Mode, combining preliminary and final anti-flake heat treatment: loading at 600-650 °C, cooling with the furnace to 300-320 °C, exposure 2 h/100 mm, heating with the furnace to 950 °C, exposure time 0.5 h, cooling to 840-860 °C, exposure: 0.5/100 mm, air cooling to 400 °C, then oven to 200-250 °C, exposure 2 h/100 mm. Heating with the furnace to 710 °C, exposure for 0.5 h, then cooled to 590-601 °C, exposure at the initial stage of 1.5 h/100 mm, in the forging stage 6h/100mm, then cooled at 30 °C/h to 400 °C, then 15 °C/h to 150 °C (samples tangential, specify the location of the fillet sample) |
