Ball milling induced crystallization of amorphous Fe90Zr10 ...

Ball milling of melt-spun Fe 90 Zr 10 ribbons in a planetary ball mill (AGO-2) induces their crystallization into supersaturated α-Fe(Zr) grains. The crystallization degree of the amorphous phase increases with increasing milling time, with a fully crystalline state being obtained after 30 min at a milling speed of 1000 rpm.

Influencing the crystallization of Fe80Nb10B10 metallic ...

Nov 25, 2017 · Ball milling progressively hinders the formation of Nb 5 Fe 33 B 10 as primary crystallization product and promotes the formation of α-Fe at low temperatures. This behavior is visible already in the powder milled for 20 h (Fig. 2 (b)), where α-Fe and Nb 5 Fe 33 B 10 coexist up to 998 K.

Ball milling induced abnormal crystallization behavior of ...

This stone investigates the effect of milling atmospheres on mechanical crystallization of an amorphous Fe 78 Si 9 B 13 alloy during ball milling. Under an air atmosphere, the amorphous alloy completely transforms into a single α-Fe(Si) phase after milling of 30 h.

Ball-milling-induced crystallization and ball-milling ...

It was found that during ball milling, crystallization occurs in the amorphous ribbon sample with precipitation of an α-Fe solid solution, and the amorphous sample crystallizes completely into a single α-Fe nanostructure (rather than α-Fe and borides as in the usual thermal crystallization products) when the milling time exceeds 135 hours. The volume fraction of material crystallized was found to be approximately proportional to the milling …

Apr 15, 2018 · Amorphous Cu 50 Ti 50 alloy was prepared by short-term (20 min) high-energy ball milling. Cu 50 Ti 50 consists of amorphous matrix (93%) with a nanocrystalline (2–8 nm) inclusions. Activation energy of crystallization (199 kJ/mol) was obtained by Kissinger method.

The glass transition and crystallization of ball milled ...

May 27, 2010 · Abstract. Samples of ball milled cellulose were prepared by ball milling pulps from eucalyptus and softwood (spruce/pine). Water sorption isotherms were obtained by both dynamic vapor sorption and equilibration over saturated salt solutions, in the water content range of 5–42% db (db = dry basis; water as a % age of total solids).

Nanocrystalline materials prepared through crystallization ...

The crystallization induced by mechanical milling and thermal annealing are compared and it is suggested that the induction of crystallization by ball milling may be a promising technique for preparing soft magnetic materials in powder form.

Nano Ball Milling - SlideShare

Dec 15, 2012 · Nano Ball Milling 1. BALL MILLING METHOD By Aravind N. B 2. Nano materials can be defined as those materials which have structured components with size less than 100nm at least in one dimension. Nanotechnology is an advanced technology, which deals with the synthesis of nano-particles, processing of the nano materials and their applications.

Role of local heating in crystallization of amorphous ...

It was found that during ball milling, crystallization occurs in the amorphous ribbon sample with precipitation of an {alpha}-Fe solid solution, and the amorphous sample crystallizes completely into a single {alpha}-Fe nanostructure (rather than {alpha}-Fe and borides as in the usual thermal crystallization products) when the milling time exceeds 135 hours.

Ball mill - Wikipedia

The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet ...

Amorphization of graphite induced by mechanical milling ...

Jan 31, 2011 · Amorphization of graphite as a result of prolonged high-energy ball milling was directly observed with HREM. The exothermic peak in the DTA trace of the ∼200 h ball-milled sample indicated a crystallization onset temperature of about 670 °C and crystallization activation energy of 234 kJ/mole.
