The use of a combined additive consisting of silica-containing additives“F”(thinning)and“S”(accelerating castable hardening)instead of the previously used silica-containing additive“A”and a mixture of dispersing additives based on polyethylene glycol in low-cement silicon carbide castable allows to improve the castable workability by increasing(in 5.4 times)the flowability of a freshly prepared castable,and increase by 1.2 and 1.1 times the cold crushing strength of heat-treated at temperatures of 110 and 1580°C,respectively,castable samples from low-cement silicon carbide castable with practically equal values of open porosity(15.8%and 16.0%).The petrographic studies of the castable sample microstructure after firing at a temperature of 1580°C showed that the investigated silica-containing additives“F”and“S”contribute to the denser and more uniform structure *** a result of the carried out research,the manufacturing technology of a low-cement silicon carbide castable was improved,of which the production was mastered at JSC“URIR named after ***”.

Transactions of Nonferrous Metals Society of China 2014年第5期24卷 1365-1371页

Influence of severe cold deformation of titanium alloy Ti-1.5%A1-6.8%Mo-4.5%Fe in metastable β condition on the evolution of phase composition, microstructure, and tensile properties during continuous rapid heating was studied. As-deformed alloy was characterized by quasi-amorphous single-phase β condition with an abnormal temperature dependence of electric resistance that was normalized after 48 h exposure at room temperature as a result of isothermal ω phase precipitation. Subsequent rapid heating with a rate of 5 ℃/s caused recovery and recrystallization. Tensile properties of the alloy after different treatments were determined and discussed.

The Ni_3B phase was formed when boron (0.5 at. pct B) was added to the intermetallic of sto- ichiometric and off-stoichiometric (Ni-24 at. pct Al) compounds. In the alloy of stoichiometric composition the particles of Ni_3B phase has the size around 0.1μm and is located on the grain boundary of the main phase. The decreasing of concentrations of Al in the ofF-stoichiometric alloy leads to increase in the degree of the long-range order parameter, increasing the concen- trations of boron in the solid solution and decreasing its localization on the grain boundary. Microalloying of boron leads to increasing in the fraction of grain monodomains with disloca- tions up to 0.7 in the alloy of the off-stoichiometric composition and up to 1 in the alloy of the stoichiometric composition. It was established the correlation between the degree of the concentration inhomogeneity, average density of the dislocations and the average long range-order parameter.

The Anaple project is an ongoing effort to provide an object oriented software environment for data analysis in HENP experiments,A range of commercial and public domain libraries is used to cover basic functionalities;on top of these libraries a set of HENP-sepcific C++ class libraries for histogram management fitting,plotting and ntuple-like data analysis has been developed .In order to comply with the user requireements for a command-line driven tool,we have chosen to use a scripting language(Python)as the fromt-ent for a data analysis *** loose coupling provided by the consequent use of (AIDA compliant)Abstract Interfaces for each component in combination with the use of shared libraries for their implementation provies an easy integration of existing libraries into modern scipting languages thus allowing for rapid application *** integration is simplified even further suing a specialised toolkit(SWIG)to create" shadow Classes"for the Python language,which map the definitions of the Abstract Interfaces almost at a one-to-one *** paper will give an overview of the architecture and design choices and will present the current status and future developments of the project.
