研究了利用液态反应法制备的Tic颗粒(Ticp)增强铸造Fle-cr-Ni基复合材料的显微结构和力学性能。该复合材料主要由r基体和均匀分布的尺寸为1-5um的球状或多面体状TiCp组成.r/Ticp界面洁净,两相靠近界面的区域内均存在高密度位错。(Ti+c)加入量(质量分数)为3%-6%时复合材料的常温和高温拉伸性能比基体合金明显提高,其拉伸断口在800℃时仍能保持韧性断裂特征。

【期刊论文】原位Tic颗粒增强Fe-cr-Ni基复合材料的高温蠕变行为*

在973-1123K和40-160MPa条件下研究了含5%,10%,16%(体积分数,下同)原位Tic颗粒增强的Fe-26Cr-14Ni基复合材料的高温蠕变性能。原位TiC颗粒明显改善了Fe-26Cr-14Ni基复合材料的高温蠕变性能。含5%和10%TiC复合材料的抗蠕变能力比基础合金增强。随着TiC颗粒体积分数的增高,复合材料的蠕变速率降低而蠕变激活能和临界应力提高。TEM显微组织观察表明,复合材料的蠕变主要是以局部位错攀移机制进行的。因此,所有蠕变速率可以由应力指数为5的指数方程经归一化处理得到。

【期刊论文】Rapid solidif ication of Al218 %Si hypereutectic alloy in drop tube
王执福, WANG Zhi-fu, GUO Feng YU Hua-shun, CAO Chong-de, WEI Bing-bo
Trans. Nonferrous Met. Soc. China, 2000, 10 (6): 769~771,-0001,():

The drop tube technique was performed to achieve rapid solidification of undercooled Al218 %Si hypereutectic alloy. The droplets ranging from 60~1 000μm in diameter were obtained. The regular polygonal primary Si and lamellar eutectic homogeneously distribute on α(Al) matrix in the droplets larger than 500μm. While in the droplets smaller than 500μm the five2star primary Si was found , which is often accompanied by some spherical eutectic grains. The different morphologies of primary Si are due to varied undercoolings. Scanning electron microscopy suggests that the spherical eutectic grain is composed of anomalous eutectic in its core and lamellar eutectic radiating outside from its periphery. Such eutectic microstructure is presumed to be the result of combining large undercooling , microgravity with containerless processing during free fall.

The interface structure of as-cast Fe-Cr-Ni/TiC(p) composite prepared by a liquid state in situ process is studied by using TEM. Its crack propagation feature in the process of in situ TEAt tension was also investigated. It is shown that the interface between TiC and "/-phase is clean and tidy. No reactant is produced. The orientational relationships of TIC/r interface are as follows: (200)r// (220)TIC, [O01]r// [OO1]TiC, (200)r// (2OO)TiC, [O11]r// [011]TiC. Crack firstly propagates into the matrix along grain boundary (GB) because the particulate reduces the intensity factor of stress around crack tip. Interface becomes the channel of crack propagation when crack tip is closed by the action of lattice defects. The propagation along interface causes the distortion of lattice and the piling-up of dislocation in matrix that is near the interface. Lastly, the crack changes the direction to propagate into TiC phase along subcrystalline boundary or as cleavage. The mechanism of cleavage propagation is considered that Lomer--Cottrell dislocation reaction takes place at the connection of (010) and (101) to produce high stress concentration. This reults, in the initiation of microcrack and propagation of cleavage crack between (111) planes.

The initiation and propagation of the short fatigue crack in a l0vol.% titanium carbide particulate reinforced cast Fe-26Cr-14Ni matrix composite at 1023K were investigated. It is shown that the titanium carbide particulate may hinder the crack propagation and fatigue fracture of the composite. The relationships between fatigue crack propagation rate and stress intensity factor are da//dN=4.2

In order to design a new kind of low-cost high-temperature ferrite-austenite duplex alloy, the effects of carbon and chromium on the alloy solidification structure and properties have been investigated with orthogonal experiments. The addition of carbon promotes strongly the formation of austenite and that of carbides in the alloy solidification structure and refines the alloy grains. With the increase of carbon content, the alloy high temperature strength and oxidation resistance at 1250C Improves at first, but then begins to deteriorate greatly when the carbon content exceeds 0.15%. The addition of chromium facilitates the formation of ferrite in the alloy solidification structure. As the chromnium content increases, the alloy rupture strength at 1250C initially is enhanced, but then reduces rapidly, while the alloy oxidation resistance improves continuously.

In order to design, a low-cost high temperature lerrite alloy, the effects of carbon, and titanium on its, solidification structure and properties have been studied. When the carbon content is increased from 0.07 to 0.35wt%, the alloy grains becomes finer, and the grain boundaries become wrder and more zigzag. The alloy oxidation weight-gain rate at 1300C keeps increasing clearly however, that at 1350C decreases at first then increases. When the carbon content is above 0.15, wt% the alloy strength at 1300C decreases acutely When the titanium content thoreased trom 0.30 to 0.60wt% the alloy, grains became fine andboth the alloy strength and oxidation resistance improved remarkably 2001 Elsevier Science Ltd.
