Relationship Between Structure and Properties of the Large-Size Billet of Titanium Alloy PT-7M

“…The X-rays diffraction scans presented on 5873), which is typical for alloys with aluminum [9]. It should be noted the line (002) has maximum intensity on diffractograms of longitudinal section (Fig.…”

Structure and Hardness Variations Through Section of Hot-Forged Pipe Billet from PT-1M Alloy

“…The lattice parameters of the α-phase, determined after shooting in different sections, are almost the same: a = 0.2948 ± 0.0001 nm, c = 0.4682 ± 0.0001 nm, c/a = 1.588. The obtained values of the «c/a» parameter of the α-phase are slightly higher than of pure titanium (1.587) due to the aluminum alloying[8].…”

Structure and Properties of the Billet of PT-1M Alloy after Expanding

“…3). Thus higher values of the elastic modulus in the longitudinal section are determined by a large number of grains in this section with the orientations 101 and 002, that is, along the "c"-direction of the HCP-lattice of -phase, which is characterized by the maximum value of the elastic modulus [10]. In the cross section, the high modulus orientations 101 and 002 are generally weaker (Fig.…”

“…In the cross section, the high modulus orientations 101 and 002 are generally weaker (Fig. 3) and the intensity of the lower modulus orientations 100 is higher [10]. This result to a lower level of the elastic modulus than in the longitudinal section.…”
