Crystalline characteristics of alpha precipitates in Ti–15V–3Sn–3Al–3Cr alloy

Microstructure Evolution and Microhardness Analysis of Metastable Beta Titanium Alloy Ti-15V-3Cr-3Al-3Sn Consolidated Using Equal-Channel Angular Pressing from Machining Chips

“…The corresponding SAD pattern shows the zone axis of [1 % 10]β. An identical SAD pattern has been also reported in the reference [30] , and the calibrated pattern is illustrated in Fig. 12(c).…”

“…Moreover, the formation of α phase is restrained by the variant selections, and hence acicular shape. As explicated by Guo et al [30] , the habit plane of α precipitates was {111}β and the orientation relationships between α precipitates and β matrix were <112 % 0>α ∥ <111>β and {0001}α ∥ {110}β. These relationships were also confirmed by the experimental results obtained in hot-drawn Ti-15Nb-2Mo-2Zr-1Sn [31] .…”

“…It can be found that the diffraction spots of variants (100)2α and (100)12α spread to barlike pattern along the [111]β and [11 1 % ]β directions, respectively. Based on the investigation conducted by Guo et al [30] , the α variant 2 and α variant 12 lie on the planes of (111)β and (111 % )β, respectively. SAD pattern taken from the β grain in (a), (c) calibrated SAD pattern of (b) [30] .…”

Determination of α lamellae orientation in a β-Ti alloy using electron backscatter diffraction

“…The � lath spatial orientation has been investigated for several alloy systems. While some research determined that the habit plane of an � lamella is (approximately) parallel to one of the {111} � planes (Furuhara et al, 1991(Furuhara et al, , 1998Guo et al, 2010;Ohmori et al, 1998), other work has reported the habit plane close to f11 11 13g � (Shi et al, 2012;Furuhara et al, 1996;Zherebtsov et al, 2010;Bhattacharyya et al, 2007), or {334} for an h.c.p. � 0 martensite (Qiu et al, 2014).…”
