Dimenzionalna analiza mikrostruktura pomoću stereomikroskopa

2009
Mikroskopija je tehnička znanost koja se bavi istraživanjem uzoraka na razini koja je nepristupačna ljudskom oku. To su uglavnom mikro i nano razine, no razvojem tehnike na području mikroskopije moguće je promatrati uzorke i na najmanjoj, atomskoj razini. Razvojem tehnike, odnosno različitih vrsta mikroskopa, nastala je mnogobrojna podjela mikroskopije

Mikrostruktura tripolifosforanu sodu otrzymanego metodą rozpyłowo-piecową

Chemik: miesiecznik naukowo-techniczny, 2011
Tripolifosforan sodu został otrzymany na drodze termicznej międzycząsteczkowej dehydratacji wysuszonej rozpyłowo mieszanki fosforanów sodu, w której stosunek molowy Na/P wynosił 1,67. Uzyskane wyniki potwierdzają, że temperatura kalcynacji jest parametrem kontrolującym skład fazowy i morfologię produktu.

Mikrostruktura akciových trhů zemí Višegrádského regionu

2011
The aim of this thesis is to compare stock exchanges in the Visegrad region with respect to the market microstructure theory, the field of economics studying the outcome of trading under specific rules. First, commonly used structures of markets are presented and the motivation why economists should be concerned with the design of markets is provided ...

Struktura i mikrostruktura indijevog oksida dopiranog kositrom

2013
Izvršena su strukturna istraživanja nanokristalnih uzorka indijevog oksida dopiranih s 0-12, 3 at% Sn kako bi se ispitao mehanizam ugradnje dopanada u ovisnosti o njihovom oksidacijskom stupnju i udjelu. Uzorci su priređeni sol-gel metodom. Ispitivanja su provedena pomoću rentgenske difrakcije u polikristalu, a mikrostruktura je određena na osnovi TEM ...

Mikrostruktura a textura titanu připraveného přáškovou metalurgií

2018
Bulk commercially pure titanium was prepared by powder metallurgy, namely by cryogenic milling and spark plasma sintering, with aim to produce ultra-fine grained material with enhanced strength. The microstructure of milled powders was investigated in detail by a novel method called transmission EBSD, which allowed the first direct observation of ...

Mikrostruktura a vlastnosti moderních plynule odlévaných hliníkových slitin.

2014
Three aluminium alloys from AA3003 series modified by zirconium were pre- pared by twin-roll casting. The role of composition, heat treatment and deforma- tion by cold-rolling or equal channel angular pressing on evolution of microstruc- ture and mechanical properties were studied.
