| 摘 要： | The data on nanocrystalline materials Young s modulus measurement showit to haveless value compa-ring with this of polycrystalline materials . Effective bulk Young s modulus decreases as grain size decrea-ses . One of possible and,eventually , mainfactors for this decreaseis the presence of grain-boundary phasewhere Young s modulusis different fromone for grainitself .Asit is shownin1],the application of Reuss ,Voigt and three-di mensional models for the calculation of nanocrystalline mater…
