Methods for the manufacture of the above-mentioned titanium alloy for use in combustion engine exhaust systems are disclosed herein. An exemplary method of the disclosed subject matter for the manufacture of titanium alloy for use in a high temperature and high stress environment includes performing a first heat treatment of the titanium alloy at a first temperature, rolling the titanium alloy to a desired thickness, performing a second heat treatment of the titanium alloy at a second temperature, and performing a third heat treatment of the titanium alloy at a third temperature. In some embodiments, the first temperature is selected such that recrystallization and softening of the titanium alloy is optimized without substantial coarsening of second phase particles and can be approximately 1500-1600&#xb0; F. In some embodiments, the rolling of the titanium alloy reduces the thickness of the titanium alloy by at least than 65%.

Methods for the manufacture of a titanium alloy for use in combustion engine exhaust systems

Rain gutter cover

An oxidation resistant, high strength titanium alloy, particularly adapted for use in the manufacture of automotive exhaust system components and other applications requiring oxidation resistance and strength at elevated temperatures. The alloy comprises, in weight percent, iron less than 0.5, or 0.2 to less than 0.5%, oxygen 0.02 to less than 0.15%, silicon 0.15 to 0.6%, and balance titanium. Optional alloying elements are Al, Nb, V, Mo, Sn, Zr, Ni, Cr and Ta, with a total content of less than 1.5.

Titanium alloy and automotive exhaust systems thereof

A titanium alloy containing carbon with and without addition of silicon exhibiting improved corrosion resistance and mechanical strength as compared to commercially pure ASTM grade 2 titanium or PGM-alloyed ASTM grade 7 titanium.

Titanium alloy having improved corrosion resistance and strength

The leaf guard for gutters is an elongated sheet of enamel coated aluminum adapted to fit over the rain gutter on a house in a manner that directs water flow from the roof into the gutter while preventing leaves and other debris from entering the gutter. In a first embodiment, the guard is formed into a planar section that is secured to a roof, a curved nose section extending from the planar section, a trough under the curved section and a cornered lip extending from the trough to secure the device to the outer rim of a gutter. In a second embodiment, the guard is formed into a planar section, an inwardly bent connection section that is connected to the inner rim of a gutter, and a curved nose section that hangs over the outer rim of the gutter. The guard also has rows of elongated slits in the planar section that permit some water to drip through to prevent bees and other insects from nesting beneath the device. The device is bendable such that the slope of the planar section can be changed to meet the varying needs.

Leaf guard for gutters

High strength alpha-beta alloy comprising essentially Al: 4.5-5.5%, V: 3.0-5.0%, Mo: 0.3-1.8%, Fe: 0.2-1.2%, oxygen 0.12-0.25% Ti: balance. All other incidental elements should be less than 0.1% for each element and less than 0.5% in total. The alloy possesses improved machinability and ballistic performance compared to Ti-6Al-4V.
