Abstract:

Fracture behaviour of Gd2 (MoO4)3 single crystal, which is improper ferroelectric-ferroelastic, has been examined by means of point loading. There are three fracture planes in gadolinium molybdat (GMO): {100} - main cleavage plane, {210} and {110} - secondary cleavage ones. It is shown that cracks have a tendency to transit from secondary planes up to cubic plane and vice versa. This would be considered as the main cause of river pattern appearance on fracture surfaces of samples. Mechanical twinning and crack growth are independent channels for relaxation of elastic energy in GMO, which do not connected between themselves, so excluding of twinning leads to increase of crack length. © 1999 Kluwer Academic Publishers.
