✦ Synopsis

Intercrystalline cavities formed during high-temperature fatigue have been examined. Their nucleation is thought to be heterogeneous at oxide or other particles; their growth is attributed to vacancy condensation. OBSERVATIONS FRACTOGRAPHIQUES DE LA FORMATION DE CAVITES PAR FATIGUE A TEMPERATURE ELEVEE On a examine des cavites intercristallines form&es pendant un effet de fatigue a temperature elev&. On croit que leur nuclearisation est heterogene dans lea cas d'oxydes ou d'autres particules; on attribue leur croissance a la condensation dans le vide. FRAKTROGRAPHISCHE BEOBACHTUNG DER HOHLRAUMBILDUNG BE1 HOCHTEMPERATURERMUDUNG Bei der Hochtemperaturermiidung entstandene interkristalline Hohlriiume wurden untersucht. Man kann annehmen, dass sie heterogen an Oxyden oder anderen Teilchen entstehen. Ihr Wachstum wird auf Leerstellenausscheidung zuriickgefiihrt.

Intergranular cavitation has been observed in nickel during low-cycle fatigue at temperatures and strain-rates where there was little or no grain boundary sliding. The cavities were found to nucleate early in fatigue life and were associated with impinging crystal-slip traces at the boundaries. Impl

The high temperature oxidation of ethyl tert-butyl ether (ETBE) with oxygen in argon diluent has been studied in reflected shock waves over the temperature range 1160 to 1830 K, with pressures of 3.5 bar and with varying equivalence ratios from 0.3 to 2.4. Measurements of the ignition delay times, c
