... microstructures exhibited interdendritic regions separated by alumina particles as well as primary aluminum dendrites and eutectic silicon. The distribution of alumina particles in aluminum alloy plays a vital role in grain refining and modifications of the eutectic morphology [ 20 ]. The more uniform particle...

...Jiaqing Wu; Weilong Cong; Robert E. Williams; Z. J. Pei Rotary ultrasonic machining (RUM) is a hybrid machining approach that combines two material removal mechanisms, namely, diamond grinding and ultrasonic machining. This paper presents the results of dynamic process modeling for RUM of alumina...

...B. S. Yilbas; S. S. Akhtar; C. Karatas Laser cutting of small diameter holes in alumina tiles is carried out. Temperature and stress fields are predicted numerically using the ABAQUS finite element code. The cut sections are examined by incorporating scanning electron microscope and optical...

...J. Harris; R. Akarapu; A. E. Segall Despite the many advantages of using lasers for welding ceramics (alumina in particular), cracks induced by the resulting and severe thermal stresses are often detrimental to weld quality and strength. While many factors contribute to the formation...

...John E. Wentz; Shiv G. Kapoor; Richard E. DeVor; N. Rajagopalan The recycling of semisynthetic metalworking fluids (MWFs) using alumina membranes is significantly impacted by aggregated MWF microemulsions that cause partial and complete blocking of membrane pores. In this paper, computational fluid...

...John E. Wentz; Shiv G. Kapoor; Richard E. DeVor; N. Rajagopalan In this paper, the fouling of sintered α -alumina membranes by an uncontaminated semisynthetic metalworking fluid (MWF) is addressed. Experimental evidence of the form of flux reduction curves, scanning electron microscope images...

... experiments designed by the model are successfully conducted on silicon nitride ceramics using TiAlN coated carbide end mills and Inconel 718 using SiC reinforced alumina cutting tools. The promising experimental results, including good surface roughness and acceptable tool wear, show the validation...

... such as C O 2 beam diameter, incident power density, positioning of the laser with respect to cut, as well as timing were then studied with respect to the goal of reducing and/or delaying the likelihood of fracture. 26 07 2005 02 03 2006 laser beam cutting alumina bending fracture...

...Takashi Ueda; Akira Hosokawa; Keiji Yamada In this paper, the influence of oil mist on the tool temperature in cutting is investigated experimentally. The turning of a carbon steel with oil mist applied is performed, and the temperature of the alumina tool at the tool-chip interface is measured...
