Skin-Core Scanning Strategy in LPBF Processed Ti6Al4V: Effects on Microstructure and Microhardness

CODEN: MPCACD

Abstract

The skin-core scanning strategy in the present study was employed to observe microstructural changes in laser powder bed fusion processed Ti6Al4V. The microstructural characterization was carried out using optical microscopy and microhardness tests were performed. The microstructural investigation indicated that the skin region had a 34 % smaller grain size than the core region, and the presence of α martensite needles. Because of the finer grains, the microhardness values were marginally higher on the skin than in the core region. The current study’s findings open a pathway to tailor functional and architectured microstructures with desired mechanical properties for end-use critical applications.
