| Abstract: | In press forging process,the shattercrack of 3YC4l alloy casting has been investigatedby electron probe X-ray microanalyzer,transmission electron microscope and metallomicroscopy.The cracked causes have been found that there are alot of alloying carbide in base structures.Thecracked mechanism has been probed.The technolo-gy measure have been put forward for preventinghot forging crack and the result is good in forging. |
