Surface observation and electrochemical measurements were carried out to clarify the influence of acetic acid on corrosion behaviors of industrially pure aluminum alloy 1100. The consideration of the potential-pH-pOAc diagram and polarization analysis reveal that coexistence of citric acid and chloride ions will severely pitting-attack aluminum alloy 1100.

The two-step aging behaviors of various Al–Mg–Si alloy extrusions have been studied mainly by tensile testing, differential scanning calorimetric analysis (DSC) and electrical resistance measurements. The natural aging at 5°C, 20°C and 40°C for 86.4 ks has a beneficial effect on the strength after artificial aging of the low Mg2Si containing alloys. On the other hand, the natural aging has a negative effect on the strength after artificial aging of the high Mg2Si containing alloys. The β″ peak on the DSC curve shifts to a higher temperature with natural aging for the high Mg2Si alloy. However, no β″ peak was found for the low Mg2Si alloy. This suggests that there is no negative effect dominated by β″ phase for the lower Mg2Si alloys.

Description is given of the properties of aluminium foil as well as of its present use for packaging, insulation, decoration and capacitor with some examples.With our increasing knowledge of the properties of aluminium foil the use of aluminium foil has been greatly accelerated, and the improvement of laboratorial methods and manufacturing technique concerning embossing, printing and lacquering has made new applications possible.With the downward trend in prices and increasing interests of customers aluminium foil seems to to have the bright future finding new fields for more applications.

In Japan Air Self-Defense Force, serious corrosion problems were encountered, regarding to the presence of the microorganisms in JP-4 fuel. Fuel was dripping from a tank in jet fuel aircraft. Microorganisms were cultured after being isolated from the JP-4 fuel underground storage tank, tank-lorry, water separator, and aircraft fuel tank. The effects of microbiological corrosion were examined on the specimens of 61-S aluminum alloy which was used in aircraft fuel tanks.The results were as follows:(1) Seventeen sorts of bacteria and three sorts of fungi were found to be bred by the utilization of JP-4 as nutritious element.(2) After culturing for 140 days, the surfaces of some aluminum specimens were covered with brown powdery blisters caused by the growth of microorganisms and other contaminations.(3) Severe corrosion pits were made on aluminum specimens, on which Micrococcus caseolyticus, Comamonas, and Vibrio faecalis were cultured.(4) It was observed that the surface of aluminum alloy specimens was covered with mycelium mats of Cladosporium resinae and tremendous corrosion existed under the mats.As the results, it is concluded that the preparation of filter-separator equipment such as ultrafine filter will be effective for the purpose of perfect removal of microorganisms from aircraft fuel.

Binary titanium alloys containing Nb or Ta, which are allergy-free and non-toxicity elements, were fabricated, and then the possibility of their application to various music instruments made of brass was investigated by the evaluation of corrosion characteristics, elastic modulus-density ratio (E/ρ), resonance frequency (f) and internal friction (Q−1) . The practical models of the mouthpieces of the trumpets made of the binary titanium alloys were also fabricated by precision casting method in order to compare directly with the sound characteristics of those made of brass and commercially pure Ti. The critical current density for the passivation of the Ti–Nb and Ti–Ta system alloys is approximately 40% lower than that of brass and nearly equal to or a little higher than that of commercially pure Ti. The Q−1 of the Ti–Nb and Ti–Ta system alloys with α″ phase drastically increase. The E/ρ and f of the Ti–Nb and Ti–Ta system alloys exhibit a positive relationship. The sound characteristics of practical mouthpieces of trumpets for a bass instrument can be controlled by changing the E/ρ and f of the alloys.

Aluminum corrosion induced by microbial contamination of jet fuel has become one of the most important troubles. The object of the present work is to study the corrosion of aluminum caused by the growth of fungi isolated from jet fuel system. Of the fungi isolated, Cladosporium resinae appeared to be the most predominant. Many kinds of filamentous fungi were obtained from slime of jet fuel, water layer of storage tank, and sludges on stringer and lower panel of integral fuel tank of YS-11 jet planeResults obtained were as follows.(1) After 330 day incubation, exfoliation and corrosion occurred with small blisters on the surface of aluminum alloy, 6061 specimen.(2) The cross section of the 6061 specimen indicated that the corrosion pits by Cladosporium resinae were extensively evident thoughout the aluminum body.(3) The specimens of high purity aluminum (1099 and 1100), anodized aluminum, and aluminum alloy 5052 were severely damaged by the attack of the fungus.(4) An extruded bar of 1100 was also attacked by Cladosporium resinae. Corrosion pits began to develop after 30 day culture of the fungus.(5) Large amounts of sludge deposits were found on the stringer and lower skin panel of the integral tank of YS-11 jet plane. Widespread corrosions were found in the area covered by the growth of the fungus.(6) Discussions were also made over the development of tests for the effects of protective coatings.
