120 SUMMARY OF CUlUiEKT RESEARCHES. 



KoNST ANiNOFF, N., & W. SMIRNOFF — Alloys of Tin and Antimony. 



[The composition of the phases present in the solid alloys has beeu ascer- 

 tained by thermal analysis and a study of electrical properties. The 

 compounds occurring are SnSb, and SnjSb.,.]

[Piping is regarded as a consequence of the contraction occurring when the 

 liquid passes to the solid state.]

Primeose, J. S. G. — MicrograpMc Examination of Failures. 



[The microscopical investigation of cases of failure in wrought iron, mild 

 steel, rail steel, cast iron, and other materials, is described and illustrated 

 with photomicrographs.] Engineering, xcii. (1911) pp. 748-50 (15 figs.).

 Temperature, and the variation of the Magnetic Transformation Point with 

 the Field. Arch. Sci. Phys. Nat. Geneva, xxxii. (1911) pp. 315-37 (11 figs.).

 affected by change of temperature.]

[Characteristic veins and cracks were observed in the ferrite grains of 

 samples of open-hearth steel taken from the bath before deoxidation.]

Thomsen, K.— Solubility of Graphite in Solid Iron, and Melting Phenomena in 

 Orey Cast Iron. 



[The limits of solubility of graphite in iron at various temperatures have 

 been determined. The equilibrium of the two systems, iron-graphite 

 and iron-cementite, is considered.]

[An equilibrium diagram for the range to 18 p.c. in the iron-carbon system 



is given, based on a study of the alloys containing up to 24 p.c. carbon.]
