| Abstract: | DWTT property with different microstructure were investigated, and analyzed the influence to DWTT from the aspect of percentage composition and size of inclusion, also the SEM pictures of typical silicate inclusions and sulfide, oxide inclusions were provided. From the pattern of M/A island corroded by lapare reagent, the influence of M/A to DWTT was analyzed，and also the strengthen mechanics of dislocation and precipitation was analyzed。 |
