硅酸盐玻璃的批量生产是基于窄范围的钠钙硅组合物，因此，通常认为机械性能随组合物的任何变化都是无关紧要的。然而，在过去50年左右的时间里，一系列作者的研究已经证明了一些有趣的性质变化，如韧性，脆性，以及更具争议的强度与成分。我们已经生产了几个系列的碱金属混合碱土金属硅酸盐玻璃，并正在评估其机械性能的变化与组合物使用传统的压痕和纳米压痕。纳米压痕研究也被用来评估这些玻璃的近表面机械性能的表面水合作用的影响。本报告回顾了我们迄今为止所获得的结果，并试图得出一些更广泛的结论，硅酸盐玻璃的机械性能的组成依赖性。(C)2010爱思唯尔有限公司版权所有。
Bulk production of silicate glasses is based around a narrow range of soda-lime-silica compositions and as a result any variation in mechanical properties with composition is normally considered to be of little interest. However, studies by a range of authors over the last 50 years or so have demonstrated some intriguing variations of properties such as toughness, brittleness and, more controversially, strength with composition. We have produced several series of alkali-mixed alkaline earth-silicate glasses and are assessing the variation of their mechanical properties with composition using both conventional indentation and nanoindentation. The nanoindentation studies are also being used to assess the effects of surface hydration on the near surface mechanical properties of these glasses. This presentation reviews the results we have obtained to date and attempts to draw out some wider conclusions concerning the compositional dependences of the mechanical properties of silicate glasses.
