| STUDY OF ELECTROMAGNETIC STIRRING REFINING MICRO-STRUCTURES OF PIPE-LINE STEEL SAW DEPOSITS |
| |
| 摘 要： | The effects of electromagnetic stirring on the microstructures of pipe-line steel SAW deposited metal were investigated. The results shouted that electromagnetic stirring increased the number density of inclusions with 0.2-0.6μm in diameter and promoted the formation and refining of acicular ferrite within austenite grains. The low tem-perature toughness of deposited metal was improved.
