Fatigue life, fatigue crack propagation and fracture toughness study of 7075 aluminum alloy subjected to thermomechanical processing

Creator:: Lee, Moon H. (Moon Hee), 1949-
Abstract:: Due to its high strength/weight ratio, 7075 aluminum alloy has been widely used as an aerospace material. However, it has relatively low fatigue strength and low fracture toughness in the T6 condition. Thermomechanical processing, including pre-cyclic loading and stretching at high and ambient temperatures, has been investigated with the aim...

Percussion welding force, temperature and time relationships for welding 6061-T6 aluminum

Creator:: Eggers, Johannes Lyle
Abstract:: The force, temperature, and time relationships were investigated by using oscilloscope measurement techniques. Force was measured using a strain gage and the dynamic response recorded with a polaroid oscilloscope camera. Temperature was measured with a tungsten-rhenium thermocouple and recorded in the same manner. Residual stress measurements were made to determine...

A mechanism for filiform corrosion of aluminum

Creator:: Hoover, Steven Edward
Abstract:: A mechanism for filiform corrosion of aluminum is proposed based on experimental evidence and the known aqueous chemistry of the trivalent aluminum ion. Experimental methods utilized include autoradiographs with Cl³⁶; pH paper determination of the filiform head pH; activator concentration and activation period as they affect filiform growth. The pH...

Influence of cations on aluminum toxicity in wheat (Triticum aestivum Vill., Host)

Creator:: Erfan Ali, Shaikh Muhammad
Abstract:: The toxicity of aluminum (Al) to wheat (Triticum aestivum Host) was studied under controlled conditions using a technique designed to evaluate the recovery of root growth following a relatively brief (48 hour) exposure to nutrient solutions containing Al, When wheat seedlings were exposed to a minimum critical concentration of Al,...

Aluminum toxicity in the primary meristem of wheat roots

Creator:: Henning, Stanley John
Abstract:: The progression and consequences of aluminum toxicity were studied microscopically in the root tips of four wheat varieties representing different classes of Al tolerance. The root tips studied were collected from seedlings grown in nutrient solution cultures containing either sublethal or lethal Al treatments which were unique for each variety....

The time-concentration interaction of Al toxicity in wheat root meristems

Creator:: Rhue, Roy Dean
Abstract:: The time-concentration interaction of Al toxicity in the root meristems of Brevor wheat was studied using the L.D. 50 as a criteria for Al damage. The L.D. 50 represented a precise, well defined degree of biological damage which was easily reproduced under conditions where factors like temperature, pH, nutrient concentration,...

Influence of aluminum toxicity in intergeneric crosses of wheat and rye

Creator:: Lopez-Benitez, Alfonso
Abstract:: A technique previously designed to screen wheat cultivars and segregating populations for tolerance to Aluminum utilizing nutrient solutions in growth chambers was found to be efficient in differentiating among cultivars of wheat, rye, and triticale for tolerance to Al under greenhouse conditions. A 5°C increase in temperature, from 25°C to...

A reaction rate determination of aluminum with a microcomputer-based spectrofluorometer

Creator:: Campi, Gregory Louis
Abstract:: The development and optimization of a fluorometric reaction rate method for the determination of aluminum is described. Modifications to existing instrumentation permit automatic monitoring and reporting of measurement conditions. Automatic correction of measured analytical signals is provided if monitored parameters deviate from optimum values. A computer controlled standard addition procedure...
