摘要
Abstract
Single crystal blade ceramic shells were made from EC95 powder, silica sol binder, cgrundum sand stuccoed by sand rain machine. And the ceramic shells were used in casting test. The high temperature bending strength, high temperature creep property and the phase transition of shell in high temperature were studied by use of strength analyzer, SEM, XRD. The results show that with the increase of the temperature, the bending strength of the shell had the lowest value at 1 300 ℃, and the highest value appeared at 1 400 ℃. Casting experiments show that it is the basic requirement of casting that bending strength of shell at 1 550 ℃ is more than 6.2 MPa.关键词
