| Abstract: | This paper deals with the banalysis on microstructure and fracture morphology of beryllium copper alloys (QBc2) after step ageing in hard condition by SEM and TEM. The optimum heat treating cycle is suggested. he observation result denodes that, after step age- ing, the alloying precipitated particles are obviously dispersed, the strength and the toughness of this alloys may be further increased. |
