| 摘要 |
2047197 9011382 PCTABS00002 The toughness of Al-Li, Al-Mg and Mg-Li alloys is increased by a melting and refining process designed to reduce the concentration of alkali metal impurities below about 1 ppm and preferably below about 0.1 ppm (Fig. 1). The hydrogen and chlorine gas constituents are also significantly reduced.
