Thermal state of a porous plate cooled by strong injection during radiative - convective heating

Experiments and calculations have revealed the characteristics of internal cooling of a porous plate by strong injection during radiative-convective heating.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 23, No. 5, pp. 792–800, November, 1972.     

A cryogenic flange connection

The design and technical characteristics of a tight cryogenic seal are described; in the temperature range from 20 to 300 K and at pressures up to 10 bar the flow across it is not above 1 × 10^?9/torrs^?1.     

Some data on the infiltration of porous iron-manganese alloys with copper and its alloys

Summary It is clearly shown that nonporous iron-manganese-copper alloys can be produced by infiltrating an iron-manganese matrix with copper or copper alloys.Additional data have been obtained on the effectiveness of copper, a copper-manganese master alloy, and brass as infiltrating materials; the feasibility of producing a nonporous iron-manganese alloy free from oxide inclusions is demonstrated.Data are presented on the formation of iron-manganese-copper alloys with different manganese contents during infiltration with copper and copper-manganese master alloys, under different infiltration conditions.The extent of phase interaction during infiltration and the condition of boundaries in alloys produced under different infiltration conditions have been investigated.
