Abstract
The invention discloses a movable shear blade. The movable shear blade comprises a metal body made of an alloy material treated thermally. The alloy material is prepared from 1-2% of As, 0.5% of Se, 0.7% of N, 0.9% of Au, 0.9% of Tc, 0.7% of Ba and the balance Fe and unavoidable impurities. The alloy material is thermally heated through the following steps that firstly, the temperature is raised to 665 DEG C at the speed of 25 DEG C/min and is kept for 2.5 h; secondly, the temperature is lowered to the room temperature at the speed of 30 DEG C/min; thirdly, the temperature is raised to 765 DEG C at the speed of 15 DEG C/min and is kept for 3 h; fourthly, the temperature is lowered to the room temperature at the speed of 25 DEG C/min. The metal body of the movable shear blade is good in performance and long in service life.
