4.1 Mechanical resistance. Ductility
Since tungsten is most often used at high temperatures, knowledge of its stress rupture, creep and fatigue behavior is essential. At low temperatures, ductility is particularly important. But tungsten's mechanical properties are highly dependent on its purity and manufacturing history. Wrought metal is stronger than recrystallized metal, and its mechanical strength is greater the lower the temperature at which it was wrought. In the same state of recrystallization, sintered...
