Compared with traditional materials such as steel and aluminum alloys, materials have excellent performance in terms of strength, weight, corrosion resistance, and wear resistance. Therefore, their application in the military field is becoming increasingly widespread, and they are gradually showing a trend of replacing traditional manufacturing materials.
