ABSTRACT The nacrite-LiCl hybrid composite material was prepared at room temperature by indirect inter-calation of lithium chloride between the planar layers of nacrite, a clay mineral, using acetone as a solvent. The structural identification of the hybrid clay material was determined by means of X-ray diffraction (XRD), thermogravimetric analysis (TGA) and infrared spectroscopy (IR). The qualitative XRD analysis showed that the basal spacing value increased from 0.72 nm to 1.14 nm and revealed that the alkali halide intercalated successfully in the interlayer space of the nacrite...

ABSTRACT A composite material as a work piece is taken into account to investigate the elastic characteristics displaying during the cutting process. The magnitude of the elastic behaviors such as displacements and stresses reacts sensitively to the cutting angle and the vertical force increase, and the magnitude increases along the increments of the cutting angle and the vertical fo...
