The ball-milling process was applied to increase the sample density. Mn content was set to 25 or 35 wt.%, while 1 wt.% carbon was added to all samples. The austenite stability was independent of porosity and the ball-milling process, whereas hardness had a strong dependence on porosity and the ball-milling process.
With extension of ball-milling time, the temperature for maximum degradation rate reduced to 369.3 °C, 367.2 °C and 362.4 °C for BMC-15, 45 and 120 (Fig. S3a). However, the weight loss at each maximum DTG temperature showed a gradual increase (Fig. S3b), confirming the loss of stability after ball-milling treatments.
Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art - it's just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results.
