This report results from a contract tasking G.V Kurdyumov Institute for Metal Physics, National Academy of Sciences of Ukraine as follows: Proposed project is dedicated to development of physical background of Local Rapid Heat Treatment (LRHT) of titanium parts, which allowed to improve a balance of its mechanical properties (tensile and fatigue). Employing three different commercial titanium alloys as program material research work will consist of two main efforts. The ...
This report results from a contract tasking Institute for Metal Physics, NAS of Ukraine as follows: The need for computer simulation of recrystallization and grain growth is driven by necessity to make quantitative predictions of the microstructure and properties of thermo mechanically processed materials. There are several approaches to modeling the recrystallization phenomenon: vertex models, phase field models, Monte Carlo (MC) models and Cellular automata (CA) models. For our opinion, ...
This report results from a contract tasking Institute for Metal Physics, NAS of Ukraine as follows: The demands on materials set by aerospace and aircraft manufacturers include the development of alloys possessing high strength-to-weight ratios and capable to withstand high temperature exposures during service. One of the promising classes of materials which may meet these requirements are Al-based alloys with nanocomposite structures formed by partial crystallization of amorphous precursors the ...
This report results from a contract tasking Institute for Metal Physics as follows: This project will conduct a fundamental study of Ni-Mn-Ga-X alloys exhibiting large and stable values of magnetic-field-induced strain at temperatures above 320 K. The objective is to establish the factors determining the values and stability of magnetic shape memory behavior in order to feed the design of a new class of magnetic shape memory actuators and sensors. ...
