DOI: 10.1007/s11665-020-04844-4
Abstract: Low-cycle fatigue and creep-fatigue tests were conducted at 815 °C on laser-welded, selective laser melted (SLM) Inconel 625 test specimens. The results showed that the microstructure of the welding zone was mainly composed of columnar dendrites,… read more here.

DOI: 10.3390/ma16113913
Abstract: Polymer-matrix composites are widely used in engineering applications. Yet, environmental factors impact their macroscale fatigue and creep performances significantly, owing to several mechanisms acting at the microstructure level. Herein, we analyse the effects of water… read more here.
