Investigating the Effect of Inclination Angle and the Influence of Scan Parameters on the Appearance and Thermal and Mechanical Properties of Filigree Tension Rods of LPBF‐Manufactured NiTi Shape‐Memory Alloys

Advanced Engineering Materials, EarlyView.
This article investigates the dependence of the properties on the manufacturing orientation in the form of the inclination angle to the build plate of LPBF‐fabricated NiTi rods with a diameter of 150–220 µm. Metallographic, chemical, thermal, and mechanical characterization show behavior under identical manufacturing conditions that ranges from ...

Experimental study of fracture surface roughness on rocks with crack velocity

Physical Review E, 1996
In this paper we address the question of the influence of crack velocity on the fractured surface roughness. We studied samples made of Berea sandstone, chosen for their good macroscopic homogeneity and their granular microstructure. The samples were fractured in a double cantilever geometry, which allowed for a controlled crack speed that was ...
