With increase in ballmilling time, the formation of titanium nitrides became evident. From the diffraction pattern of the sample milled for 96 h (Fig. 2b), peaks of Ti nitrides could be clearly majority of nitrides observed at this stage were Ti 2 N, while a small fraction was TiN. It is interesting to note that the intermediate phase of Ti 2 N could not be observed in solid ...

P4 mill was used to check the repeatability of the reactive ball milling between titanium and urea. On the other side, it is used to check whether the reactive ball milling time can be reduced by improving the rotational speed. The XRD pattern of the powders milled for 30 h from P4 mill is shown in Fig. 2. The fully developed structure of TiN ...

Titanium can turn the slightest weakness into poor tool life and unpredictable processes, so the right work holding, tool holding and programming have big roles. Be sure to use the right amount and type of cutting fluid. A watersoluble oil or semisynthetic fluid provides the best mix of lubricity and heat removal.

Amorphization of metallic titanium by ball milling was presented. With the introduction of continuous pickup of impurities, hexagonally closepacked (hcp) titanium transformed gradually into an amorphous phase without experiencing any intermediate stage of forming a detectable metastable compound phase. The crystallization temperature of the obtained Ti metal glassy phase is about 640 K. The ...

Titanium and carbon powder mixtures with compositions of Ti100−x C x (x = 50, 40, 30) were milled under a helium atmosphere using a magneto ball mill. Controlled ball milling was performed in a higher energy impact mode and a lower energy shearing mode. For Ti50C50 and Ti60C40 powder mixtures milled in impact mode, TiC was formed via a mechanicallyinduced selfpropagating reaction (MSR ...

In order to quantify the rate at which hydrogen is absorbed for different milling conditions we define the mean hydrogenation time, t m, as the time required for the sample to absorb one hydrogen per titanium atom. Fig. 3 shows t m as a function of balltosample weight ratio. The data shown here clearly indicate the differences between one ball and two balls in terms of milling efficiency.
