Manufacture of Heavy Plate by Applying Direct Quenching

A novel monolithic microactuator fabricated by 3D rapid direct manufacture

In this paper we present the world’s first micropump entirely fabricated using a 3D direct manufacture process based on microstereolithography. The device employs a single pneumatically actuated membrane, with flow rectification provided by a nozzle/diffuser arrangement. A maximum flow rate of just over 2,000 μl/min was achieved with a pneumatic pressure of 2 PSIG and a stroke rate of 96 Hz. Th...

A Study on the Mechanical Properties of Dual Phase Steels Prepared by the Direct and Step Quenching Procedure

Two different dual phase steels were prepared from low carbon manganese steel after the elimination of the banding using the direct quenching (DQ) and the step quenching (SQ) procedures. Different heat treatments resulted in different martensite morphologies, microstructures and mechanical properties. The heat treatments were designed in such a way to obtain a 0.25 volume fraction of martensite...
