Book Description
Fracture toughness K sub Q, was studied as a function of microstructure for alloy no. 2, Ti-5.25Al-5.5V-0.9Fe-0.5Cu, at a y.s. of 180 Ksi (1241 MN/sq m, and for Ti-6Al-2Sn-4Zr-6Mo at y.s. of 160 Ksi (1100MN/sq m), with emphasis on alloy no. 2. For equiaxed alpha structures K sub Q initially decreased with increasing grain size (G.S.) and subsequently increased. Analysis of Widmanstatten plus grain boundary alpha data separated out the G.S. contribution which was attributed to increased plasticity when the G.S. became significantly large with respect to calculated plastic zone sizes. Attempts were made to calculate individual contributions of matrix and alpha to K sub Q. Experiments were conducted to correlate microstructure and mechanical properties for Ti-6-2-4-6.

Book Description
The effects of alpha/beta interface phase on room temperature tensile properties in Ti-6Al-4V having an equiaxed primary alpha microstructure have been studied systematically. Due to conditions under which it grows, manipulation of interface phase width results in alteration of the volume fraction of primary alpha in the alloy. Tensile yield strength and elongation were correlated to interface phase width and volume fraction primary alpha. The relative individual influence of each of these microstructural features on properties is not unambiguously clear, but evidence indicates that yield strength increases with increasing interface phase width when the interface phase exceeds about 2500 angstrom and elongation decreases with increasing interface phase width when the interface phase is less than about 2500 angstrom.

Book Description
Although a great deal of mechanical properties data on titanium alloys have appeared in the literature, no attempt has been made to relate the fine structures in beta titanium alloys to strength and fracture toughness. Therefore, strength and fracture toughness properties of B-120VCA--obtained through a variety of thermal and thermomechanical treatments--were related to fine structures by transmission electron microscopy, electron fractography, etc. Effects of (1) prior solution-treating temperatures, (2) cold working after solution treating, and (3) cold working both before and after solution treating were evaluated in terms of strength and fracture toughness, and parallel fine structure studies. The double cold-work treatment, without aging, produced ?t with a fracture toughness of 115 ksi?in. and may be promising for certain high-strength applications. Also short aging times produce unique combinations of strength and fracture toughness (?t ? 190 ksi, Kc ? 70 ksi?in. The kinetics of ?-> ? transformation were characterized and related to fracture toughness and strength properties. Precipitation of omega was suggested in the solution-annealed material during cooling to room temperature; further growth of this phase upon prolonged aging at 600 F was established. At 900 F, omega growth was limited, being replaced by alpha precipitation first in a discontinuous and later in a general dispersion.
