Abstract

Twinning in a Ti−26Nb alloy during thermal cycling was investigated by transmission electron microscopy. The interrelationships between displacive transformation and twinning were proposed. Fine {112}_β1¯1¯1_β twins and preferentially formed ω particles were observed in the β matrix after 100 cycles. The {112}_β1¯1¯1_β twins nucleated in ω particles and grew by merging twin embryos. Upon further increasing the cycle number to 500, {332}_β113¯_β twins bounded with laminated α" martensite were observed instead. The interfacial twin boundary α" phase mediated the martensitic transformation of the adjacent region, leading to the formation of {332}_β113¯_β twins.
