Abstract:
A constitutive relationship has been applied to study the behavior of str uctures and composites of the shape-memory alloy(SMA).The predictability of the constitu tive relationship is confirmed by th e uniaxial and multiaxial examples.The paper gives out the finite element algorithmic implementations,which is appl ied to implement as umat of ABAQUS.As two kinds of applications,CT(compact tensile)and TPB(three point bending)specimens and SMA-fiber reinforced metal matrix and met-al-fiber reinforced SMA-matrix com posites are analyzed.The different distributions of martensite fracti on of the CT specimens and TPB-specimens made of SMAs are expla ined by the different stress characteristics ahead the cracks.The relative study on the SMA composites shows that the bulk mechanic behavior depends on the volume of SMA and the non-SMA matrix /fiber pro perties.

Abstract:
研究了Cr含量相对较高的Cu—Ni—30Cr合金在700℃-800℃，0．1MPa纯氧气中的氧化行为。结果表明：合金氧化动力学较复杂，其瞬时抛物线速率常数随时间而降低，氧化动力学曲线通常不是由单一的抛物线或直线组成而是由几段组成。Cu—Ni—Cr为三相合金，3相的存在增加了合金表面形成Cr2O3氧化膜所需临界浓度，但30at％Cr足以使合金表面形成连续的Cr2O3外氧化膜。氧化膜内层是合金和氧化物相共存的混合区，被氧化的岛状物是由Cr2O3和Cu，Ni组成。这种混合内氧化机制与经典内氧化明显不同。

Abstract:
The FGM is taken to be a ceramic -metal composite with its component changing with position in the FGM along with the thickness direction.The residual thermal mic rostresses analysis is important to determine the material system of FGM.Based on an elastic mechanics analysis according to a spherical sy mmetric model,the residual thermal microstresses are determined as a fu nction of the elastic properties of the ceramic and metal phases,and the location.The results show that the r esidual microstresses have a charac teristic of short -range dis-tribution.And the maximal stresses locate in the interface of ceramic an d metal phases at every graded layer.In the end,the residual thermal stresses of ceramic-metal interfac es in ZrO 2 /Ni FGM cooled to room temperature after sintering have been analyzed.The results show that many microcracks would likely develop in the matrix of FGM.

对以B4C为供硼剂、以Y2O3为催渗剂的WC—20Co硬质合金渗硼表面进行了从室温到1300℃连续升温渗硼过程的XRD动态物相分析，在此基础上探讨了钇—硼共渗机理。结果表明，在真空烧结升温期间，B4C分解出来的活性硼原子除了在压坯表面上形成硼化物外，还形成了硼原子富集。这些硼原子向压坯内扩散，形成弥散分布的羽毛状W2Co21B6化合物。同单独渗硼相比，钇在钇—硼共渗过程中有拓宽渗硼温度范围、促进B4C脱碳分解和硼原子向压坯内扩散等催化渗硼作用，从而改善了渗硼层的组织结构，明显提高了渗硼层的韧性。
