由国外先进材料的解剖分析看我国航空材料的冶金质量

Review of Metallurgical Quality for Domestic Aeronautical Materials from Examinating External Materials

通过解剖分析国外先进材料如高温合金、钛合金、不锈钢及焊丝和焊料， 了解和掌握了国外材料的冶金质量与水平， 找出了国产材料与国外先进材料的差距， 提出了提高国产材料冶金质量的途径。

The metallurgical quality of external materials was mastered by means of examinating external materials such as superalloys, titanium alloys, stainless steels, welding rod and solder The superior metallurgical quality of external materials rests with the strict contronl for impurity elements and scatter of alloy elements The method of improving metallurgical quality of domestic material was proposed
