Microstructure effects on process outputs in micro scale milling of heat treated Ti6Al4V titanium alloys
Ahmadi, Masoud; Karpat, Yigit; ACAR, Ozgun; Kalay, Yunus Eren (2018-02-01)
This study investigates the influence of materials' microstructural characteristics, including grain size and phase fractions, in micro end milling of heat treated Ti6Al4V titanium alloys. Micro milling process conditions such as feed, depth of cut, and the cutting edge radius of the micro end mill are in the same order of magnitude as the grain size of the material, which gives rise to the anisotropic behavior of the multiphase materials and their deformation characteristics considering their grain size, g...
Microstructure characterization of heat-treated ferromagnetic steels by magnetic barkhausen noise method
Gür, Cemil Hakan (2019-01-01)
This paper presents non-destructive evaluation of microstructures of heat treated steels by the Magnetic Barkhausen Noise (MBN) method. Various steel specimens having different microstructures were produced by appropriate heat treatments. All specimens were characterized by metallographic examinations, hardness and MBN measurements. The results showed that MBN parameters are highly sensitive to the variations in the microstructure, and this method is a promising candidate for practical non-destructive chara...

Microporous patterned electrodes for color-matched electrochromic polymer displays
Aubert, Pierre-Henri; ARGUN, Avni A.; Çırpan, Ali; TANNER, David B.; REYNOLDS, John R. (American Chemical Society (ACS), 2004-06-15)
The emergence of electroactive and conducting polymers offers new opportunities for the design of materials for electrochromic devices (ECDs). Of these, poly(3,4-alkylenedioxythiophene)s (PXDOTs) and their derivatives exhibit the most promising electrochromic (EC) properties. Here, we report the use of highly porous metallized membranes which allow the production of patterned, rapid-switching, reflective ECDs. Using poly(3,4-ethylenedioxithiophene) (PEDOT), poly(3.,4-propylenedioxythiophene) (PProDOT), and ...
