High-energy ball milling process of the adhesion properties of metal powder

Milled powder adhesion should play a decisive role in the body or not. The second step is the adhesion layer thickening. Real powder particles are in front of their adhesion and cold welding, which is a spontaneous thermodynamic process, the adhesion strength depends on the powder particles form the atoms bond strength and the ability to hit the ball the size of the third step is, revolves around (if the cold welding) and revolves broken tarsal layer peeling off the dynamic balance, then,[link widoczny dla zalogowanych], revolves with no increase in the thickness of boron, showing a dynamic equilibrium state. 4 Conclusion (1) by mixing high energy ball mill, Al strongly adhere to the walls of the tank ball and ball milling, the milled powder contamination A small】: Cu and w powder with almost no fools phenomenon. Fc milled powders led to the pollution load increases rapidly with the ball when asked. t2) under water cooling loop, with the process control agent added to increase the amount. AI in the iron content increased, while the iron content of Cu peak. (3) With the ball speed increases, Al powder in the iron content was less than the increase rate of follow precedent sets the amount of Cu powder in the increase rate of iron Reference:: l: Yv. nPJ, SchwarzRBElJIMa 【ur_Res, l993.81239: 2 a MamR, \i5 (i3) child 80: j: Colellc ('f port: MatersciForum.1995, 179/i8325: = l b 1wuNq, _jjaTaJ \7.88,90:367 [5] (; ~ manPs ...

After a peak appears. Gradually decreased, with the main softening mechanism is dynamic recovery and dynamic recrystallization. Zombies in the range of 450 ~ 500C concerned, the main softening mechanism is dynamic recrystallization.
