The result shows improving complex sample's temperature is good to gain metallurgical bonding interface.
实验结果表明：提高浇注时复合试样的整体温度有利于获得界面的冶金结合。
The interface layer of metallurgical bonding will not induce brittle fracture and will share the ductile SEM fractographs of the substrate.
这种界面冶金结合层并不会引起脆性断裂，具有与基材相同的韧性断口形貌。
