Although an application of ML materials has not been commercialized due to their relatively short emission period, yet they are expected to be used as the novel nondestructive techniques for damage detections, modern visual force/stress sensor or structural health monitoring systems [14, 15].
Due to the fact that an electron-hole recombination contributes to the light emission in luminescent materials [32], the number of photons emitted within deformed domains should be proportional to the change in number of conducting electrons.

Molecular dynamics (MD) simulations of nanometric scratching with diamond tip are conducted on single crystal copper crystal plane (010), and MD simulations are carried out to investigate the mechanism of material removal and the generation of defects on the surface, subsurface and inner of material.
Ye [12] performed MD simulations of the nanometric cutting of single-crystal copper with the EAM to analyze the nature of material removal, chip formation, material defects and frictional forces.
The initial atomic configuration of the workpiece material is created from the face-centred cubic (FCC) copper lattice.

However in this two-liquid casting method, heat removal occur not only the interface of alloy but also the inside of the bulk material by heat transfer between droplets has higher and lower liquidus temperature.
Therefore even in large scale applications, it is possible to achieve undercooling effect at the inside of bulk material.
Two sets of experiments were carried out for the same materials under the similar quench condition.
The materials are mixture of 50 wt % pure Sn and 50 wt % Sn60Pb40 alloy.

Research on the simulation and calculation of the temperature field of friction plate in brake is one of the main references for constructing a frictional material couple.
Research on the simulation and calculation of the temperature field of friction plate in brake is one of the main references for constructing a frictional material couple.
For analyzing the temperature field conveniently, it is assumed that: (1) the friction heat flux transfers along the axial and radial direction; (2) the coefficient of friction remains constant during braking; (3) the brake pressure is uniformly distributed over the contact area of the plate and mating plates; (4) the materials of the friction plate are homogeneous and their thermal properties are invariant with temperature; (5) the thermal properties of lubricant oil are invariant with temperature; (6) the temperature field is consecutive and heat flux is constant; (7) the radiation is omitted.

Monel 400 is one of the widely used high temperature material that can obviate the problems.
Experimental work The base material employed in the study was Monel 400 and its chemical composition include Ni 65.38, Cu 30.25, Fe 2.11, Mn 1.07, Si 0.4 and C 0.1 by weight.
Since the composition of base material and filler material are same, they readily take into solution of nickel, copper and iron by dilution from the parent metal.
