Tire Wear and Fuel Consumption. H. C. J. de Decker, G. J. Van Amerongen, and J. F. Benders. Rubber Chemistry and Technology, v. zg,Oct.-Dec. 1956, p. 1445-1457. (From Kautschuk zend Gunami, v. 8, Sept. 1955. p. 21-26.) Measurements show that GR-S tires are advantageous only in a tropical climate. In all

ANALYSIS
Surface Structures
Images d’&hantillons mitalliques contraints obtenues au microscope a photo&nission. Images of Strained Metal Samples, Obtained With the Photoemission iMicroscope. R. Bernard, C. Guillaud, and R. Goutte. Journal de Physique et le Radium, v. 18, May I9571 p. 327-330. Studies with Au samples show an increased in areas of maximum strain brightness (breaking zone), probably due to a local increase of the photoelectric emission factor. Identification of Minute Amounts of Metals and Alloys by Efectrosolution and Electrophoresis. Charlotte L. Brown and Paul L. Kirk. Mikrochimica Acta, 1956, no. II, p. 15931599. A scheme

Relation of depth of propagation of plastic deformations in steel and brass to rate of machining and feed; distortions of second and third order. Chemical Analysis of Surface Layers of Metals Exposed to Various Tvues ,_ of Wear. (in Russian) B. I. Kostetskii, N. L. Golego, and P. K. Topekha. Vestnik Mashinostroeniia, v.36, no. IO, Oct. 1956, p. 25-26. The role of 0 in the hard, white surface formations of steel exposed to certain friction conditions. How to Reveal the Microstructure of NonEtching Surface Layers on Ferrous Metals. B. A. Krasyuk. Hewy Brutcher Translation Aro.3920,6pp. (FromZavodskaiaLaboratoviia, v. zz, no. 5,1956, p. 556-558.)

Temperature Affects Euglne Valve Wear. Max J. Tauschek. SA E faunaal, v. 65, July 19.57. P. 53-54. The characteristic heat pattern and its control.
AND

A study of failure of known etchants to bring out the structure of surface layers of ferrous metal which have been subjected to surface treatment.
Analyzing the Textures of Rolled Aluminum. (in Spanish) Jose Terraza Martorell and Juliana Arroyo Ruiperez. Instituto de1 Hierro y de1 Acero, “. IO, Jan.-Mar. 1957, p. 20-35. A photometric study of rolled Al diffractograms by means of different micronhotometers. Textures for various degrees of reduction Variation of the polar figures. The Nature of Mechanically Polished Metal Surfaces: The Surface Deformation Pro+ duced by the Abrasion and Polishing of 70: 30 Brass. I.. E. Samuels. Institute of Metals, Journal, v. 85. Oct. 1956, p. 51-62 + 4 plates. Certain principles are established for methods by which surfaces free from serious strains may be produced by mechanical methods of polishing. Structure suggests that fine metallographic polishing operations occur essentially by a cutting mechanism. X-Ray Study of the Quality of the Surface ou Finely Ground and Machined Metals. (in Russian) Iu. S. Terminasov, A. G. Iakhontov, and A. V. Poltavskii. Izuestiia Akademii Nauk SSSR, Seriia Fizicheskaia, v. 20, no. 6, June 1956, p. 689-692. Parallels in structural changes and microhardness between a finely-machined surface and the surface produced by grinding-polishing. Dislocations and distortions in lattice and reduction in size and deformation. Absolute Areas of Some Metallic Surfaces. Thomas L. O’Connor and Herbert H. Uhlig. Journal of Physical Chemistry, v. 61. Apr. ‘9.57, P. 402-405. Roughness factors were calculated for abraded iron foil and 18-8 stainless steel under various circumstances with ethane as adsorbate at --I 83’C.
