Introduction Since the invention of stainless steel at the beginning of the 20th century, it is recognized as one of the most important contemporary materials, especially in the construction fields [1].
It can not be corroded, rusted or frayed, and it’s also one of the highest strength construction materials.
The strength and hardness of metal materials is enhanced with the increase of the materials cold deformation extent, but the toughness and plasticity decreases.

The transition point depends not only on the properties of materials but also on the particle size of raw powders.
It indicated that the apparent brittle to ductile transition occurred in the materials.
