Abstract: The effect of heat treatment conditions on martensitic transformation temperatures and linear expansion in Mg-PSZ ceramics by commercial original materials is studied. The relationship between Ms, △L/L and microstructural development of materials aged at 1300℃ and 1100℃ is discussed. The martensitic transformation curve characters of materials at 1100℃ are determined.

Key words: Mg-PSZ, 热处理, 相变膨胀曲线
