Kinetics of nanocrystallization in regular alternating terpolymers of ethene and propene with carbon monoxide.

Composition dependent kinetics of nanocrystallinity development in regular alternating terpolymers, of Et and Pr with CO was studied by DSC in the interval between the temperatures of glass transition at T-g approximate to 290 K, and of the onset of ...

Nanocrystallization of anatase in amorphous TiO2

The kinetics of nanocrystallization in amorphous TiO2 has been studied in non-isothermal conditions by DSC. It was found that this process could be well described by standard Johnson-Mehl-Avrami-Kolmogorov (JMA) model with kinetic exponent m...

AFM and Mössbauer spectrometry investigation of nanocrystallization process in Fe-Mo-Cu-B rapidly quenched alloy

In this paper, the effect of heat treatment on the development of nanocrystallites in rapidly quenched Fe79Mo8Cu1B12 alloy is investigated. The surface morphology is examined using noncontact mode atomic force microscopy (AFM). The results are compar...

Tribological properties of a thin film - substrate system

This part is closely tied together with the rcent one which was mostly theoretical. The text shows the results found out in practice using the Pin-on-Disc method using the different test parameters for defining atributes (weighting, radius, ball mate...

New findings in Mössbauer studies of amorphous FeMoCuB NANOPERM-type alloy

The effect of heat treatments at 603 K (a relaxation of an amorphous structure) and at 723 K (an onset of a bulk nanocrystallization) of a rapidly quenched Fe76Mo8Cu1B15 alloy is studied. The differences in sample processing are reflected in...

Photoluminescent properties of nanocrystallized zinc borosilicate glasses

Zinc borosilicate glass is studied as a scintillating material. Glass samples with zinc oxide concentrations as high as 60 mol% were prepared successfully without deteriorating the glass-forming ability. Different post-preparation thermal treatments ...

Influence of Co content on structural and magnetic properties of Co x Fe 84-x Nb 7 B 9 alloys.

Nanocrystallization of amorphous Co x Fe 84-x Nb 7 B 9 alloys (x=15,25,33) was studied by means of Mössbauer spectroscopy. Apart from nanocrystalline ferromagnetic BCC Fe-Co phase, a non-magnetic crystalline component also (Fe 1-x Co x ) 2 N...
