对比不同奥氏体化温度和细化处理次数的不同细化处理工艺表明,采用D2工艺:1030℃×30min淬火+1050℃×30min淬火+1030℃×30min淬火+540℃×1h×2次,能够提高试验钢的强韧性能。
Comparison of different refining treatment processes with different austenitizing temperatures and refining treatment times shows that D2 process: 1030 ℃ × 30min quenching+1050 ℃ × 30 min quenching+1030 ℃ × 30 min quenching+540 ℃ × 1h × Twice, can improve the strength and toughness of the test steel.
