Preparation of Aluminum Matrix Composite by Pressureless Infiltration Process李崇俊,马伯信,王抗利摘 要:ＰｒｅｐａｒａｔｉｏｎｏｆＡｌｕｍｉｎｕｍＭａｔｒｉｘＣｏｍｐｏｓｉｔｅｂｙＰｒｅｓｕｒｅｌｅｓＩｎｆｉｌｔｒａｔｉｏｎＰｒｏｃｅｓＬｉＣｈｏｎｇｊｕｎ,ＭａＢｏｘｉｎａｎｄＷａｎｇＫａｎｇｌｉ(李崇俊)(马伯信)(王抗利)Ｔｈｅ４３ｒｄＲｅｓｅａｒ...关键词:......
by pressureless reactive infiltration of CuTi alloy into carbon fiber preforms. The microstructure of composites and interface reaction was investigated by X-ray diffractometry, energy dispersive..., and then pressureless infiltration becomes available. The titanium carbide precipitates in the liquid metal around the carbon fiber in the form of solution-separation style. The titanium carbide......

Processing and mechanical properties of network ceramic/steel composites by pressureless infiltrationYANG Shao-feng(杨少锋)1, CHEN Wei-ping(陈维平)2, WANG Zai-you(王再友)1, CAI Yun-jie(蔡云杰)1(1. School... were investigated by SEM, EDS and compressive test. The results show that the depth of infiltration is about 40 μm to the bonding interface of ceramic/steel and the fracture strength σmax and plastic......
a fracture toughness of 8.6 MPa×m1/2. Reactive melt infiltration is pressureless reactive melt infiltration for short. It is a process in which the only driving force for spontaneous infiltration... and pressureless reactive melt infiltration. Thermodynamic calculation, phase analysis and microstructure analysis show that Al melt reacts with TiC and Ti2O3 simultaneously, leading to the formation......
Preparation of High-Strength Al–Mg–Si/Al2O3 Composites with Lamellar Structures Using Freeze Casting and Pressureless Infiltration TechniquesPing Shen,Juwei Xi,Yujie Fu,Alateng Shaga,Chang Sun... with a molten Al–12Si–10 Mg alloy(in wt%)by pressureless infiltration at 1,223 K in a N2 atmosphere, yielding the shell-like structure of the composites. The compressive strength of the upper part composite......
spontaneous infiltration, a TiO2 to Al blending ratio around 3:7 in volume and an infiltration temperature around 900 °C are the most suitable. Key words: spontaneous infiltration; pressureless sintering... preparation, preform forming, sealing into Al alloy molds and pressureless infiltration. Anatase TiO2 powders (<45 μm, from Sigma Aldrich) and Al powders (<45 μm, from Alfa Aesar) were used as starting......
