Two-stage aging tr.atm.nt to acceler.te aging kinetics without im.air.ng str.ngth in B_4C/7A04Al com.osite

引用

Science China(Technological Sciences) 2024年第8期67卷 2485-2492页

作者： CHEN YunTao m. GuoNan ZHU ShiZe WANG Dong XIAO BoLv m. ZongYi Shi-Changxu Innovation Center.for.Advanced m.ter.als Institute of Metal ResearchChinese Academy of SciencesShenyang 110016China School of m.ter.als Science and Engineer.ng University of Science and Technology of ChinaShenyang 110016China Centr. of Excellence for.Advanced m.ter.als Dongguan 523808China

Aging tr.atm.nts ar. the key pr.cess to obtain satisfactor. str.ngth for.7xxxAl alloys and their.com.osites. However. tr.ditional single-stage(SS) aging is tim.-consum.ng to r.ach a peak str.ngth condition. In this study, an efficient 120℃ + 160℃ two-stage(TS) aging tr.atm.nt was pr.posed on a B_4C/7A04Al com.osite fabr.cated via powder.m.tallur.y(Pm. technology, which could acquir. sim.lar.peak-aging str.ngth but only took about 15% of the tim. com.ar.d to tr.ditional 120℃ SS aging. The evolution of pr.cipitation dur.ng the TS aging was investigated, as well as those of the 7A04Al alloys for.com.ar.son. In the second stage aging pr.cess, the higher.aging tem.er.tur. acceler.ted the nucleation of η′ phases inside the gr.ins and thus incr.ased the density of pr.cipitates. m.r.over. the shor. aging tim. lim.ted the coar.ening of pr.cipitates and the br.adening of pr.cipitatefr.e zones. The above factor. wer. beneficial for.quickly obtaining satisfactor. pr.cipitation str.ngthening effects. The B_4C/7A04Al com.osite exhibited slower.aging kinetics than the 7A04Al alloy in the TS aging. m. elem.nts consum.tion by the chem.cal r.action between B im.ur.ties intr.duced by B_4C par.icles and the Al m.tr.x was consider.d to potentially r.tar. the aging kinetics of the B_4C/7A04Al com.osite. Never.heless, the pr.cipitation sequence was not affected.
