Исследование формирования твердых сплавов при взрывном прессовании смесей порошков карбида хрома с титаном

Abstract

The paper considers the investigations results ofthe microstructure and properties of Cr3C2‐based hardalloyby explosive compacting of chromium carbide and titanium powders without sintering. The effect of explosive loading modeson the porosity and hardness of the powder materials are presented. Using the methods of electron microscopy established that the chemical composition of the alloy didn’t change, and the elements redistribution between the phases didn’t occur. The features of the boundary surface formation of material components under shock‐wave treatment are discussed.

В работе исследована структура твердых сплавов, полученных прессованием взрывом смесей порошков карбида хрома Cr3C2ититана. Выявлено влияние режимов взрывного нагружения на пористость и твердость порошковых материалов. С использованием методов электронной микроскопии установлено, что химический состав компонентов сплава не претерпевает изменений, и перераспределение элементов между фазами не происходит. Исследованы особенности формирования межфазных поверхностей компонентов материала при ударно‐волновой обработке
