A new method of analysis of PALS spectra of porous materials is proposed. The model considers both the thermalization process of positronium inside the pores and the pore size distribution. The new model is fitted to spectra of mesoporous silica MCM-41 and MSF. The resulting parameters are compared with parameters obtained from fitting the “conventional” models, i.e. a sum of exponential components with discrete or/and distributed lifetimes.

Focused Ion Beam Milling

Focused ion beam milling of self-assembled magnetic superstructures is demonstrated as a novel approach to fabricate porous materials with tunable porosity. During exposure to the ion beam, nanoparticles in the superstructure are subjected to combined milling and melting, thus merging together into a porous network.

A technology of hardening porous materials of titan powders has been elaborated. The technology is based on passing alternating current with duration of ~10-1…101 s through porous (35…40%) blanks made by method of Sintering by Electric Discharge (SED) by passing a pulse of current with duration of ~10-5…10-3 s. The influence of technological regimes of porous blanks treatment on their structure and properties is investigated. Geometry and dimension of contact necks between powder particles of obtained samples are evaluated. Variations of porosity and strengths as well as microstructure of porous samples materials before and after treatment are investigated. Optimum range of treatment technological regimes is determined within which porosity of 30…35% with maximum strength values.

Effect of content of Fe,Si and Fe/Si on Structure and Properties of 3014 can-body were studied by using tensile test, stamping test, SEM, XRD, etc. The results show that:(1) The sum of Cube and Goss texture in 3104 aluminum-alloy canbody is about 40%. The influence of brass texture{011}, S texture{123}, copper texture Cu{112}, cube texture{001} and Goss texture{011} is balanced, resulting in ears in 8 directions and low earing rate. Fe/Si of 1.8 possesses less content of Brass compared to Fe/Si of 3.2 ，and less earing rate; (2)The phase size of compound particles of Al(Fe,Mn,Si) in the second phase of 3104 aluminum-alloy canbody shouldn’t exceed 22μm, Lumpy compound particles will compromise the life of moulds.
