Study on processing and strengthening mechanisms of mild steel subjected to laser cavitation peening
TL;DR: In this paper, a method of laser cavitation peening (LCP) was employed to strengthen the Q235 steel by causing plastic deformation in the surface layer of material and thereby introducing compressive residual stress and enhancing the microhardness.

Degradation of Rhodamine B in aqueous solution by laser cavitation
TL;DR: Experimental results indicate that RhB aqueous solution can be degraded effectively by LC and the degradation follows the pseudo-first-order kinetics, which is more energy efficient at lower laser energy.

Bubble dynamic evolution, material strengthening and chemical effect induced by laser cavitation peening
TL;DR: The results found that the pressure intensity of shock wave and water-jet decreases with increasing the γ, and the enhancement of microhardness and the residual stress increases with the increase of γ.

Study on transient characteristics and influencing of temperature on cavitation bubbles in various environments
TL;DR: In this article, the authors studied different dynamic characteristics of cavitation bubbles in infinite domain and attached to a solid wall and proposed an approximate linear relation to describe the relationship between the maximum bubble diameter and the ambient temperature.
