Selective laser melting of dispersed TiC particles strengthened 316L stainless steel
, 2020316L austenitic stainless steel has a wide range of industrial applications. However, one of the major drawbacks is its low yield strength (170–300 MPa in annealed state).

Objectives: To describe two patients with tics status, propose a definition of this syndrome and draw attention to its clinical significance. Method: Two patients suffering from Tourette's Syndrome who had developed episodes of continual motor tics that lasted from minutes to hours, were non-suppressible and intruded into normal functioning, were ...
