If the approach of the bodies Do is unknown, and the load P is given, then in order to determine Do one should add to Eqs. (2.31) and (2.32) the equilibrium condition (2.33) When we study the contact interaction of a system of smooth axially symmetric punches with the elastic half-space, the radius of each contact spot a* is the unknown value.

Titanium is "tough" for lack of a better descriptor. I have formed titanium by heating in the forge, and going into specialty press dies....but even that requires a ton of work....the Ti work hardens/cools so rapidly that the dies have to be heated above 350F, to even get a single "press" in, or the titanium simply breaks.

Figure 3 depicts the effects of media size on grinding times. From this plot, it is shown that a target fineness of 80% < 2 microns is normally achieved in 315 minutes of recirculation milling with 1.0 to 1.4 mm grinding media. By reducing the media diameter to 0.6 to 0.8 mm after 90 minutes, the target grind is achieved in only 150 minutes.
