Abstract
The effect of laser shock peening on α→ω phase transformation in high-purity titanium were investigated by means of X-ray Diffraction (XRD) and transmission electron microscopy (TEM) observations. The results showed that all the high-purity titanium samples underwent α→ω phase transformation under laser shock peening. The orientation relationship was {0001}ω//{11–20}α, which was consistent with the Silcock pathway. The α→ω phase transformation in high-purity titanium samples were related to the experimental parameters and the purity of samples. The fraction of transformed ω phase increased with pulse laser energy, pulse width and the number of impacts. Lots of nano twins were observed in the TEM micrographs. The coherent twin boundaries of nano twins may activated α→ω phase transformation in high-purity titanium under laser shock impacts.
