The factors influencing the hardness would be: (a) the type of the crystalline phases, (b) the magnitude, size, and distribution of the crystalline phases, (c) the casting defects, such as pore, inclusion, and at el.
However, the HRC hardness of Cu65Zr25Ti10 is less than that of Cu60Zr30Ti10 alloy, indicating that the HRC hardness of materials is related not only with the type of phases but also with other factors, such as the microstructure, defect, and et al.

The construction of ellipsometer has been done several times, such as Hassani et al. (2017) [7] designing ellipsometer using single wavelength for the thin film characterization of silica, magnesium Florida and sulfide.

Venkatraman el al. proposed a geometric constrained optimization method considering the intersection points of the TOA measurement circles [5], and they further defined the closet position to these points as the MS's true location.
Greenstein et al. suggests that [10], where T1 is the median value of at d = 1km and d is the distance between the ith BS and MS in kilometers, is a constant (we choose 0.5) and is a lognormal random variable with (we choose =4dB).

Hendriko et al. [9] proposed an hybrid method in defining CWE between flat-end tool and free-form workpiece surfaces.
Another study for obtaining CWE of toroidal cutter during semi finish milling was also proposed by Hendriko et al. [10-12].
