The Results indicated that when the steel with the better uniformity of the microstructure,the smaller average effective grain size,the milder banded structure,the smaller and the better uniformity of M-A,its DWTT property is better.

Nondestructive evaluation of average grain size of coarse grain materials based on ultrasonic transmissive technique;

The influence of current density on the microstructure such as average grain size and texture of Ni coatings was studied as well.

The average grain size and microstructure of the nickel nanocoatings heated at different temperature for 2 h and Ni/carbon nanotube composite nanocoatings were examined by X-ray diffractometer(XRD),and their wear behaviour and microhardness were investigated.

It has been showed that the equivalent grain size increases with increasing deformation temperature and decreases with increasing deformation degree and strain rate Recrystallized grain volume decreases with increasing deformation temperature and increases with increasing strain and strain rate .

The oxidation mechanism was well explained by reactive element effect and grain size effect.

Influence of wire rolling process parameters on austenite grain size of high carbon steel;
