摘要： A method for producing a highly loaded, aqueous suspension having a pourable viscosity and containing from 20 to 50 volume percent colloidal ceramic or metal particles. A biologically produced polymer dispersant having a high density of carboxyl functional groups and an average molecular weight of at least 1,000 is solubilized in water in a quantity of less than 1.0 percent dry weight basis of particles. The ceramic or metal particles are then introduced to the solution, and agitated to form a substantially nonagglomerated suspension. The polymer dispersant may be produced by a bacterium grown in situ with the particles. A biologically produced polymer gelling agent that is miscible with the polymer dispersant may be admixed into the suspension, which is then maintained in a nongelled state while being supplied to a mold. The suspension is then exposed to a gel-triggering condition to form a gelled, sinterable article.

摘要： Aluminum base 7000 series alloys can have improved tensile properties when, after heat treatment and subsequent quenching, they are subjected to a three-step aging process comprising a first aging step at 190.degree.-230.degree. F., a second aging step at over 230.degree. F. and a third aging step at 315.degree.-380.degree. F. The improved process is particularly effective in improving the tensile properties of slowly quenched materials such as large extrusions or forgings.

摘要： Superplastic forming of aluminum work stock is improved by including therein about 0.05% to about 10% or 15% scandium together with up to 0.2 or 0.25% zirconium. In preferred practices, soluble elements such as magnesium are also included in the aluminum alloy. One or more of the elements from the group of scandium, yttrium, gadolinium, holminum, dysprosium, erbium, ytterbium, lutetium, and terbium, may be included in addition to or in lieu of scandium. Heat treatable aluminum alloys such as 7XXX alloys and 2XXX alloys can be made superplastic by including scandium and zirconium to provide very high strength in superplastically formed products.

摘要： There is disclosed a method for producing an aluminum alloy product and the resulting product having improved combinations of strength and corrosion resistance. The method includes providing an alloy consisting essentially of about 6-16% zinc, about 1.5-4.5% magnesium, about 1-3% cooper, one or more elements selected from zirconium, chromium, manganese, titanium, vanadium and hafnium, the total of said elements not exceeding about 1%, the balance aluminum and incidental impurities. The alloy is then solution heat treated; precipitation hardened to increase its strength to a level exceeding the as-solution heat treated strength level by at least about 30% of the difference between as-solution heat treated strength and peak strength; subjected to treatment at a sufficient temperature or temperatures for improving its corrosion resistance properties; and again precipitation hardened to raise its yield strength and produce a high strength, highly corrosion resistant alloy product.
