...E. A. Baxevani; A. E. Giannakopoulos The present paper presents a relation between the vickers hardness HV and the loading stiffness C of instrumented vickers indentation of metal substrates. The relation is based on the fact that the nonaxisymmetry of the plastic deformation of the vickers...

...Thao D. Nguyen; J. D. Yeager; D. F. Bahr; D. P. Adams; N. R. Moody Nanoindentation is widely used to characterize the mechanical and interfacial properties of thin film systems. However, the effects of substrate compliance on the indentation response of compliant substrate systems are not well...

... to be different from their bulk counterparts. In this paper, low- k porous silica thin films spin coated on silicon substrates are studied. The roughness of spin-on coated porous silica films is analyzed with in-situ imaging and their mechanical properties are determined using nanoindentation. A Berkovich type...

...S. Finnie; W. Cheng; I. Finnie; J. M. Drezet; M. Gremaud Laser metal forming is an attractive process for rapid prototyping or the rebuilding of worn parts. However, large tensile stress may arise in layers deposited by laser melting of powder. A potential solution is to preheat the substrate...

... with synergetic functionality that individual materials do not possess. In this study, Al 2 O 3 nanosized particles were coated on Al 2 O 3 fiber substrates using a dry mechanical coating technique employing high shear and compression forces. The materials thus synthesized had high surface area with good...

...X. Cheng; A. M. Sastry; B. E. Layton Some fundamental issues concerning the design and performance of stochastic porous structures are examined, stemming from application of advanced fibrous electrode substrates in NiMH automotive cells. These electrodes must resist corrosion and local failures...
