The microstructure and mechanical properties of magnesium alloy AZ61wtih1% Sn addition has been studied in this paper. The results show that the addition of 1% Sn can refine the grain size and improve the microstructure morphology of β-Mg17Al12 phase. The addition of Sn can cause the formation of Mg2Sn phase in AZ61 alloy, which can effectively enhance the mechanical properties of magnesium alloy AZ61 at room temperature and 150°C.

The grain size and the distribution of crystal orientation have an important effect on the mechanical properties of wrought AZ31B magnesium alloy sheets. Because the AZ31B magnesium alloy sheets rolled by conventional rolling have a poor formability at room temperature, a new rolling technology of differential speed rolling is used to improve the mechanical properties of AZ31B magnesium alloy. The research shows that the number of twinning crystal decreases, the number of the core of dynamically recrystallized grain increases, and the grain size become fine and isotropy by differential speed rolling with the increase of the reduction and the improving of the rolling temperature to some extent. The differential speed rolling not only improves the isotropy of the basal texture and also improves the microstructure and mechanical properties.

Mg-1Mn-0.6Ce-xY (x=0, 1, 2 and 3, mass fraction, %) magnesium alloys were prepared by casting method. And the influences of yttrium on microstructure and mechanical properties of the Mg-1Mn-0.6Ce magnesium alloy were investigated. The results reveal that the addition of yttrium to the Mg-1Mn-0.6Ce alloy could reduce the grain size of the as-cast alloys and improve mechanical properties during the investigated temperature range. The Mg-1Mn-0.6Ce-1Y alloy exhibits maximum ultimate strength, yield strength, elongation and the values are 152 MPa, 72 MPa and 13.4% and enhanced about 23.1%, 63.6% and 38.1% compared with those of Mg-1Mn-0.6Ce alloy at room temperature, respectively. The improvement of mechanical properties are attributed to the grain refinement and the precipitation strengthening generated by the Mg12Ce phase particles and the fine Mg24Y5 precipitations.

The effects of Y and Gd on the microstructure and mechanical properties of AZ81 magnesium alloy were studied by alloy preparation, microstructure analysis and mechanical property testing. The results show that moderate addition of Y and Gd to AZ61 magnesium alloy can obviously refine grains of AZ61 alloy, and decrease the amount of Mg17Al12 phase. With the increase of alloying elements, the tensile strength and elongation of aged AZ61 magnesium alloy at the temperature ranging of 25°C～175°C rise at first and then drop.When content of Y and Gd is up to 2.7%，the values of tensile strength of the alloy at room temperature and 175°C are up to their maximums, 254MPa and 164MPa respectively, while the elongation of the alloy are 22.9%,18.7% respectively. Y and Gd improve the mechanical properties of AZ61 alloy because of the grain refining strengthening, solution strengthening and the dispersion strengthening.

Increasing Temperature

The effects of heating rate and annealing temperature on the microstructure and mechanical properties of cold rolled Al-Si, low C non-oriented electrical steels are investigated using SEM metallography and uniaxial tensile tests. The experimental results show that short term annealing at temperatures up to 850 °C result in microstructures consisting of recrystallized ferrite grains with sizes similar to those observed in industrial semi-processed strips subjected to long term batch annealing treatments. Within the temperature range investigated, the grain size increases and the 0.2% offset yield strength decreases with increasing temperature. It was observed that the rate of change of grain size with increasing temperature increases when annealing is performed at temperatures greater than Ac1 (~870 °C). This effect is attributed to Fe3C dissolution and rapid C segregation to austenite for annealing temperatures within the ferrite+austenite phase field. This leads to faster ferrite growth and formation of pearlite when the steel is finally cooled to room temperature. The presence of pearlite at room temperature decreases the ductility of samples annealed at T > Ac1.

Microstructure and mechanical properties of bulk nanocrystalline Fe3Al based alloy with 10 wt. % Mn prepared by aluminothermic reaction after annealing at 600, 800 and 1000°C for 8 h were investigated in order to gain insights in effects of annealing. Crystal structure of the alloy did not change and a fiber phase with enriched Mn appeared in the annealed alloy. Grain size of the alloy changed a little after annealing at 600°C but increased a lot after annealing at 800 and 1000°C. The annealed alloy had plasticity in compression at room temperature and the alloy annealed at 1000°C had yield strength of 782 MPa. The alloy without annealing has creep properties in compression at 800 and 1000°C and can be easily hot rolled to strip and sheet.

AbstractThe effects of Bi on the microstructure and mechanical properties of AZ80-2Sn alloy were investigated. The results show that the addition of Bi within the as-cast AZ80-2Sn alloy promotes the formation of Mg3Bi2 phase, which can refine the grains and make the eutectic phases discontinuous. The addition of 0.5 % Bi within the as-extruded AZ80-2Sn alloy, the average grain size decreases to 12 μm and the fine granular Mg17Al12 and Mg3Bi2 phases are dispersed in the α-Mg matrix. With an increase in Bi content, the Mg17Al12 and Mg3Bi2 phases become coarsened and the grain size increases. The as-extruded AZ80-2Sn-0.5 %Bi alloy has the optimal properties, and the ultimate tensile strength, yield strength and elongation are 379.6 MPa, 247.1 MPa and 14.8 %, respectively.

The microstructure and mechanical properties of aged Mg-5.5Al-0.5Y magnesium alloy with Sm addition were investigated. The results show that with proper content of Sm addition, the microstructure of Mg-5.5Al-0.5Y magnesium alloy is refined obviously. The quantity of β-Mg17Al12 phase is reduced, and Al2Sm particle phase is formed. With the increase of Sm addition, the mechanical properties of the alloy at room and elevated temperature increase at first, and then decrease. When the content of Sm is up to 1%, the values of tensile strength and elongation at room temperature,150 and 175 are up to their maxima synchronously, 244MPa/20.07%, 217MPa/18.86% and 185MPa/19.15% respectively.
