通过对不同密度的Y—TZP(钇稳定四方相氧化锆多晶体)材料的力学性能(强度、韧性及硬度)和断裂时相变性能的研究,发现材料的相对密度不仅直接影响其力学性能,而且影响断裂时断口四方相向单斜相的相变量材料密度越高,相交量越大,材料密度和断裂时断口相交量共同决定了材料的力学性能

3Y-TZP ceramics of different sintered densities were prepared and studied of their mechanical properties(fracture strength, fracture toughness and Vicker's hardness). The investigation show that the sintered density not only affect the mechanical properti
