| Abstract: | Motor engine exhaust manifold, which are usually made of HT250 cast iron and a little ductile iron domestically are used under severe conditions Due to the increased emission standard and operation temperature, the traditional materials can not come up to the standard of environmental protection and desired performance. The application of the new material and its improvement of operation performance and service life by alloying and controlled tissues are discussed in the paper. |
