Effect of Environment on the Cracks Behavior in TA6V Alloy

Wednesday, January 9th, 2008

To get more information on the fatigue behavior of Ti-alloys, the growth of long cracks and of physically short bidimensional cracks has been studied on a TA6V alloy. This article presents some results obtained on the influence of the crack wake on the propagation of fatigue cracks in specimens tested in ...

Chemical and Mechanical Properties of Titanium and Its Alloys

Friday, January 4th, 2008

Titanium, like other elements, is a composite of several isotopes, which range in atomic weight from 46 to 50. The proportions of these isotopes have been computed from spectrographic analysis. Mathematical calculations employing the proportions and mass numbers have assigned titanium a mean atomic weight of 47.88. Unalloyed titanium may have ...

Joining Titanium

Friday, January 4th, 2008

A great tonnage of fabricated metal components requires joining in some form or other. These joining methods may include welding, brazing, soldering, riveting, or bolting. Titanium, therefore, in order to be a useful structural metal for such applications as aircraft, bridges, pipes, tanks, vehicles, and ships, must have the ability ...

Superplastic Deformation of Two-Phase Ti-6Al-4V Alloy

Friday, January 4th, 2008

Superplastic materials are polycrystalline solids which have the ability to undergo large strains prior to failure. Since manufacturing costs and the weight of airframe structures can be reduced significantly through superplastic forming technology, considerable efforts have been devoted during the past three decades to the investigation of the superplastic deformation behavior ...

Physical Properties of Titanium and Its Alloys

Tuesday, January 1st, 2008

Titanium is lightweight, strong, corrosion resistant and abundant in nature. Titanium and its alloys possess tensile strengths from 30,000 psi to 200,000 psi (210-1380 MPa), which are equivalent to those strengths found in most of alloy steels. The density of titanium is only 56 percent that of steel, and its ...

Titanium exports dip on cuts by Belgium, UK

Friday, November 16th, 2007

Shipments totaled 1,841 short tons in September, down from 1,887 tons in August, according to figures from the U.S. Commerce Department. Buyers in the United Kingdom trimmed their intake by more than 300 tons in September, taking in 765 tons that month vs. 1,079 tons in August. The Belgians trimmed their ...

Titanium piston for malleovestibulopexy

Friday, November 16th, 2007

Stapes prostheses are used to bridge the fixated stapes. Normally, this is achieved using the long process of incus, but the stapes can also be reconstructed from the malleus handle (malleovestibulopexy). In that case, an extra-long prosthesis creates a direct connection between the malleus and the inner ear. In the ...

Titanium exports surge on ferroalloy demand

Friday, November 16th, 2007

U.S. exports rose to 4,163 short tons from 2,317 tons in February, according to the latest figures from the U.S. Commerce Department, although first-quarter shipments of 8,004 tons were down 41.5 percent from 13,679 tons in the same period last year. The Commerce figures for February 2004 included an 11,493-ton ...

Driver con-Fusion? After a slow start, composite-titanium drivers are making news

Friday, November 16th, 2007

No one will dispute that the composite-titanium driver has yet to sweep the fancy of the U.S. golf market. But the key word might be "yet." Though consumers are still trying to understand the benefits of marrying some form of graphite in the body of a driver with a thin-titanium ...

Taurus Titanium Tracker: a handy little “niche gun,” this useful .45 ACP Revolver is a surprisingly good value

Saturday, October 13th, 2007

The five-shot, large-bore Tracker revolvers in 2" to 4" barrel length have proven to be surprisingly popular for Taurus in big bore calibers. The company has recently produced a limited run in .45 ACP in the Total Titanium series. Lockwork and screws are case-hardened chromemoly ordnance steel, and the ...
