在始锻温度500℃条件下，随着变形温度的升高，合金的晶粒逐渐细化，3道

Under the condition of the initial forging temperature of 500℃, with the increase of the deformation temperature, the grains of the alloy are gradually refined. The grain size of the recrystallization zone of 3 passes, 6 passes, 9 passes and 12 passes are 44μm, respectively , 2.80μm, 2.20μm and 1.49μm, when the deformation passes are greater than 6 passes, the grain refinement effect gradually weakens. As the number of deformation passes increases, the maximum texture density of the alloy gradually weakens, and the substantial weakening of the texture is due to the combined effect of the multi-directional forging rotation force axis and the dynamic precipitation phase. As the number of deformation passes increases, the alloy’s tensile strength, yield strength and elongation after fracture gradually increase. However, in the first 6 passes of deformation, the performance increase is greater, but after the deformation passes greater than 6, with the deformation As the number of passes increases, the increase in alloy performance gradually slows down.

Under the condition of the starting forging temperature of 500 degrees C, with the increase of the deformation temperature, the grain of the alloy is gradually refined, and the grain size of the 3, 6, 9 and 12 recrystration regions is 44 m, 2.80 m, 2.20 m and 1.49 m, respectively. With the increase of deformation channel, the maximum fabric density of the alloy gradually weakens, and the sharp weakening of the fabric is due to the joint action of multi-directional forging rotational force axis and dynamic desection phase. With the increase of deformation channel, the anti-pull strength, yield strength and elongation rate of the alloy gradually increase, but in the first 6 deformation, the increase of performance is larger, but after the deformation channel is greater than 6, with the increase of deformation channel, the increase of the performance of the alloy gradually slows down.

At the initial forging temperature of 500 ℃, with the increase of deformation temperature, the grain size of the recrystallized zone is 44 μ m, 2.80 μ m, 2.20 μ m and 1.49 μ m in 3 passes, 6 passes, 9 passes and 12 passes respectively. When the deformation passes are greater than 6 passes, the grain refinement effect is gradually weakened. With the increase of deformation passes, the maximum texture density of the alloy decreases gradually, which is due to the joint action of multi-directional forging rotating force axis and dynamic precipitates. With the increase of deformation passes, the tensile strength, yield strength and elongation after fracture of the alloy increase gradually, but in the first six passes, the increase of properties is larger, but after the deformation passes are greater than 6, the increase of properties of the alloy gradually slows down with the increase of deformation passes.<br>
