Abstract. A systematic study on the structural and magnetic properties of alloys (, in wt. percent) obtained by mechanical alloying is presented. Elemental powders of Fe and Co mixed in an adequate weight ratio were milled at room temperature in a shaker mixer mill using vials and balls of hardened steel as milling media with a ball : powder weight ratio of 12 : 1.

The ball-milling of pure Fe and Zn elemental powders corresponding to the Г-(Fe 3 Zn 10), Г 1-(Fe 5 Zn 21), δ-(FeZn 7), and ζ-(FeZn 13) compositions yields metastable crystalline phases. This is demonstrated by the peaks observed in the DSC measurements of the different phases.

01-03-2012· This paper presents the prediction of micro-milling forces using cutting force coefficients evaluated from the finite element (FE) simulations. First an FE model of orthogonal micro-cutting with a round cutting edge is developed for Brass 260. The simulated cutting forces are compared against the experimental results obtained from turning tests.

The as-prepared [email protected] 2 showed superior piezo-catalytic activity via ball-milling activation. The characterization and density functional theory calculation results demonstrated that the high piezoelectric property of [email protected] 2 is ascribed to its few-layered microstructure and semi-metallic nature.

A random solid solution of Mn in the α-Fe matrix is found for milling times up to 15 h. Mn segregation is observed after 25 h. The evolution of the relative percentages suggests that ball milling brings about processes that on the one hand induce the fcc/hcp martensitic transformation, and on the other favour transformations towards the phases dictated by the thermodynamic phase diagram.
