摘要：

The characteristics of a new dispersion-strengthened bronze developed by the Mixalloy system were evaluated through their mechanical properties and compared to commercial phosphorous bronze. Annealing treatment in the temperature range 400-750 degrees C did not produce any difference in the tensile properties of dispersion-strengthened bronze, but increasing the cold-drawing ratios resulted in a rapid increase in the tensile and yield strength. The tensile and yield strengths of cold-drawn dispersion-strengthened bronze after extrusion decreased with increasing annealing temperatures, but did not decrease greatly in the temperature range above 500 degrees C. The new dispersion-strengthened bronze showed superior tensile and yield strengths at high temperatures compared with commercial phosphorous bronze.
