Wafer curvature was used to study the thermal–mechanical behavior of 1-μm Cu thin films capped with a 100-nm-thick Si3N4 layer. These films were grown with either a Ta or a Si3N4 underlayer. Films on Si3N4 that were exposed to oxygen at the film/capping layer interface or at the center of the copper layer exhibited Bauschinger-like yielding at low stress. Stacks deposited under continuous vacuum, with a Ta underlayer, with carbon exposure at the upper surface of the copper film, or with oxygen exposure of only the underlayer did not demonstrate the anomalous yielding. Preferential diffusion of oxygen into copper grain boundaries or interfaces is the likely cause of the early yield behavior. Possible mechanisms include an increase in interface adhesion due to the presence of oxygen in solution and diffusion-induced dislocation glide as an additional driving force for dislocation motion at low applied stress.

Two Stages

The CSIRO is developing the TIRO™ process for the continuous direct production of titanium powder. The process comprises two stages. The first stage is a fluidised bed reactor (FBR) in which TiCl4 is reacted with magnesium powder to form solid magnesium chloride particles about 350 µm in diameter in which micron sized titanium particles are dispersed. The second stage is a continuous vacuum distillation operation where the titanium is separated from the magnesium chloride and sintered to form a friable “biscuit”. The biscuit comprises porous titanium spheres about 250 µm in diameter which can be liberated by very light grinding. The overall process has a throughput of 0.2 kg/h Ti, limited by the vacuum distillation unit and is being scaled up. The process has generated Ti powder with ≤0.25 wt% O and < 200 ppm Cl and meets CP2 specifications. Ring grinding the vacuum distilled product for short periods reduced the particle size, however longer grinding times caused agglomeration of the particles. Ring grinding in air resulted in a large increase in oxygen concentration

Rigid Design

During ecological researches and monitoring of the natural aquatic environment it is very often necessary to carry out filtration of water large volumes for extraction on filters the weighed components, and for subsequent analysis of mineral and organic suspension’s structure. The installations applied now for vacuum filtration have a number of essential restrictions. The most important deficiency of existing installations for vacuum filtration is the use of a leak-tight receiver with rigid design. At intensive filtration such receiver has to have a large volume that limits filtration installation’s possibilities for transportation and afield operation. Need of a vacuum pump’s protection against a filtrate intrusion demands constant monitoring for receiver filling at the large filtration volume. During receiver filling the filtration process needs to be interrupted for filtrate removal from the receiver, but sometimes such interruption significantly complicates the filtration process. In this paper is described the developed new mobile installation for continuous vacuum filtration based on a closed cycle water-jet pump for vacuum generation. The proposed installation for vacuum filtration of natural water’s weighed components allows carry out filtration of water large volumes in the continuous mode. The installation hasn’t a leak-tight vacuum receiver so that it has small dimensions.
