Abstract
The green body of 316L stainless steel powders was prepared by gelcasting technology using agar as gel.The effects of metal powder content,agar content,dispersant content and dry environment of the green body on dried body propertie were investigated by the analysis of bending strength,shrinkage and surface quality of the green body.The results show that the bending strength of the green body could reach 2.7 MPa under the conditions of the metal powders content 55vol%,gel content 0.7wt% and dispersant content 1wt%.The surface quality would be improved as the green body was dried in the environment where the temperature and moisture were controllable.
