【摘要】：以機電一體化設(shè)備材料304奧氏體不銹鋼為研究對象,對其在不同熱處理下的微觀組織和力學(xué)性能進行研究。結(jié)果表明:不銹鋼為單相奧氏體組織,基材晶粒粗大且其大小長短極其不均勻;經(jīng)過冷軋?zhí)幚?其微觀組織晶粒大小很不均勻,分布紊亂;700℃保溫5h退火處理,晶粒大小略微均勻;800℃時效2h,晶粒大小比較細小、均勻;隨著溫度升高,鐵素體相質(zhì)量分數(shù)下降,奧氏體相質(zhì)量分數(shù)逐漸升高;隨退火溫度升高和時效時間延長,不銹鋼顯微硬度和抗拉強度逐漸降低,適量縮短固溶時間可以提高不銹鋼的力學(xué)性能。
[Abstract]:The microstructure and mechanical properties of 304 austenitic stainless steel under different heat treatment were studied. The results show that the microstructure of stainless steel is single phase austenitic structure, the grain size of the substrate is coarse and its size is extremely uneven, and after cold rolling, the grain size of the stainless steel is very uneven and its distribution is disordered. After annealing at 700 鈩，
