Price et al. investigated aluminum particles as an additive to increase the thrust and Isp of the solid rockets. [3] Analytic study of aluminum particle combustion including radiation effect was conducted by Bidabadi et al. [4,5] Perturbation technique were used to obtain exact solution of sets of ordinary differential equations.
Recently Sundaram et al. [7] conducted similar study on nano-sized particles.
Risha et al. [9,10] implemented experimental studies on nano aluminum combustion with water.
Ignition temperature of nano aluminum particle which depends on the size of the particle proposed by Sundaram et al. [7] In Eqn.3, is density of water, is vaporization enthalpy of water.

Siddharth et al. [11] synthesised Al alloy A7075 with 5% RHA by stir casting.
Shivaprakash et al. [12] developed a hybrid composite with Al alloy with Cu (4.5%) matrix having SiC and RHA as reinforcements by stir casting.
They tested mass ratios of RHA:Al(OH)3 of 70:30 to 99:1.

Rusnaldy et al. [2] found that higher forces per unit area were needed to achieve ductile cutting mode.
Fang et al. [5] found that ductile cutting could be achieved with a negative effective rake angle cutting tool if the undeformed chip thickness was smaller than a critical value.
Foy et al. [6] indicated that with the application of the high hydrostatic pressure brittle materials could deform plastically, in turn producing continuous chips.
A Nakanishi AL-0201 airline kit provided the clean cooling air for the main spindle.
