摘要： This invention relates to the synthesis of a new generation of metastable aluminum-titanium (Al—Ti) alloys and the process of making them. The preparation method used is a combination process incorporating the advantages of conventional casting and spray techniques. The process is a low cost process. The aluminum-titanium materials made in this invention contain titanium in both the reacted and unreacted form. The results were confirmed using microstructural and x-ray diffraction studies. The presence of phases clearly indicate the metastable nature of these materials in accordance with the equilibrium phase diagram established for Al—Ti system. The Al—Ti materials can be made in the dimensions suitable for structural applications at ambient and elevated temperatures and as control materials for synthesis of more dilute equilibrium Al—Ti materials using conventional techniques such as casting.

摘要： A free-machining alloy is disclosed containing bismuth and indium. The free-machining constituents act as low melting point compounds for machining and are specially adapted for use in aluminum alloys such as AA6000 series and AA 2000 series alloys. The bismuth and indium are effective replacements for the lead and bismuth addition used previously to improve machinability while providing a high impact energy free machining alloy.

摘要： The high-purity aluminum sputter target is at least 99.999 weight percent aluminum and has a grain structure. The grain structure is at least 99 percent recrystallized and has a grain size of less than 200 &mgr;m. The method forms high-purity aluminum sputter targets by first cooling a high-purity target blank to a temperature of less than −50° C. and then deforming the cooled high-purity target blank introduces intense strain into the high-purity target. After deforming, recrystallizing the grains at a temperature below 200° C. forms a target blank having at least 99 percent recrystallized grains. Finally, finishing at a low temperature sufficient to maintain the fine grain size of the high-purity target blank forms a finished sputter target.

摘要： A typical air bridge is an aluminum conductor suspended across an air-filled cavity to connect two components of an integrated circuit, two transistors for example. The air-filled cavity has a low dielectric constant which reduces cross-talk between neighboring conductors and improves speed and efficiency of the integrated circuit. However, current air bridges must be kept short because typical aluminum conductors sag too much. Accordingly, one embodiment of the invention forms air-bridge conductors from an aluminum-beryllium alloy, which enhances stiffness and ultimately provides a 40-percent improvement in air-bridge lengths.
