Abstract:研究了锡含量对锆－锡合金力学性能和腐蚀性能的影响。结果表明：锡在０．５ｗｔ％～１．７ｗｔ％范围内，随着锡含量的增加，合金的强度增加，在４００℃蒸汽腐蚀试验中，随着合金中锡含量的减少，腐蚀增重降低并能改善合金的抗疖状腐蚀能力。

Abstract:通过等温锻造方法对Ｔｉ－４７Ａｌ－５（Ｃ＋Ｖ＋Ｍｏ＋Ｎｂ）（ａｔ％）合金进行组织控制。研究发现，由于合金在凝固过程中存在两个包晶反应，导致枝晶间铝含量的分布极不平衡，从而使铸锭组织不均匀，含有大量的γ＋α２片层组织。在热加工中，片层组织在大变形量下发生剪切变形或严重弯曲。剪切变形组织沿平行于片层边界作用，使各片层团间产生大量再结晶晶粒并呈无序生长；而由于γ和α２取向关系发生畸变，γ和α２由片层形式趋向于等轴。本研究还对γ－ＴｉＡｌ合金再结晶机理进行了讨论。

They include high magnetic moment materials of Fe-N system, spin-valve giant magnetoresistive materials, new rare-earth permanent magnetic materials of Sm2Fe(17)Xy system, new design of magnetic levitation train, applications of high gradient magnetic separation technique and applications of microwave YIG ferrite.

Abstract:he systematical analyses on the rheological concepts and principles concerning the powder injection molding (PIM) process are carried out. The creeping regularities and the flowing rate distributions at the flow front in the cylinder cavity on the Newton flow, Power-law flow and Bingham flow, which are of great importance in PIM, are derived. Finaly, the rheological analysis in St3N4-binder injection molding system is discussed as an example of rheological principles and their application.

Abstract:he fracture behaviour of the sintered NdFeB permanent magnetic materials and the composition of phases on grain plane and grain boundary interface have been studied. It is shown that the fracture behaviour of the NdFeB magnets appear mainly intergranular facture and the grain boundary appears O-rich and Nd-rich. It is suggested that the intergranular Nd-rich film with oxygen located on the grain boundary is the main cause of the intergranular fracture of the magnets. The ways to strengthen the NdFeB Permanent magnetic materials have also been proposed.

Abstract:he diamond metalwork was made by the vacuum evaporateplated Ti on diamond and then POwder metallurgical sinterprocess. The results show that the vacuum evaporateplated. Ti on diamond has improved the infiltratity and surface activity of diamond, so that the rupture strength and surface abrasion resistance of the diamond metalwork are improved, and the working life of the diamond metalwork can be prolonged.

Abstract:A boronning method of porous stainless steel is introduced. Using this method, the porous body maintain its original porosity when its surface wearability is improved. The results indicate that deformation and peel of the sample can be avoided by boronning equal thickness at both surfaces of the sample. The boronned thickness are affected by boronizing temperature, time and the thickness of boronning agent.

Abstract:Ti / SnO2+Sb2O3+MnO2 / PbO2 anode has been studied by means of SEM and XRD. The lifetime and electro chemical kinematic parameter of electrod were determined. The anode is better than lead for treatment of coking waste water of containing phenol. The results show that the anode is a better electrocatalyst in sulfuric acid.
