摘要：

The slip systems and plastic properties of normal and transition hexagonal metals are briefly reviewed. In the case of titanium, there is strong evidence that the core of screw dislocations has a sessile three-dimensional configuration, so that the lattice friction on screw dislocations governs the low-temperature plasticity. The mechanical behaviour of Ti-Y alloys is explained by the removal of oxygen atoms from the titanium matrix below 400 K, by oxide dispersion strengthening and by dynamic strain ageing caused by the residual interstitial concentration at medium temperatures.
