| 摘要： | The results show that for 76-mm-thick A36 alloy, a CVN toughness of 27 J could be achieved at 4 deg C at all distances from the fusion line if the heat input was kept to a minimum level consistent with modified practices. The higher strength 76-mm-thick A588 alloy exhibited lower toughness than did the A36 alloy. At 4 deg C, 20 J were compared to 27 J for A36. The 27-J transition temperature for 76-mm-thick A588 was +10 deg C. Increasing the heat input to conventional levels raised this temperature up to +30 deg C. These and related data are presented in this report. |
