摘要
Abstract
The properties the casting plate were studied in this paper, such as, the casting defect, lamellar spacing and room temperature tensile properties of Ti-AI based plate by graphite mold and cast-steel mold, and were compared with the Ti-AI based plate by ceramics mold. The experimental results show that there was no macro and micro crack in these permanent mold casting plates at the higher cooling rate during the solidification; the lamellar spacing of permanent mold casting plate was greatly reduced, compared with that of ceramics mold casting plate, and the lamellar spacing of the graphite mold casting plate was reduced approximately one half; the lamellar spacing was decreased so that the tensile properties clearly increased, for example, the lamellar spacing of the graphite mold casting plate was reduced 0.35 \im, but the yield strength was increased 40 Mpa.关键词
