Abstract
- The paper investigates the influence of gas dynamic cold spraying followed by laser processing of stainless steel samples on their dynamic (spallation) strength under the impact load at a 105 s–1 strain rate. The impact velocity effect on the microstructure and dynamic strength is studied herein. It is shown that the dynamic strength of steel samples after laser processing remains unchanged compared to unprocessed samples. Amorphization and melting are observed in the spallation region of the processed samples. Intense mechanical twinning develops inside austenite grains after the load application, and a largest number of twins is observed in unprocessed samples. [ABSTRACT FROM AUTHOR]
