Abstract A new method for the preparation of amorphous alloys is the mechanical alloying process. So far, three amorphization reaction types were observed when this technique is used. Which reaction type occurs depends on the local conditions during the milling, such as impact energy and local temperature just after an impact.

Starch crystallinity degree decreased by ball milling due to starch amorphization during this process. An excellent correlation was found between crystallinity degree obtained by WAXS and ATR FTIR data for the whole ball milled analyzed samples. The energy required for size reduction was satisfactorily explained using a generalized grinding.
This suggests that amorphization in metal metalloid systems, i.e. ductile brittle systems, like Fe40Ni40P14B6 is fully achieved by ball milling alone using high milling energy and metalloid.
Abstract. We report on the crystal to amorphous phase transition induced by ball — milling in pure Si and pure Ge powders. Based on X ray diffraction patterns, scanning and transmission electron micrographs, EDX microanalyses, differential thermal analyses and differential scanning calorimetry, it seems that amorphization occurs during the continuous decrease of the particle grain size and.

We discover that this guest retention is greatly enhanced upon facile amorphisation by ball milling, particularly in the case of ZIF‐mnIm, for which I 2 loss is retarded by as much as 200 C. It is anticipated that this general approach should be applicable to the wide range of available metal–organic framework‐type materials for the permanent storage of harmful guest species.
Calorimetric evidences indicate that during cryogenic temperature milling amorphization procedure is faster than that at ambient temperature. Our experimental results suggest that amorphization of the crystalline element selenium is driven by defects created by frequent mechanical deformation.

Apr 01, 2008 William G. Howard Jr., vertical machining center product line manager for Makino, wrote a book on hard milling—“High Speed, Hard Milling Solutions” from Hanser Gardner Publications. He also detailed the process of hard milling at a recent technology expo, which took place at Makino’s die mold headquarters in Auburn Hills, Michigan.
Feb 03, 2012 Touzik et al studied the structural transformations and amorphization of graphite upon high energy ball milling under argon and hydrogen atmosphere.Up to approximately 40 of the adsorbed nitrogen was stored in ultra micropores with diameter less than 0.8 nm and it was independent from milling atmosphere.
Jan 25, 2019 Titleist Pro V1 2019 Golf Ball Review. The Titleist Pro V1x is a four piece ball with 328 dimples and it is this different type of construction that delivers the alternative feel and performance to Pro V1. With my driver the 2019 Pro V1x is spinning about the same as its predecessor and about the same as the 2019 Pro V1.

Abstract. The effects of milling atmosphere and mechanical alloying (MA) duration on the effective lattice parameter, crystallite size, lattice strain, and amorphization rate of the W 0.5 wt. Ti powders were investigated. W 0.5 wt. Ti powders were mechanically alloyed (MA’d) for 10 h and 20 h in a high energy ball mill. over, morphology of the powders for various MA was analyzed using.
Dec 30, 2002 Ball milling the drugs alone for 48 h resulted in no amorphization. X‐ray powder diffractometry (XPD), birefringence, and differential scanning calorimetry (DSC) data indicated amorphization of all the four drugs on ball milling with Neusilin.

Amorphization by mechanical milling (MM), where a single composition (e.g. intermetallic compound) is milled requires the accumulation of defects to induce the transformation. It is concluded that anti site chemical disorder and nanocrystalline grain boundaries are the important defects in this regard.
