摘要：

Four Ti-Cr-Nb alloys containing the C15 Laves phase have been given a series of mechanical tests, including compression, bending, notch toughness, elastic moduli measurement, microhardness, and a simple impact toughness test. Strength remains high between 900 °C and 1000 °C; moduli and specific moduli exceed those of titanium; 1000 °C ductility is substantial; but roomtemperature notch toughness is low. Since room-temperature impact toughness is substantial in unannealed samples, the effects of heat treatment will need to be studied. Oxidation rates have been measured on two of the alloys. © 1990 The Metallurgical of Society of AIME.
