| Abstract: | Reviewing the development of single crystal superalloys,the principle and grain growth mechanisms of two directional solidification methods of single crystal superalloys preparation are summarized and analyzed systematically with crystallography knowledge. After comparing the advantages and disadvantage of the present technologys of the two methods thoroughly ,two new making methods of ideal single crystal with any expected crystal orientation are put forward.The purpose is to provide new ideas of perfecting the echnology of single crystal superalloy. |
