| Abstract: | Duplex stainless steel castings are trially manufactured with the method of investment casting.The results show that the major defects of investment casting are the misrun and gas cavity,which can be prevented according to controlling the correct pouring and shell mold temperature with strengthening cooling capacity during solidification.Several different good castings without misrun and gas cavity are produced by trial production process. |
