摘要：
Superplastic deformation of alumina ceramics was studied at 1400-degrees to 1450-degrees-C and at a strain rate of 4 x 10(-5) to 5 x 10(-4) S-1. MgO and ZrO2 were introduced to suppress dynamic grain growth. The latter was especially effective; grain growth was minimal in 10-vol%-ZrO2-containing material. Both materials were superplastically stretched under biaxial tension to 100% engineering strain with good surface finishing, demonstrating the feasibility of superplastic forming for alumina ceramics.
