National Institute of Standards and Technology, Gaithersburg, MD 20899-0001 This paper presents the results of heat flux sensor calibrations in two blackbody facilities: the 25 mm variable temperature blackbody (VTBB) primary facility and a recently developed 51 mm aperture spherical blackbody (SPBB) facility. Three Schmidt-Boelter gages and a Gardon gage were calibrated with reference to an el...

T next article in our series is a case report written in 1848 by John M. Harlow, M.D., describing his care of Mr. Phineas Gage, who suffered an extreme injury to the frontal cortex. Mr. Gage was employed as a railroad worker in Vermont and fell victim to a freak accident that involved a long metal rod called a tamping iron. This rod was used to pack sand over an explosive charge, which was used...

The complex solidification dynamics and thermal cycling during Selective Laser Melting process is expected to result in non-equilibrium material characteristics. There is an essential need for characterization techniques which are critical towards the estimation of anisotropies. The current investigation is targeted towards establishing tensile testing methodologies and their relation to differ...
