Abstract

A method is described for the preparation of Charpy impact specimens suitable for screening purposes for a series of small experimental cast austenitic manganese steel heats. The process involves the investment casting of test specimens and notching by means of a computer controlled electrical-discharge-machining (EDM) unit.

Keywords:
impact tests, investment castings, austenitic manganese steels
