摘要
The main types of microstructure are (1) lamellar – formed after slow cooling when deforma‐ tion or heat treatment takes place at a temperature in the single-phase β-field above the socalled beta-transus temperature Tβ (at which the α+β→β transformation takes place), consisting of colonies of hexagonal close packed (hcp) α-phase lamellae within large body centered cubic (bcc) β-phase grains of several hundred microns in diameter, and (2) equiaxed – formed after deformation in the two-phase α+β field (i.e., below Tβ), consisting of globular α-phase dispersed in β-phase matrix [7-8].
