In this investigation, attention is directed to the phases covered by a 28 per cent tin alloy. When the investigation was started, consideration was given to the possibility of making a Time - Temperature - Transformation curve for this parti­cular alloy. As the work progressed and further research was carried on, this phase of the work was abandoned.

In the modern aspect of powder metallurgy, the first use of a sintering process was in making filaments for incandescent electric lamps.In the short while from the day of Edison to the pres­ent, the science of working with metal powders has advanced by leaps and bounds.

The field of archaeology and that of metallurgy appear to be widely separated and in no way related. Work done in recent years, however, tends to show that, in many ways, the metallurgist can supplement and enhance the information gain­ed by the archaeologist, at least in regard to those objects which have been made of metal.

Among the many aluminum alloys which have been studied are the binary copper-aluminum alloys. These have proven to be among the most useful of the alumi­num alloys thus far worked upon.

Manganese has been successfully electrodeposited from aqueous solutions in past years by several work­ers in electrochemical and electrometallurgical fields. The present work was concerned, primarily, with investigation of electrodeposition from solutions which are commercially obtainable from the hydrometallurgical or pyrometallurgical treatment of the low grade mangan­ese deposits of this country.

In 1947, out of the 100,000 long tons of tin con­sumed in the United States, 25,000 tons went into solder. Tin plate took 39,000 tons while babbit, bronze and coll­apsible tubes accounted for approximately 17,000 tons. Solder ranked second to tin plate and required more than the next three major uses combined.
