxidized and sulfurdized at elevated temperatures. Apart from the Al2O3 scale formed on the surface,the microstructure of the composite coatings exposed at 900℃ in air for 4h was a three-layer structure. The first layer consisted of a solid solution of Cr and Fe in α aluminum and an intermetallic compound FeAl3,while the second layer was a single phase of the aluminide and the third layer still remained the same appearance as the original Fe-Cr-Al coating. The microstructural observation of the specimen tested at 850-900℃ at low oxygen pressure and high sulfur pressure for 576h revealed that the surface coatings of the specimen had transformed into a duplex structure containing an outer layer and a thicker aluminide layer beneath. X-ray diffraction results showed that the out layer was composed of Al2S3 and Al2O3 and that AlCrFe2 was the main phase composition of the aluminide layer,with a few of Al2S3 and Al2O3 accompanied. | Z.L.
