Large DS castings with 430 mm in length were produced by optimizing the processing parameters. The microstructure, heat treatment response and typical creep rupture properties of the large casting were analyzed. Results of the preliminary casting trials of large blades were also reported. Key words:  superalloy      directional solidification      liquid metal cooling      blade      Received:  27 September 2010      Fund:  Supported by National Natural Science Foundation of China (No.{\footnotesize\it 50931004}), National Basic Research Program of China (No. 2010CB631201) and National High Technology Research and Development Program of China (No.2008AA05A302) Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors ZHANG Jian SHEN Jian LV Yu-Zhang LOU Lang-Hong URL:  https://www.ams.org.cn/EN/10.3724/SP.J.1037.2010.00509     OR     https://www.ams.org.cn/EN/Y2010/V46/I11/1322 [1] Seth B B.
