In the recent ten years, science and technology engineers made extensive research and mechanism discussion on high-density tungsten alloys used in armor-piercing shell.
They have got fruitful progress especially on the aspect of adding alloy elements and deformation strengthening,
which made great promoting effect on strengthen the armour piercing power of China''''''''''''''''s armor-piercing shell and catching up with the world advanced level.
However, due to various reasons, there are various problems.
First of all, as the tungsten carbide technology opened to the public, some colleges, universities and scientific research
institute carry on research in this area.
It greatly promoted the material properties of tungsten alloy, but as the research scope expands, low level and repeated
research phenomenon also becomes more and more serious.
