This technique has been incorporated into a Defence Science and Technology Organisation proprietary crack growth analysis tool based on plasticity-induced crack closure.
Taking into account the elastic-plastic response of the material results in a reduction of the stress near the hole thereby reducing the stress intensity factors calculated.

In general, the role of materials for X rays can be represented as , where the refractive index decrement determines the phase shift of the X rays passing through the object.
Therefore, X-ray phase contrast imaging is more sensitive than traditional X-ray absorption technique in the fields of medicine and material science, etc.
It includes three gratings, a conventional X-ray tube, precision machinery stepping device, detector, biological samples or soft materials tested and the computer image processing unit.

Many surface treatments have been researched by materials scientist workers on the protection for magnesium and its alloys.
More many scientists have focused on amorphous materials in recent years because of their excellent performances.
And amorphous materials can also be prepared by using thermal spraying technique with its rapid cooling advantage[6-7].
Among these thermal spraying techniques, HVAS processing don’t need amorphous powder materials as spraying materials by comparison with other thermal spraying techniques[6-7].
