DISCRIMINATING METHOD OF CASTING STRUCTURE BY ULTRASONIC WAVES |
| 摘要 |
PURPOSE:To measure the ratios of colum nar grains and equiaxed crystal grains forming casting structures and let these be reflected in processes from continuous casting process up to final products by letting ultrasonic waves be propagated in the specimen and measuring the velocities of sound and ultrasonic damping constants. |
