New materials, also known as advanced materials, refers to recent research success and being developed has excellent features and functionality to meet the needs of high-tech new materials. The new material is the material basis of military weapons and equipment, the new generation is a key technology in today's world the military field. The military is a new material technology and new materials technology for the military field, is the key to modern sophisticated weaponry. The melting point of tungsten metal in the highest, and its prominent advantage is to bring high-melting material good high temperature strength and corrosion resistance, especially in military weapons manufacturing industry showed excellent properties. In the weapons industry which is mainly used in the production of armor-piercing warhead, the main battle tank has a large aspect ratio penetrators, small and medium-caliber anti-aircraft armor-piercing kinetic energy penetrators and ultra-high speed core material with a bomb.
Tungsten alloy powder pretreatment technology by and large deformation strengthening technology, grain refinement of materials, elongated grain orientation in order to improve the toughness and penetrating power of the material. Our main battle tank developed 125Ⅱ type tungsten penetrator core material for the W-Ni-Fe, using variable density compacts sintering process, the tensile strength of 1200 MPa average performance reached more than 15% elongation, tactical and technical indicators for 2000 m from the breakdown of 600 mm thick homogeneous steel armor.
