摘 要：Gas atomized 4J36 alloy powder was milled for 72 h then mixed with ZrW2O8 powder and sintered at 600℃ for 4 h under argon atmosphere.4J36/ZrW2O8 composites containing 10 vol.%,20 vol.%,30 vol.%,and 40 vol.% ZrW2O8 were fabricated,the relative density of which ranged from 70% to 80%.Thermal expansion coefficients of the composites decreased as the amount of ZrW2O8 increased,in agreement with the rule of the mixture.The coefficient of thermal expansion of the 4J36/40 vol.%ZrW2O8 composite in 25-100℃ is 0.55×10-6/℃.
