Among the physical quantities, cutting force and heat are the most essential one for cutting
process, which stands out to affect the whole cutting process seriously especially for difficult-to-cut
materials.
Work material: TC4 titanium.
Thus, tool material could remain certain red hardness on the basis of reducing strength of the workpiece material.

In addition, the application of photosensitive elements based on perovskites directly onto glass (or other materials) is much cheaper than methods for producing thin-film elements.
Dimethylformamide was chosen as the solvent, providing a true solution of the starting materials used.
When used as such transport layers (HTM) of organic materials such as SPIRO - OMETAD and PEDOT: PSS, it is not possible to achieve high stability and service life.
Therefore, an active search for the otherinorganic materials is currently underway.

Introduction
In recent years, nanocrystalline materials have attracted people’s great interests due to their excellent physical and mechanical properties, such as large volume fraction of grain boundaries, high hardness and strong wear resistance [1-10].
However, nanocrystalline materials are under a state of thermodynamic non-equilibrium, and show sensitivity to widely fluctuant temperature.
According to this view, it is meaningful to determine the suitable application temperature of nanocrystalline materials.

China Keywords: Silicon carbide, E1/E2, DLTS, positron lifetime spectroscopy Abstract E1/E2 (EC-0.36/0.44eV) are deep level donors generally found in ion-implanted, electron and neutron irradiated n-type 6H-SiC materials.
With focus to find the minimum energy for generating E1/E2, we have performed DLTS studies on n-type epi 6H-SiC materials irradiated by electrons with varying energies.
E1/E2 are the deep level donors (~0.36/0.44 eV below the conduction band) that are usually found in ion implanted and particle irradiated 6H-SiC materials.
E1/E2 are the deep donors that are commonly observed in particle irradiated or ion implanted n-type SiC materials.
