Structure of Eutectics

The present paper is a result of work done on the study of structures of eutectics of a certain eutectic-forming binary systems. In this research work no systems with intermetallic compounds have been studied.

Some Investigations on Quantitative Measurement of Amalgamation

Amalgamation is a process in which precious metals are collected by mercury. The exact way in which the mercury holds the other metals is not positively known. It is proba­ble that a series of intermetallic compounds form. Very little work has been done so far on the theory of amalgama­tion.

An Investigation of the Age-Hardening of Copper with Nickel-Boron Compounds

Boron is an element whose metallurgical possibil­ities have never been fully investigated. The principal reason for this fact seems to lie in the difficulties encountered in preparing elemental boron and its various intermetallic compounds.
