METALLURGICAL DEVELOPMENTS IN STEAM POWER PLANT

As a member of American Metallurgists Delegation, Dr. R. I. Jaffee, 1978President of the Metallurgical Society of AIME, delivered an interesting lecture en-titled "Metallurgical Developments in Steam Power Plant" in Beijing on Novem-ber 13, 1978. The lecture contains (1) development of steam power plant and itsrelated metallurgical problems, (2) titanium alloy blades for final stages of lowpressure steam turbine and (3) massive forgings of turbine rotor and generator.Wehave great pleasure to publish this paper for which Dr. R. I. Jaffee readily agreed.It is hoped that the publication of this paper in Acta Metallurgica Sinica will pro-mote and strengthen scientific intercourse between the Chinese and American me-tallurgists.
