| 1 | USING HIGH Mg-CONTENT CORED-WIRE TO SPHEROIDIZE AND DESULPHURIZE DUCTILE IRON MELT IN INDUSTRIAL EXPERIMENTS显示文摘Mg-content cored-wire was used to desulphurize and spheroidize ductile iron melt in industrial experiments. The optimal feeding speed and suitable treatment temperature were determined in the experiments. And cored-wire method and pouring method were compared. Conclusions have been drawn that, under these conditions in the experiments, the optimal feeding speed is 15m/min, treatment temperature should be as low as possible, 1400-1450℃ generally; and cored-wire method can act more effective in ductile iron melt desulphurization and spheroid than pouring method. | R.Z.Wu B.D.Sun H.J.Ni Y.B.Wu H.S.Wu J.G.Ge | 2004 | Acta Metallurgica Sinica(English Letters)2004，17，6： | 2 |

| 5 | Microstructure and Mechanical Property of Hot-Rolled Mg-2Ag Alloy Prepared with Multi-pass Rolling显示文摘A conventional multi-pass rolling is designed to form different microstructures in a Mg-2Ag alloy.The relationship between microstructure and mechanical property is investigated.The result shows that twin-induced nucleation plays a prominent role for the dynamic recrystallization(DRX)behavior of the rolled Mg-2Ag alloys.The DRXed grains distributed around elongated grains have random orientations but gradually turn to the concentrated orientation with strong basal texture when the rolling pass increases.The yield strength and ultimate tensile strength of rolled Mg-2Ag alloy gradually increase with increasing rolling pass.The elongation of rolled sample is gradually improved when the rolling pass increases from one to three,while a significant drop of elongation shows in the four-pass rolling sample.The strong basal texture,refined grains,high-density dislocations,and Ag segregation along grain boundaries are suggested to play a prominent role for enhancing the strength of Mg-Ag alloys,while the low-density dislocations,homogeneously fine-grained microstructure,and weak texture are critical for improving the ductility. | H.Zhang H.L.Hao G.Y.Fu B.S.Liu R.G.Li R.Z.Wu H.C.Pan | 2023 | Acta Metallurgica Sinica(English Letters)2023，36，2： | 1 |
