铝基合金

In this study, copper alloy adding Ti-Zr and Al-Zr was the target and made the cupper alloy ingots by vacuum arc remelter. After rolling and heat treatment, the two-inch round target was cut by wire electrical discharge machining. DC sputtering deposited cupper alloy thin films on silicon base materials and optical glasses to discuss the thin film microstructures、compositions、practical performances and optical characteristics.

It is possible to produce low-titanium aluminum alloy directly. Three months of periods of industrial test for production low-titanium aluminum alloy was conducted using the 80kA prebake electrolysis cells. The test results showed that the electrolysis cell can work stably, and the effect of TiO2 added into electrolyte on electrolytic process parameters, current efficiency, consumes of materials and energyare trifling. The titanium content in alloys is stable and the absorbility of Ti is high. The microstructure of electrolytic low-titanium aluminum alloy is homogeneous. The grain refinement effect is excellent comparing with that of alloys added titanium by melting Al-Ti master alloys and both alloys have the same grain refinement trend.
