The evolution of microstructure and recrystallization texture of CSP cold-rolled sheet during annealing were investigated by EBSD. The results show that recrystallization of the tested steel is oriented nucleation. the cold-rolling texture are mainly the {111}<110>, {111}<112> and {001}<110>. The new recrstal grains are mainly the {111}<112> and {111}<110>, this two textures are generated each other. The texture {111}<112> and {111}<110> easily occurs in recrystalline temperature, the texture {112}<110> is generated during grain growth which have no effect on deep drawing property. So it is favorable to increase deep drawing property that the {111} texture formed in recrystallization temperature is stability existed and does not changed.

Simple structure, orderliness and few gray level of SMD (surface mounted device) resistor image are the prominent feature of SMD resistor units array, through binary resistor image, edge detection, line detection, with the correlation coefficient as a criterion for defects. A method for resistor flaw detection was proposed based on subgraph projection matching. The feature of resistor flaw was extracted on basis of the method of PCA (principal component analysis). Then the resistor flaw would be classified by SVM (support vector machine). At last, an experimental platform was built and the result verifies that the detection rate employed the proposed method is 92.5%, and the method meets the requirements on high accuracy and speed.

Alloy element and RE were added into the partial model of LFC casting to meet the special properties of partial component during LFC process. Alloy elements and RE can be dissolved into the corresponding position of the LFC castings. The results show that partial alloying treatment can effectively improve the partial special property requirements of LFC components.

Tooth surface peeling of the coach driving screw bevel gear was analyzed by means of macroscopic fracture observation, hardness test, microstructure examination. The result shows that the main reason of early peeling is the exceeding contact stress at the top of tooth caused by abnormal contact at the tooth surface. The weakened grain boundary and the thinner carburized layer aggravate the early peeling.
