연구분사침적초고강려합금적자연시효시간0.25,0.5,1,2,2.5,3 a적역학여조직행위.결과표명:재전2 a내,합금적항랍강도화굴복강도수자연시효시간적연장이증강,최대항랍강도체도810 MPa,이신장솔칙종최초적11%감소도6%;자연시효2.5 a,합금적항랍강도감소도750 MPa,이신장솔제고도10%;시효3 a후,합금적항랍강도증강도800 MPa,신장솔강저도8%.
The natural aging behavior of spray formed superhigh aluminum alloys was researched,and the aging time was choosed as 0.25,0.5,1,2,2.5,3 a. The results show that at the first 2 a,the tensile strength is increased as the aging time,the tensile strength is up to 810 MPa for aging time of 2 a. And the elongation is reduced as the aging time,the elongation is reduced from 11%to 6%. After 2.5 a aging,the tensile strength reduces to 750 MPa,and the elongation increases to 10%;after 3 a aging,the tensile strength increases to 800 MPa,and the elongation reduces to 8%.
