项目摘要
This proposal is for the continuation of research on transformation toughening in ZrO2-containig ceramics. Specifically, the research will focus on i) making dense transformation toughened Mg-PSZ with fine grain size, in contrast to the current generation of tough Mg- PSZ's which are course grained, porous, and contain unwanted second phases, ii)studying structure-property relationships in ternary Mg, Y-PSZ's, particularly probing the effect of particle morphology and hence coherency stresses, on the crack tip stress-induced transformation, iii) Studying the mechanics of stress-induced subcritical transformation which in "supertough" Mg-PSZ can occur before any visible surface microcracks, and iv) studying transformation around microhardness indents in Y-PSZ single crystals, particularly the dislocation-nucleated autocatalytic transformation.
这一建议是为了继续研究转型 ZrO_2陶瓷的增韧具体来说,研究 将集中于i)制备致密转变增韧的Mg-PSZ, 细晶粒尺寸,与当前一代的坚韧Mg相比, PSZ是粗粒的,多孔的,含有不需要的第二 相,ii)研究三元镁的结构与性能关系, Y-PSZ的,特别是探测颗粒形态的影响, 因此,在裂纹尖端应力诱导的相干应力 (三)研究应力诱导的力学 在“超韧”Mg-PSZ中可发生亚临界转变 在任何可见的表面微裂纹之前,以及iv)研究 Y-PSZ单晶显微硬度压痕附近的相变 晶体,特别是位错成核的自催化 转型
