Degradation Mechanisms of Copper and Copper Alloys
… for dealloying and intergranular attack of Monel 400, a Ni-Cu alloy used as a steam generator tubing material, is proposed. Dealloying of Monel is contingent on the accumulation of Cu2+, which stabilizes metallic copper. This is achieved in the nuclear steam generator by accumulation of …

The use of magnesium-alloy tubing in heat exchangers
… by silicone-coated magnesium-alloy, aluminum, monel and stainless steel when used as heat exchanger tubes. Two single pass, double pipe heat exchangers were constructed using pyrex glass tubes as outer shells. The pyrex tubes were two inches inside diameter, 2.25 inches outside diameter, five …

Design, fabrication, and characterization of a multi-condenser loop heat pipe
… were fabricated using photo-chemically etched Monel frames with Monel sintered wicks with particle sizes up to 44 pm. The performance of the condensers was characterized in a custom experimental flow rig that monitored the pressure and temperatures of the vapor and liquid. Two condensers …

Preparation of Phenylsulphur Chloride Tetrafluoride
… Chlorination of a C6H5SF3-CSF mixture in monel at 220°C yielded a yellow liquid tentatively identified as a mixture of the new species C6H5SF4C1, FC6H4SF4C1 and C1C6H4SF4C1.

A study of effects of inhibitors on cathode potentials of metals in dilute acids
… electrode. Platinum, mild steel, copper, monel, inconel, yellow brass, nickel and tin were used as cathodic specimen electrodes. Platinum was also used as the anode. Four point nine per cent sulfuric acid, five per cent acetic acid and five per cent phosphoric acid were used as …

Breeding potentialities of the gray squirrel at Blacksburg, Virginia
… constructed for use throughout the study. The Monel, size I, fish tag was used for tagging the ear of the squirrel. The original handling techniques were patterned from those used by previous investigators, however, shortly after the project was begun a squirrel funnel, made of tightly woven …

Penetration in granite by shaped charge liners of various metals
… 2011 (T-3), aluminum 7075 (T-6), yellow brass, monel, maraging steel (vascomax 250), and copper was measured. Metals having high ductility and moderate compressive strength penetrated deeper than high strength maraging steel. Aluminum required a greater standoff for optimum penetration than the …

Effect of fabrication parameters on thermophysical properties of sintered wicks
… a loop heat pipe were sintered from copper and Monel powder. These wicks were characterized in terms of their shrinkage, porosity, thermal conductivity, liquid permeability and maximum capillary pressure. The effect of fabrication parameters (particle size and sintering conditions) on these …

Application of Optical Fiber Sensors for Quenching Temperature Measurement
… experiments performed on stainless steel, Monel k500, and Inconel 600 rods at atmospheric pressure, with different subcooling levels and surface roughnesses, will be discussed. The rewetting temperature measurement is performed to compare results between thermocouples and optical fiber …
