Abstract:In the paper, authors present the basic principles and technological features of the new processing technologies of the metalmatrix composite, such as self propagating high temperature synthesis.XD synthesis, Directed metal oxidation (Dimox) synthesis, Lancide synthesis and Spray- Atomized and codeposied synthesis,illustrate the mechanical properties of the metal matrix composites produced by the above- mentioned approaches, analysis advantages and shortcomings of different approacbes and pointout that SHS,XD,Dimox and Lanxide approach belong to the in stiu processing. Composites containing reinforcement generated in stiu are likely to have the advantages of .virgin uncontaminated intedeces and can be fur,ther tailored during sikudufucation processing to promote adequate bonding between the matrix and the reinforcements. In addition,this route of synthesis of composites may be more ecnomic as the reinforcements are not tnanufactured and handled separately.The shortcomings of the .in stiu processing are that the composites POssess low density and the quantity of the reinforcements can not be controlled easily. Spray atomization and codeposition processes belong to the rapid solidification technology.The basic thenes of the new processing technologies above should be created as the processiny,technologics are imprproved further.

Abstract:In order to give a necessary information for the research on Bi system superconductor, the newest results of phase relations in Bi-Pb-Sr-Ca-Cu-O system since 1991 have been reviewed, which include Ca-Cu-O ternary, Sr-Cu-O ternary, Bi2O3-CuO pseduo-binary, (Bi, Pb)2Sr2CuOx-CaCuO2 pseduobinary, Bi2O3-CaO-CuO pseduo-ternary. Bi2O3-SrO-CaO pseduo-ternary and Bi2O3-SrO-CuO-MO(M =Ca, Pb) pseduo-quarternary system. In addition. the new result of Ag-Cu-Pb-O system has also been discussed which is related with Bi(2223) / Ag tape and Ag-doped Bi-based Superconductor.

Abstract:The possible slipping and twinning modes in hop metals are summarized. The slipping plane includes (0000) hasal. (1100)prismatic plane and c-type. c+a-type Pyramidal plane. {1012}. {1121}and {112 2}are the primary twinning modes. {1011} {1124}and {1123}type twins are possible to appear in Ti and Zr.The relationship between slipping mode and the tasting temperature in Ti and Zr is discussed. The slipping planes arranged in order of ease of operation are prismatic.pyramidal and hasal planes.

Abstract:This paper describes the main character and important application of beryllium materials in the world high technology, as well as the production and application of beryllium in China.

Abstract:Miedema theory has been applied to studying systematically the thermodynamical properties of rare earth-magnesium. The eding enthalpies of liquid alloys and formation enthalpies of intermetallic compounds have been calculated. The calculations agree well wity the available experimental resultS or the predictions of other authors.

Abstract:Pole figure and inverse pole figure are introduced firstly, and both of them have been widely used in texture analysis as they are convenient in determining and recognizing. Then, the following are presented in details: the orientation distribution function (ODF), principle and calculation -process. The influence of Friedel Law on the results of ODF analysis, as well as much attempt to get complete ODF are also introduced in the present paper. Maximun Entropy Method applied to ODF analysis is considered to be better way for quantitative texture analysis. Texture quantitative result will be more real if Maximum Entropy Method is introduced to ODF analysis.

Abstract:利用正交設(shè)計(jì)實(shí)驗(yàn)的方法安排了一組Ｚｒ－Ｎｂ二元合金，考查了兩個(gè)水平的Ｎｂ含量，淬火溫度，時(shí)效溫度，時(shí)間以及合金組織狀態(tài)對(duì)耐蝕性能的影響，５００℃蒸汽腐蝕結(jié)果表明，Ｎｂ含量控制在固溶極限范圍內(nèi)Ｚｒ－Ｎｂ二元含金具有較佳的耐蝕性，而當(dāng)Ｎｂ含量較高時(shí)，采用雙相區(qū)淬火，較高溫度長(zhǎng)時(shí)間時(shí)效處理是獲得較好耐蝕性的工藝方向。

Abstract:Apresentation is given of the discribtion of wave pattern,vartex, meten zone in the interface of explosive bonded layer metal composite by means of melallographic observation. The issues, which should be pay attention to also introduced for explosive bonded layer metal composite.

Abstract:研究了加工熱處理工藝對(duì)Ｚｒ－４合金管材機(jī)械性能和耐蝕性能的影響。實(shí)驗(yàn)表明，工序中加入β淬火處理，可以改善合金的性能。擠壓前坯料β淬火后直接軋至成品的管材，再結(jié)晶退火后在３７５℃下的屈服強(qiáng)度為２０４￣２１８ＭＰａ，較經(jīng)過(guò)多次軋制到成品的管材，其屈服強(qiáng)度提高了４２％￣４７％。加工過(guò)程中降低中間退火溫度，減少加工道次的管材，在相同條件下的屈服強(qiáng)度為１８０￣１８８ＭＰａ。對(duì)合金管材進(jìn)行了４００℃和５００℃
