摘要:
Generally, Ti in solution damages the electrical conductivity of aluminum, so the less the better. However, during boron treatment process trace Ti can promote the precipitation of transition metal elements in forms of doped borides, thus improving the electrical conductivity of aluminum. With conventional boron treatment, the efficiency is 77.7% and electrical conductivity of AA1070Al is 64.6% IACS. However, with Ti assistant, owing to the compositional evolution of borides, the efficiency can reach 93.3% and electrical conductivity of AA1070Al is increased to 65.3% IACS, which is much higher than that with conventional boron treatment. Based on this, a novel composite boron treatment technology is proposed and a schematic diagram is built to analyze the complex reaction mechanism of boron treatment. (C) 2017 Elsevier B.V.
