In this study, the effects of dry, liquid coolant and LN2-based cryogenic cooling applications on cutting temperatures at 50,100,150 m/s speeds 1,2,3 μm/dev feed rate were compared in micro-milling Ti6Al4V alloy . At different parameters, internal workpiece-cutting edges (wacec) zones are simulated observed. Cryogenic cooling, dry perceived that tool wear, chip formation, strain, stresses, shea...

Laser driven particle acceleration and measurements ofion energy loss in plasma largely rely on suitable targets toachieve good particle beam and plasma quality. Recent re-search results [2] indicate that cryogenic targets allow forvery high ion energies. Advantages of our cryogenic tar-gets include high purity at solid density in a self-supportedstructure as well as fit...

A Ni-rich Ni50.3Ti29.7Hf20 (at. %) high-temperature shape memory alloy was machined under different cooling conditions, specifically cryogenic and flood cooling, results were compared with those from dry machining. The effects of on machinability measures such as tool wear, cutting forces surface quality evaluated for various speeds. Microhardness, phase transformation temperatures latent heat ...

Current Process HVOF thermal spray is widely used for coating critical wear parts like landing gear, bearing races, valves and turbine components. Generally, fully or partially molten metal, composite, or ceramic droplets are propelled from a gun or torch onto the workpiece. Multiple passes are required to build up the coating, since each pass only deposits ~ 0.0002 in 0.0005 in thickness of ma...

Buffer gas cooling of molecules to cold and ultracold temperatures is a promising technique for realizing a host of scientific and technological opportunities. Unfortunately, experiments using cryogenic buffer gases have found that although the molecular motion and rotation are quickly cooled, the molecular vibration relaxes at impractically long timescales. Here, we theoretically explain the r...

We generalize the two-temperature model [Sanders and Walton, Phys. Rev. B 15, 1489 (1977)] for coupled phonon-magnon diffusion to include the effect of the concurrent magnetization flow, with a particular emphasis on the thermal consequence of the magnon flow driven by a nonuniform magnetic field. Working within the framework of the Boltzmann transport equation, we derive the constitutive equat...

We describe direct determination of the state of intracellular water, measurement of the intercellular concentration of a cryoprotectant agent (dimethylsulfoxide), and the distribution of organic material in frozen mammalian cells. Confocal Raman microspectroscopy was utilized at cryogenic temperatures with single live cells to conduct high spatial resolution measurements (350 × 350 × 700 nm), ...
