摘要: A 10-layer Ti–10Mo–1Fe/Ti–10Mo–3Fe alternating stack material was manufactured by hot-roll bonding and heat treatment. The interfaces between layers could not be detected except for transition region in Fe concentration. However, the prevented {3 3 2} twinning Ti–10Mo–1Fe from expanding throughout Ti–10Mo–3Fe which deformed dislocation slips despite having same crystallographic character. artificially multilayered twinning/dislocation slip deformation microstructures provide a novel approach controlling balance uniform elongation yield strength β-type titanium alloys.
