Machine learning(ML) assisted high-entropy alloys(HEA) design is dedicated to solving the problem of long period and high cost of designing by traditional trial and error experimental methods. The classic AlCoCrCuFeNi HEA was taken as the research object. The phase structure prediction model and hardness prediction model were established respectively. https://tvtdogiq3erw8r.tokka-blog.com/35182776/effects-of-urban-parks-on-housing-prices-in-the-post-covid-19-pandemic-era-in-china
