INFLUENCE OF AGING AND STRAIN ON THE STRUCTURE AND MECHANICAL PROPERTIES OF CHROMIUM-ZIRCONIUM BRONZE

DOI: 10.17804/2410-9908.2015.5.099-108

The influence of aging and deformation by dynamic channel-angular pressing (DCAP) on the change of the structure and mechanical properties of Cu-0.14%Cr-0.04%Zr low-alloy chromium-zirconium bronze has been studied. It is shown that, under DCAP and subsequent aging, the studied bronze suffers the decomposition of the alpha-solid solution accompanied by the precipitation of nanosized particles of chromium and the copper-zirconium phase. This hardens the bronze and increases its thermal stability. A substantial increase in the mechanical properties of the bronze after DCAP and subsequent aging has been found. Thus, ultimate strength is increased 2.8 times and yield stress is increased 5.1 times as compared with the initial hardened condition, satisfactory plasticity being maintained.

Keywords: chromium-zirconium bronze, high-strain-rate deformation, aging, submicrocrystalline structures, na-nosized particles, yield stress, ultimate strength, microhardness

ВЛИЯНИЕ СТАРЕНИЯ И ДЕФОРМАЦИИ НА СТРУКТУРУ И МЕХАНИЧЕСКИЕ СВОЙСТВА ХРОМОЦИРКОНИЕВОЙ БРОНЗЫ

Исследовано влияние старения и деформации методом динамического канально-углового прессования (ДКУП) на изменения структуры и механических свойств низколегированной хромоциркониевой бронзы Cu-0,14%Cr-0,04%Zr. Показано, что при ДКУП и последующем старении в исследуемой бронзе происходит распад a-твердого раствора с выделением наноразмерных частиц хрома и медноциркониевой фазы. Это приводит к упрочнению бронзы и повышению ее термической стабильности. Установлено существенное повышение механических свойств исследуемой бронзы после ДКУП и последующего старения. Так, предел прочности увеличивается в 2,8 раза, предел текучести – в 5,1 раза, по сравнению с исходным закаленным состоянием, при сохранении удовлетворительной пластичности.

Ключевые слова: хромоциркониевая бронза, высокоскоростная деформация, старение, субмикрокристалличе-ские структуры, наноразмерные частицы, предел текучести, предел прочности, микро-твердость
