Abstract

The martensites in Ti-Cu alloys containing up to 8 wt pct Cu have been examined using transmission electron microscopy techniques. The martensite has a massive morphology in the alloys which contain 4 pct Cu or less, whereas the alloys containing 6 and 8 pct Cu exhibit acicular martensite. Experimental evidence is presented to show that the lattice invariant deformation in the massive martensite occurs by internal slip with a Burgers vector\(1/3[2\bar 1\bar 13]\) and these results are discussed in terms of recent calculations. The transition from the massive to acicular martensite morphology is also discussed.
