Shell material for the discharge high-pressure lamps: Sapphire. Gavrish S. V., Loguinov V. V. P. 5—9.

A new material — monocrystalline aluminium oxide (sapphire), which is used as a discharge lamp shell, is under consideration in the article. Advantages of the sapphire are shown, such factors as imperfection of a crystal, its machining and heat treatment, de­termining its optical transmission, radioimmunity, ultraviolet radi­ation resistance and critical electrical load per discharge tube surface unit are covered.

Heat treatment effect on the welds' structure and proper­ties of pressed-and-welded components from steel 10F2OBK). Botvinnikov A. Yu., Neifeld O. I., Yefimenko L. A., Kapoostin O.Ye. P. 10—12.

Research results of the welding procedure and afterbaking effect on the structure and properties of the welded tee-joints from the steel 10T2OEK) are given.

Analysis of the standard constructions' shapes and of cut process flowsheets of the rotary bodies. Tarasov A. B., Tara-sovS. A. P. 13—18.

Cut process flowsheets of the axisymmetric turned construc­tions, consisting of three figures, are described. Weight and mo­ment errors calculation formulae taking into account dimensional accuracy of each figure, constituent of the axisymmetric con­struction, are considered. It is established that choice of the con­structions' shapes must ensure conditions under which inertia moment values' spread is minimal.

Study of the vibroacoustic radiation at hard turning. Rogov V. A., Kozochkin M. P., Popikov A. N. P. 18—21.

Research results of vibroacoustic signal at rigid turning at the moment of penetration into the workpiece and further processing are given, as well as of surface roughness changes depending on the material used and on the construction of the support blade in the fastener assembly of the cutter plate.

Effectiveness increase of the abrasive band grinding process. Guinergart O. Yu., Popov A. Yu. P. 21—22.

Abrasive-band grind process advantages and special features of the turbine blades from the heat-resistant and titanium alloys are covered. Recommendations are given on the abrasive band dressing by blunted granular surface layer fracture forming sharp edges. A special facility allowing for abrasive band dressing and reusing is offered to improve cutting power of the abrasive belt.

Electroarc surface process of the tool steel for burnishers. Gurevich Yu. G., Marfitsyn V. V. P. 23—25.

Steel parts electroarc surface process by white iron layer ap­plication on their surface using contact building-up, allowing for forming tight, porousless antiwear coating is considered.

Linear friction welding. Shtrikman M. M. P. 26—31.

Basic stages of joint formation by linear friction welding (LFW) are considered. Foreign authors' working data on LFW equip­ment designing, on studying conditions of qualitative joining ob­taining and LFW process industrial application examples at weld­ing design production, mainly at air engine blades, are described.

Magnetoimpulse driven percussion electrostatic welding. Strizhakov Ye. L., Neskromny S. V., Merkulov R. V. P. 32—34.

An essentially new shot welding practice using magnetic pres­sure as forging force is suggested. This allows for warming-up and severe deformation of the jointed surfaces. The essence of the process and its advantages are described; research results are covered.

Combined application of the low-frequency vibration and vortex cavitations in liquid containing nanoabrasive powders at machine components turboabrasive machining. Ivanaysky A. V., Ivanaysky V. A., Koval Yu. I. P. 35—36.

A Process of machine components turboabrasive machining in cavitating lubricoolant containing abrasive granular, allowing for eliminating dusting possibility due to seal upset of the pneu­matic turboabrasive plants when in operating process is described, as well as for improving parts' quality and for processing ecolog­ical compatibility increase.

Welds' high-temperature stability of the steampipe with imperfection in weld metal. Part 1: Test results of the faulty samples. Khromchenko F. A., Fedoseyenko A. V. P. 44—46.

It is established that standard durability of the welds from steel 12X1ÌÔ at 545°C for expected base of 105—3 • 105 hours is ensured in case maximal depth of technological defect is lim­ited by 4 mm in the weld metal 09X1ÌÔ.
