“…For example, ultrasonic shot peening (USSP), sometimes called surface mechanical attrition (SMAT) [4][5][6][7][8][9][10][11][12][13] uses a dynamic generator at frequencies ranging from 50 Hz to 20 kHz, to resonate peening media against a sample surface. Air blast shot peening employs compressed air to accelerate shots, and is widely used industrially because of its simplicity, low cost and applicability to variety of targets.…”

Experimental assessment and simulation of surface nanocrystallization by severe shot peening

Surface nanocrystallization is an effective approach to bypass the difficulties of synthesizing bulk nanocrystalline material and yet exploit its unique advantages in service. This study uses air blast shot peening over a wide range of coverage (peening time), from conventional to severe, to generate nanostructured surface layers on high strength low alloy steel. Electron microscopy observations were carried out to systematically study the degree and the mechanism of grain refinement as the severity of deformation increases. A model linking finite element simulation of severe shot peening to dislocation density evolution due to the accumulated plastic strain was developed to predict the resultant grain/cell size gradient in the surface layers. The proposed framework establishes a physical connection from processing parameters such as media size, velocity and peening coverage to the resultant structure, opening the possibility of designing a severe surface peening process to achieve a desired nanostructure.

“…The density is an essential macroscopic parameter to characterize the structure of glass. As network modifiers, rare earth metal ions filled space in glass network [25]. Y 3+ ions possess smaller radius, high filed strength and large coordination number, which attract the neighbor anion groups and make the glass structure more compact as the degree of polymerization reduces.…”

“…Rare earth oxides have a remarkable impact upon the structure and performance in silicate glass systems. Hence, in order to improve some properties of alkali-free aluminoborosilicate glass, rare earth oxides, as network modifiers, are usually regarded as effective additives [7][8][9][10][11][12][13][14][15][16][17]. Gao et al [18] found that the substitution of Y 2 O 3 for Al 2 O 3 showed a strong effect on the structure and properties of alkali-free aluminoborosilicate glasses.…”

Alkali-free aluminoborosilicate glasses were prepared by the conventional melting method. The effect of the replacement of CaO by La 2 O 3 on the structure, thermal, and dielectric properties of the glasses was investigated by FTIR, DSC, with thermal expansion instruments, and an impedance analyser. With increasing ratios of La 2 O 3 to CaO, the densities of the glasses increased linearly from 2.458 to 2.627 g•cm -3 . Meanwhile, the polymerisation degree of the glass network increased first and then decreased. The glass transition temperature, crystallisation onset temperature and expansion softening temperature showed a gradually increasing trend, while the thermal stability firstly deteriorated, then gradually improved. Additionally, the coefficient of thermal expansion (CTE), dielectric constant and dielectric loss initially decreased, followed by an increase. The sample with the La 2 O 3 /CaO ratio of 1.00 showed excellent properties: had a low CTE (2.71 × 10 -6 °C-1 ), had a dielectric constant (5.23), and a dielectric loss (1.12 × 10 -3 ), which means it is a promising material for integrated circuit packaging applications.
