After preaging at 100℃for 24 h, retrogression at 200℃for 7 min, and reaging at 100℃for 24 h, the ultimate tensile strength, yield strength and elongation of the alloy are 795 MPa, 767 MPa and 9.1%, respectively. Meanwhile the failure time of the alloy applied to tensile strength of 210MPa in 3.0%NaCl+0.5%H2O2corrosion condition is longer than 720 h. The corresponding TEM observation shows that after retrogression for 7 min and re-aging treatment, the microstructure of grain boundary is similar to that treated in the T73 condition with coarsen and isolated distribution, and the microstructure inside grain is similar to that treated in the T6 condition with small and homogeneous distribution.

The waste combustion in the waste bed and the impacts of the waste burning efficiency are complex. In order to solve this problem, the method of numerical simulation has been adopted to simulate waste combustion, and calculate the mass loss rate, moisture evaporation, volatile release, char burning rate. Used the total flow rate of primary air between 50～1 000 Nm3/min to calculate the mass loss, excess air coefficient of waste bed, components of the gas. Calculated results show that the burning efficiency is higher when the total flow rate of primary air is at 517.47～632.09 Nm3/min .
