[more ▼] The creep behaviour of the ternary Zn—A1—Cu alloy after thermal treatment at ioo oc has been studied. The applied creep stress does flot modify clearly the transition phases (OL, T% ‘11m) appearing during isothermal ageing. During the creep test, the formation of an important density of defects resuits in the precipitation of T’ and O’ particles. The quantity of these phases depends on the creep conditions.

[more ▼] The phase formation during ageing of ZrH2 wt% AI and Zna27 wt.% AI alloys at 100 O has been studied by means of transmission electron microscopy and electron diffraction. No formation of ellipsoidal precipitates of GP 2 and c4 phase bas been observed. Precipitation of hexagonal phases occurs generally on account of the a phase. The <011> habitus plane of a new phase q has been found. The q phase has been distinguished from the metastable Qm using Moire patterns [less ▲] Detailed reference viewed: 16 (2 ULg) |
