Development of lean titaniumalloyed aluminium alloy for electrotechnical purposes
Journal Title: Восточно-Европейский журнал передовых технологий - Year 2018, Vol 1, Issue 12
Abstract
<p>The influence of titanium amount and pouring temperature on the structure and properties of lean-alloyed alloy was explored. It was determined that lean titanium-alloyed aluminum alloys have better mechanical and electrical properties, which is explained by formation of heat-resistant dispersoids in solid solution. It was found that an increase in the amount of titanium by more than 0.5–0.6 % has a negative influence on electrical properties of the aluminium-based alloy. It was revealed that formation of four types of phases in complex-alloyed Fe and Si alloys contribute to preservation of tensile strength.</p>The results of comparative studies of ingots and wires from experimental and mass-produced alloys were given. Results of experimental research on determining the modes and parameters of deformation and thermal treatment and their influence on mechanical and electrical properties of aluminum alloys were presented. They made it possible to develop the technology of production of lean titanium-alloyed aluminium-based alloy and rolling electrical products from it. During its implementation it was found that aluminum ingots, cold-treated sheets and wires, retain the necessary strength and minimal specific electrical resistance at high enough temperatures. A positive effect of cold deformation and intermediate annealing on formation of the rational structure and a good combination of electrical and mechanical properties of the products was revealed
