Thermodynamic Mechanism of Cryogenic Air Minimum Quantity Lubrication Grinding
The achievement of high-efficiency and precise grinding of difficult-to-cut metals-like titanium alloys-is essential in the aerospace industry. However, the process often results in thermal damage to the workpiece surface, posing a significant technical challenge. While minimum quantity lubrication (MQL) has been used to aid titanium alloy grinding, its effectiveness is limited by insufficient heat dissipation and lubrication. As an alternative to normal temperature air for carrying micro-lubricants, Cryogenic air has shown promise in improving oil film heat transfer and lubrication performance in the grinding zone, thus reducing workpiece surface thermal damage. The experimental state of the technology demands more comprehensive studies on its effectiveness and on the underlying mechanisms. Thermodynamic Mechanism of Cryogenic Air Minimum Quantity Lubrication Grinding addresses these challenges by providing a theoretical framework for understanding and optimizing cryogenic air minimum quantity lubrication in grinding processes, particularly for titanium alloys. It explores the physical characteristics of lubricants under cryogenic conditions, the influence of low temperatures on atomization effects, droplet formation dynamics, and heat transfer mechanisms within the grinding zone. By establishing quantitative relationships between cryogenic air parameters and lubricant properties, the book lays a foundation for enhancing the cooling lubrication mechanism of cryogenic air MQL in grinding processes. Researchers, scholars, and graduate students in universities and research institutes focusing on machining will find this book invaluable, as it goes beyond the theoretical insights into practical solutions to enhance grinding efficiency and reduce thermal damage.

Characteristics and Thermal Behavior of Sputtered Titanium Thin Films on Various Substrates
Titanium films are growing in popularity, and are soon expected to replace copper for metallization purposes. However, the thermal stress behavior of titanium films had not been extensively studied, and therefore not clearly understood. Thus, the main goal of this work was to develop a systematic process to analyze and model the d¿/dT evolution between 20ºC and 300ºC, in sputtered, titanium thin films. A biaxial stress state has been legitimately assumed. In the laboratory, titanium films, with a nominal thickness of 200 nm, were deposited on five different kinds of unheated substrates, by RF magnetron sputtering. These substrates included titanium plate, soda-lime glass and three kinds of p-type silicon wafers, having crystallographic orientations of (100), (110) and (111). X-ray diffraction was used to characterize the crystallographic evolution with respect to temperature. By utilizing a heating chamber and special tooling, the lattice spacings were measured in-situ, and the thermal stress behaviors were estimated with either the sin2¿ method or the d-spacing method.
