“…The appearance of the (003) diffraction spots in 6H-SiC and the (200) diffraction spots in 3C-SiC is attributed to the existence of superlattice, since they should not exist because of the extinction in the diamond cubic structure. The 3C-SiC node grows along the [111] direction, which is the same with the longitudinal direction of the nanochains [23]. It is the general case for β-SiC to grow along the [111] direction, because of the low energy of the (111) planes.…”

“…A quantity of isopropanol equal to 1% of the total mass of the particles was also transferred into the pot to prevent clumping and coarsening. 14) A total of 72 milling cycles was performed, with each cycle consisting of 5 minutes milling followed by a 15 minutes pause.…”

The effect of the intermetallic compound layer formed by atmospheric controlled induction heating fine particle peening (AIH-FPP) treatment on the wear resistance and high-temperature oxidation resistance of titanium alloy was investigated. To form an intermetallic compound layer on a titanium alloy by AIH-FPP treatment, pure titanium, aluminum and nickel particles were mechanically milled using a planetary ball mill, and the prepared particles were used as shot particles in the AIH-FPP treatment. The results showed that intermetallic compound layers, consisted of Ti 3 Al and Ti 2 NiAl 3 , were formed on titanium alloy by AIH-FPP treatment using the prepared particles. The wear resistance and high-temperature oxidation resistance of the AIH-FPP treated specimen were higher than those of the untreated ones.

“…However, the TiAl alloys produced in this way generally have very coarse grain. Alternatively, the AlTi alloy can be prepared by powder metallurgy, particularly by mechanical alloying, which readily ensures structural refinement and chemical homogeneity [5][6][7][8].…”

Particle size and hardness of Al-10%wt.Ti powders due to the influence of ball diameter have been carried out using mechanical alloying techniques. The milling device used consisted of a Fritsch Pulverisette-5 planetary type ball mill with the rotational speed of about 360 rpm and balls size of 10, 15 and 20 mm. The materials used are stearic acid which was used as a process control agent, aluminum and titanium powders. A mixture of aluminum and titanium powders has the composition of Al-10wt.%Ti. The Al-10wt.%Ti powders, stearic acid and stainless-steel balls were added to the Fritsch Pulverisette-5 planetary in the argon gas environment. The weight ratio of stainless steel balls to the Al-10wt.%Ti powder was 20 : 1. The mixing time process was carried out for 5, 10, 15, 20 and 30 hours, respectively. Changes in phase compositions of these Al-Ti powders under different ball mill sizes were examined by XRD, and the optimum experimental parameter was obtained: the ball mill size was 20 mm. It was found that from the diffraction patterns of the Al-10wt.%Ti powders, the peaks of titanium begin to disappear with the increasing of the milling time, which indicates the increasing degrees of alloying of titanium atoms in the aluminum matrix. The microhardness test results showed that the hardness increases with increasing ball size.
