6. Treatments to specifically enhance certain working properties
Of course, like all metals, titanium alloys are subject to the hardness/toughness trade-off. However, the compromise can be more or less to the advantage of one property or another, depending on the treatment used, as the following examples show.
6.1 Tenacity
This is the first criterion to be taken into account, as it evolves, overall, inversely to strength. Thus, the stress intensity factor K lc can be related to the breaking load (figure 32 ).
