Heterogeneous alloys have been classified behind influence of temperature on the strengthened properties of inclusions and matrix. The temperature flashes model is specified. The influence of structure of heterogeneous alloys (phosphorous cast-irons, pseudo-alloys on the basis of systems Al-Pb, Al-Sn) on friction processes have been investigated. The properties and features of new synthesized alloys have been investigated. Product Description popup.authors popup.nrat_date 2020-04-02 Close
