【摘要】 本文研究了经长时间（100个时）高温热处理之后碳-铝复合材料的拉伸强度和碳化铝（Al₄C₃）量变化的情况。观察到碳—铝复合材料在495℃长时间热处理其强度降低,在540℃长时间热处理其强度明显下降。碳化铝的数量和强度值在某一温度对在某一时间之后变化趋于平缓。更多还原

【Abstract】 The change of the tensile strength of the C/A1 composite wiras and the content of the aluminum carbide in the interfaces have been studied. The authors note the strength of composite wires was damaged after long period beat-treatment at 495℃ and was damaged remarkably above 540℃, and the content of the aluminum carbide increases with increaasing the temperature and the lime of treatment.更多还原
