研究了中铝耐热球墨铸铁的组织与性能，结果表明，中铝耐热球铁比普通中铝耐热灰铸铁，常温强度提高 2倍以上，冲击韧度提高 3倍以上，抗氧化性能提高 10倍以上，热疲劳性能提高 3倍以上，是一种适用于 800～ 900℃条件下工作的新型耐热材料。
The results show that the heat-resistant ductile iron of medium aluminum is more than twice as high as ordinary aluminum heat-resistant gray cast iron, the impact toughness is increased more than 3 times, and the oxidation resistance is improved 10 times more than the thermal fatigue performance increased by more than 3 times, is a suitable for working under the conditions of 800 ~ 900 ℃ a new type of heat-resistant materials.
