Effect of an electromagnetic field on precipitates in the composite interface of Al-Mg/Al-Si;
电磁场对Al-Mg/Al-Si复合界面析出相的影响
Densities of the composites with or without C/SiC interphase are about 1.
当C/SiC界面涂层存在时,气相渗硅C_f/SiC强度为239。
The interphase of glass state carbon appeared between the matrix and reinforced phase, which resulted in weak joint.
研究表明:材料表现出脆性断裂的破坏失效特征;SiCp/SiC复合材料内部颗粒间、团聚体之间残留的微孔和孔隙等薄弱环节使材料的强度降低;复合材料基体和增强相之间有一层由树脂热解而产生的玻璃碳,造成界面的弱结合,使材料强度不高。
