Abstract

The aim of this work is to develop a table top rapid quenching metal powder generator as a fundamental tool for the laboratory scientist permitting the development of new alloy compositions. The table top generator utilizes electrohydrodynamic (EHD) processes to generate the powder with a goal to produce more than 20 grams/day at cooling rates exceeding 105K/sec for use as a laboratory research tool. The advantages of the process lie in it being a continuous process, having no vital moving parts, and can include radiation, convection and splat cooling techniques. The initial accomplishment was a demonstration of the feasibility of utilizing EHD, in the production of a wide range of powder sizes and corresponding cooling rates.
