Dispersion Strengthened Titanium Alloys

Finley dispersed nano-particles of oxides can be successfully used in the strengthening of titanium alloys due to their hardness, stability and insolubility in the base-metal.
Other dispersoids can also be used such a ceramics but the most important aspect is for them to be thermodynamically stable, homogeneously distributed in the metal matrix and of nanometric size. Continue reading

Boronization of Titanium Alloys

Boronizing is a surface treatment by which boron atoms are diffused into the surface of the metal in quantities exceeding the solubility limit.
Hardness is improved and thus wear resistance increased as well as a number of other advantages such as corrosion and oxidization resistance. Continue reading

Electro-Slag Welding (ESW) of Titanium Alloys: Part Two

Due to its well-known superior strength to weight ratios, titanium has become a more and more critical material choice in aerospace applications which require heavy loading.
Due to titanium’s high chemical activity welding can be a real challenge but to overcome this, new technologies are being developed which uses the slag pool and argon to shield the weld site from interstitial element contamination. Continue reading

Brazing of Titanium and Titanium Alloys: Part One

Titanium and its alloys are well known for their high-strength and corrosion resistant properties but one distinct disadvantage is the challenges associated with bonding them with other materials. Brazing could provide a solution to these challenges since only the filler material is melted in the process therefore aiding dissimilar material bonding due to little or no effect on the two main subject materials. Continue reading
