精密模锻是一种特殊的热成型操作，特别适合利用铝材料的技术优势。精密模锻考虑了高材料利用率和更经济的生产，使零件具有与最终产品相同的功能表面。镁锂超轻合金代表了一组有趣的工程材料。本报告介绍了镁-锂系统以及使用MgLi粉末进行的初步实验室锻造试验的结果。

THE USE OF PRECISION DIE FORGING, A SPECIAL HOT FORMING OPERATION, IS PARTICULARLY SUITABLE TO EXPLOIT THE TECHNOLOGICAL ADVANTAGES OF ALUMINUM MATERIALS. PRECISION DIE FORGING CONSIDERS HIGH MATERIAL UTILIZATION AND MORE ECONOMICAL PRODUCTION FOR PARTS HAVING IDENTICAL FUNCTIONAL SURFACES AS END PRODUCTS. MAGNESIUM-LITHIUM SUPERLIGHT ALLOYS REPRESENT AN INTERESTING GROUP OF ENGINEERING MATERIALS. THIS REPORT PRESENTS THE MAGNESIUM- LITHIUM SYSTEM AS WELL AS THE RESULTS OF INITIAL LABORATORY FORGING TESTS CARRIED OUT WITH MgLi POWDER.
