source data for "The Effect of In Situ Heat Treatment on the Microstructure and Mechanical Properties of H13 Tool Steel Specimens Produced by Laser-Engineered Net Shaping (LENS®)

The uploaded files comprise the source dataset for a paper focusing on samples preparation of H13 tool steel by the LENS® laser addtive manufacturing technique.

Below is a list of the research techniques used and the results obtained with them: 

X-ray phase analysis - performed with a Rigaku Ultima IV diffractometer equipped with a cobalt anode lamp and parallel beam geometry. 

Microscopic analysis - performed with an ECLYPSE NA200 (Nikon Inc., Melville, NY, USA) digital microscope, a Hitachi SU8000 (Hitachi High Technologies company, Krefeld, Germany) scanning electron microscope and a Quanta 3D FEG DualBeam scanning electron microscope (FEI Quanta 3D, Hillsboro, OR, USA) scanning electron microscope. 

Mechanical properties - hardness measurements were performed with a Brinell–Vickers HPO-250 universal hardness tester, a tensile tests were performed with an Instron 8501 universal testing machine, and an impact test was performed with a Wolpert/Instron PW30 impact hammer.
