13DV10049, METHOD FOR DEVELOPING ENHANCED TEXTURE IN TITANIUM ALLOYS, and ARTICLES MADE THEREBY ABSTRACT OF THE DISCLOSURE, Enhanced crystallographic texture is developed in an alpha or alpha-beta titanium alloy having a dispersion of particles therein, by heating the alloy to essentially the all beta phase range and mechanically hot working the alloy in this range. The mechanical working is preferably accomplished by extrusion, rolling, or forging. The particles are stable during working, and prevent the formation of random texture in recrystallized beta phase grains at the working temperature. The particles are preferably oxides formed from rare earth elements such as erbium or yttrium, …

Why it's free to use
- Filed June 21, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 21, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 21, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
