摘　　要：研究了在500～900℃温度时效不同时间后，合金显微硬度变化规律、结果表明．经10％～20％冷变形后合金硬度显著提高，而且即使再经700℃高温长时间时效，形变强化效果也能保持；800℃时效时，当保温时间少于2h的情况下，合金才能保持冷变形强化效果；900℃时效时，冷变形强化完全消失。The microhardness variations of a cold-worked modified Inconel X-750 alloy aged at 500～900 ℃ have been tested and studied. It shows that the hardness of alloy obviously increased with cold deforming 10% ～20%, and the cold deforming strengthening effect was kept with the all0y aged at 800℃ for about less than 2 h, and with aged at 900℃, the deforming strengthening effect for the modified alloy couldn't be ob-tained.
