Deformation and failure mechanisms in materials become size-dependent when sample dimensions and/or microstructures approach the sub-micrometer regime. Size effects include the increase in strength of...
Imagine a house that could fit in a backpack or a wall that could become a window with the flick of a switch.Harvard researchers have designed a new type of foldable material that is versatile, tunabl...
Silver nanocrystals made by a chemical reduction of silver salts (AgNO$_3$) by sodium borohydride (NaBH$_4$) were studied using Transmission Electron Microscopy (TEM) and light scattering simulations....
Purpose: On the basis of sources and own experiments, the analysis of microstructure, properties, applications as well as material and technological problems of ferritic-austenitic steel welding were ...
Design/methodology/approach: In this study the effect of particle size distribution on refractory properties of ultra-low cement castables was investigated. Secar 71 cement was used as a binder. The ...
Purpose: Influence of austenitiziation parameters (temperature and time) on grain size and mechanical properties of low alloy cast steel have been investigated. Design/methodology/approach: The grai...
Purpose: The aim of this paper was to investigate an effect of the applied electrolyte on a composition and morphology of synthesised particles, which consist of copper compounds. Design/methodology...
In the paper notch toughness assessment of full scale testing samples (FS) form the upper bound toughness of sub-sized (SS) samples of structural carbon-manganese steels. The relations proposed by Sch...
Properties of steel depend also on its internal structure. In practice, one can distinguish between primary structure (obtained during solidification) and secondary structure (being a result of the γ ...
The densification behaviour of aluminium, iron and alumina powders under cold isostatic pressing (CIP)are examined. For this purpose, a unit which can withstand up to 650 MPa pressure was designed and...
