The results show that the composite compound observed is mainly composed of TiC, CaS and CeS; the nucleation sequence of the phases during the solidification of the alloy is CeS→TiC→austenite; the (100) crystal plane of CeS and the (001) plane of TiC, and (100) plane of TiC and (001) plane of austenite match perfectly; CeS can act as the heterogeneous nucleating center of TiC, and TiC can act as the nucleating center of austenite.

结果表明：试样中的复合化合物主要由CaS，CeS和TiC组成；合金凝固时的形核顺序为CeS→TiC→奥氏体；CeS及CaS的(100)晶面与TiC的(001)晶面、TiC的(100)晶面与奥氏体的(001)晶面匹配良好；CeS凝固时可作为TiC的异质形核核心，而TiC又可作为奥氏体的形核核心。

After quenching, the phases of the composite are as same as the as-cast composite, but the morphography of TiC particulate was transformed from square to sphere, some TiC particulates coarsen due to the precipitation of the solid-soluble TiC particulates; the other TiC particulates change into the smaller spherical particulates due to the solution of the sharpangled portion of the quadrate TiC particulates.

热处理后，复合材料的相组成不变，但是TiC颗粒由方形变成球形，固溶析出的TiC颗粒在某些TiC颗粒的表面沉积，使后者粗化；另一些方形颗粒的尖角处溶解形成直径更小的球形TiC颗粒。

For the composites with a low content of TiC particle, the rupture manner was mainly the nucleation of cavity and following ductility splitting fracture. But for the composites with a high content of TiC particle, the cracking and decohesion of TiC particles were the main rupture mechanism. For the composite containing a middle TiC content, the rupture mechanism consisted of the above two styles, but the former was the dominating mechanism and the later was the subordinate mechanism.

对TiC体积分数较低的钢基复合材料，拉伸过程中TiC颗粒界面上的孔洞形核及随后塑性撕开机制是其断裂失效的主要机制；对TiC体积分数较高的钢基复合材料，拉伸过程中TiC颗粒的开裂及脱落是其断裂失效的主要机制：对TiC体积分数介于上述两者之间的钢基复合材料，拉伸过程中TiC颗粒界面上的孔洞形核及随后塑性撕开机制在其断裂失效过程中占主要地位，而TiC颗粒的开裂及脱落占次要地位。

The results under the oil lubricate friction conditions were similar with those under the dry friction conditions. The wear mechanism of 3Cr13 matrix alloy was micro-cutting and distorting wear. For the composites with a low fraction of TiC particle, distorting wear dominated and cutting was partly operating. For the composites with a high fraction of TiC particle, stress fatigue wear and wear of hard phase decohesion has occurred, but the main wear mechanism was still distorting wear. When the wear experiments were performed under the oil lubricate friction conditions, the main wear mechanism has became to abrasive wear and fatigue wear for the composites with the low TiC fraction, and fatigue wear would be to dominate for the composites with the high TiC fraction. There were similar wear mechanisms in H13 and 1Cr18Ni9 matrix composites.

在干摩擦条件下，3Cr13基体合金的磨损机理为显微切削和变形磨损；低体积分数的复合材料磨损机制以变形磨损为主，兼有少量的切削磨损机制；高体积分数的复合材料磨损机制以变形磨损为主，兼有应力疲劳磨损和脆性相剥落磨损；在油润滑摩擦条件下，3Cr13基体合金的磨损以磨粒磨损为主；低体积分数的复合材料磨损为磨粒磨损和疲劳磨损；高体积分数的复合材料磨损以疲劳磨损为主。H13、1Cr18Ni9基体及其复合材料的磨损机制类似于3Cr13基体及其相同体积分数的复合材料。

The analyzed results about the forming mechanism of TiC indicate that the dendritical TiC is the primary TiC which freely grows in a continuous growth way in supercooling liquid metal before the peritectic reaction, and the short bar-like TiC nucleates and grows in β—Ti after peritectic reaction.

在对TiC形成机制的分析中认为，树枝状TiC是包晶反应之前过冷熔体中，以连续生长方式自由生长而成的初生TiC，而短棒状TiC则是包晶反应后在β-Ti的内部生核并长大而成。

Compared with that of 3Cr13 alloy, the oxidation resistance of the composites containing 5 vol.％TiC particle was improved greatly at 850℃, but the improvement was relatively limited at 950℃. But the oxidation resistance of 1Cr18Ni9 composites containing 5 vol.％ TiC particle was obviously improved at 950℃, and at 850℃ the improvement is not large. The TiC particle can improve the oxidation resistance mainly was by developing the oxidation selectiveness of the Cr element as to change the phase constitution of the oxidation film, to alleviate the production of the stress in the oxidation film and to improve the cohesive force of the oxidation film or matrix interface and the chemical combination of the oxidation film.

与3Cr13合金相比，含5％volTiC颗粒的复合材料在850℃的抗氧化性能得到大幅度提高，而在950℃复合材料的抗氧化性能提高作用却是有限的；与1Cr18Ni9合金相比，含5％volTiC颗粒的复合材料在850℃的抗氧化性能略有提高，而950℃复合材料的抗氧化性能提高却是明显的；TiC颗粒可以提高两种基体合金抗氧化性能，主要是通过促进Cr的选择性氧化，进而改变氧化膜的相组成、减缓氧化膜内应力的产生、增加氧化膜/基体界面凝聚力及提高氧化膜化学结合力而实现的。

Some methods aiming at the two problems have been researched. First, the optimal number of ATE site can be calculated based on a cost model of DAT-ATE. Second, the problem of test schedule which is equitant with two-dimensional Bin-Packing problem is presented. Then a TCG denotation satisfied with T-admissible rule is more convenient for combinational optimization. With Simulated annealing algorithm, better test scheduling results can be achieved; but there is no great optimization space because the efficiency of scheduling is greater than 90%. Third, A novel test compression method——Multi-capture testing is proposed to compress the stimuli. And the ATPG results show that MC achieves high compression ratio which is greater than 90% in some large-scale circuits. MISR, widely used in LBIST, is employed to compress the responses. The aliasing analysis demonstrates that the fault coverage reduction is little due to the existence of aliasing. Fourth, an improved TIC (called S-TIC) aiming at structured test is proposed based on ARM's TIC. A MC scheduling algorithm is proposed to compute the SoC test time and combine MC vectors to SoC test vectors. The scheduling results shows that test time is greatly reduced when using the proper scheduling priority.

首先，给出了低成本ATE的成本模型，根据此模型得到最低测试成本时系统级测试调度的基本参数——测试Site数；其次，本文将DAT-Scan方式的SoC测试调度等价为两维BP问题，为有效地求解该问题，将该BP问题表示为TCG图并通过模拟退火算法解决其求解过于复杂的问题，调度的结果表明该方法在测试时间上有一定改善，并指出DAT-Scan测试调度效率已经大于90％，进一步优化的空间较小；第三，本文尝试通过测试压缩来解决激励所需的测试带宽，提出了Multi-capture结构并解决了MC测试过程中的&矢量&退化问题，MC测试的ATPG结果表明其测试压缩率很高（大电路接近90％）；第四，在激励获得很高压缩比的情况下，测试响应也需压缩，本文采用LBIST中常用的MISR作为MC测试的响应压缩电路，理论分析和实验结果都证明了MC测试的别名对故障覆盖率影响较小（小于2％），并对两类别名的成因做了具体分析；第五，在MC测试及其响应压缩的基础上，本文改进了ARM公司的测试控制器TIC使之适合于MC测试，为了解决MC测试矢量合成问题，本文抽取了MC测试模型，通过固定优先级的MC测试调度模拟将MC矢量合成为ATE矢量，并模拟出了总的MC测试时间。
