The project aim is an extensive research on the employment of mechanochemical synthetic approach for the production of metal matrix nanocomposite powders based on Mo and reinforced with rare-earths oxide phases for reduction of ductile-to-brittle transition temperature and improvement of high temperature oxidation behaviour. This aim will be achieved by applying solid-solid (ex-situ) and liquid-solid (in-situ) composite powder synthetic strategies, utilizing the high energy kinetic milling, reactive kinetic milling, mechanochemistry and chemistry. In the ex-situ study the ultrafine powders of rare-earths oxide phases (mainly based on La, Gd, and Ce oxides and zirconates) will be synthetized via sol-gel techniques or mechanochemical syntheses, and in a secondary phase they will be milled with the commercially available Mo metal powders using high-energy ball milling. The role of milled powder chemistry as well as the effects of technological parameters, i.e. milling speed, milling time, milling temperature, milling atmosphere, milling media, ball-to-powder ratio and process control agents on reduction of powder particle size, rare-earth oxide or zirconates particle distribution at the metal grain boundaries, and its influence on alloying or phase transformation will be investigated. The in-situ study will focus on processing, reaction mechanisms and technological parameters with the aim to obtain composite reinforcement with rare-earth oxide/zirconate phases directly from the reagents mixed with Mo metal powders in high-energy ball mill. Both powders, produced by ex-situ and in-situ methods will be studied by the means of available techniques widely used in materials science.
