| titleOfInvention | High-plasticity and high-strength cast beryllium-aluminum alloy and preparation method thereof |
| abstract | The invention discloses a high-plasticity and high-strength cast beryllium-aluminum alloy and a preparation method thereof, and the beryllium-aluminum alloy comprises the following components in percentage by weight: 56-65% of beryllium (Be), 33-42% of aluminum (Al), 0.7-1.0% of nickel (Ni), 0.3-0.6% of lithium (Li), 0.5-1.0% of germanium (Ge) and the balance of inevitable impurities. The casting beryllium-aluminum alloy with high sphericization degree of beryllium crystal grains and high strength and plasticity is obtained by adding metals other than rare earth elements to modify the microstructure of the alloy and combining the working procedures of high-temperature smelting, two-stage heat preservation, homogenization and hot rolling. The alloy of the invention has relatively low cost, uniform and compact alloy structure, less casting defects, short production process flow, relatively low technical difficulty, alloy strength and plasticity close to or higher than those of powder metallurgy beryllium-aluminum alloy, and good application value. |
