Book Description
The effects of microstructure and temperature on tensile and fracture behavior were explored for the titanium aluminide alloy Ti-25Al-lONb-3V-lMo (atomic percent). Three microstructures were selected for this study in an attempt to determine the role of the individual microstructural constituents. the three microstructures studied were an alpha-2 + beta processed microstructure with a fine Widmanstaetten microstructure, a beta processed microstructure with a fine Widmanstaetten microstructure, and a beta processed microstructure with a coarse Widmanstaetten microstructure. Tensile testing of both round and flat specimens was conducted in vacuum at elevated temperature and in air at room and elevated temperatures. Extensive fractography and specimen sectioning were used to study tensile deformation and the effects of environment on this alloy. Room temperature fracture toughness testing using compact tension specimens was conducted. Elevated temperature toughness testing was performed using J-bend bar specimens in an air environment. Again, extensive fractography and specimen sectioning were used to study the elevated temperature toughening mechanisms of this alloy ... Titanium, Titanium aluminide, Intermetallic, Fracture toughness, Tensile behavior, Fractography environmental interaction.

The Effects of Deformation Mode and Microstructure Fracture-Related Properties of Ti Alloys
Author: J. E. Allison

Languages : en
Pages : 20
Book Description
Fatigue crack growth has been studied in two binary Ti-Al alloys, an 8 wt.% Al and a 4 wt.% Al alloy. It has been found that the crack growth rate is faster than in the 4% Al alloy. The principal difference between the alloys is that the higher Al alloy exhibits planar slip. The effect of this planar slip character is to cause a more irregular crack path. This increase in crack path irregularity causes roughness-induced closure. Back face strain measurements have been used to measure the variation in closure and to calculate an effective delta K. It lso has been shown that the crack growth rates for the two alloys coincide if the variations in closure are taken into account. Elevated temperature crack growth experiments have also been conducted and oxide-induced closure effects have been found in this case. This type of closure also affects the crack growth rate. Finally, crack growth experiments at high mean stress have been conducted and it has been found that the closure effects disappear. The implications of this work on the selection of materials for fatigue crack growth limited applications is discussed. (Author).
