I declare that I don't know anything about metallurgy. I uploaded this manual only because I have this resource and I am willing to share it with others so that people with this need can do more with less. This manual has a total of 1781 pages, divided into 11 articles, covering a variety of new materials and related quality inspection standards for powder materials, which is a rare and good information for inspection and R&D personnel in the industry.
