AUTOMATED SYSTEM FOR MEASURINGTHE PARAMETERS OF DIFFRACTION ON POLYMER FILMS WITH PERIODIC MICRORELIEF

RUDN Journal of Engineering Research, 2015
An automated system for measuring the diffraction efficiency of light, as well its kinematic scheme, were designed and assembled. The measurements of the diffraction efficiency of light on the sample of polymeric substrates with periodic microrelief were

Toward Architected Microstructures Using Advanced Laser Beam Shaping in Laser Powder Bed Fusion of Ti‐6Al‐4V

Advanced Functional Materials, EarlyView.
This research applies advanced laser beam shaping (LCoS‐SLM) to fabricate the Ti‐6Al‐4V alloy via laser powder bed fusion. A tailored beam is used to prevent martensite formation and create a dual α+β microstructure by controlling cooling rates.
