摘　　要：针对Aermet100钢研究了大规格棒材锻造工艺对微观组织和力学性能的影响。研究结果表明：细化锻造过程的晶粒度有利于获得较高的断裂韧度。细化晶粒度的途径主要有锻造加工温度控制在再结晶区间和增大总变形比。Aermet100钢锻造温度区间应控制在950~1100℃之间进行,终锻温度控制在950~1000℃;总变形比之和应大于20。Research on the effect of forging process on the microstructure and mechanical behavior of ultrahigh strength Aermetl00 steel. The results show that grain refinement during forging is better for obtaining higher fracture toughness, The main passes of grain refinement include controling forging temperature in the recrystallization temperature and augmenting the total deformation ratio. The best forging temperature range ofAermet100 is 950 ℃ to 1100 ℃ , and control the finish forging temperature 950℃to 1000℃ ; The total deformation ratio should be greater than 20.
