metallurgically การใช้

• Copper alloys are much more robust metallurgically and naturally plentiful in their environment.
• Metallurgically the concentrate is likely to be relatively complex.
• However, it is difficult to treat metallurgically and remains a refractory ore type.
• The filler metal reacts metallurgically with the workpiece ( s ) and solidifies in the capillary, forming a strong joint.
• Beijing has made it clear that it wants foreign expertise to develop only low-grade or " metallurgically difficult " ores.
• "The beads, typically 100 祄 in diameter, are highly elastic, leave no residue, and produce a metallurgically clean surface without abrasion.
• Most grades of steel are melted once and are then cast or teemed into a solid form prior to extensive forging or rolling to a metallurgically sound form.
• There was a 150-year period in which better and more metallurgically advanced steel armor was being used, precisely because of the danger posed by the gun.
• The coating on 2017 sheet-and later on 2024-T3-consisted of commercial-purity aluminum metallurgically bonded to one or both surfaces of the sheet.
• Saipem now uses either zirconium stripper tubes, or bimetallic tubes with a titanium body ( cheaper but less erosion-resistant ) and a metallurgically bonded internal zirconium lining.
• In the . 408 CheyTac cartridge casing design particular attention was directed toward thickening and metallurgically strengthening the case's web and sidewall immediately forward to the web to accommodate high chamber pressures.
• A : The " golden " dollar is a three-layer composite clad coin, with a pure copper core sandwiched between _ and metallurgically bonded to _ the outer layers of alloy material.
• Indeed, the correct crystal structure can only be obtained when the 5f states are included, proving that thorium, and not protactinium, acts as the first actinide metallurgically with the clear influence of the 5f orbitals.
• Ever since Wittle and others introduced jet engines for aircraft, jet engine design engineers have specifically calculated on the basis of using fuel thermal capacity to keep " parts " of an engine at temperatures low enough metallurgically.
• This was an alumino-thermic process in which a powder'portion'was ignited; the aluminium was the fuel and a metallurgically appropriate composition of molten steel descended into the gap between the rail ends, contained in refractory moulds.
• A subset of the standard DTIs described above, is the " squirter " type DTI that contains a small amount of material in the cavity of each protrusion . " Squirter " type DTIs are mechanically and metallurgically identical to the standard DTIs described above, except as the protrusions of squirter type DTIs collapse upon tightening, the cavity material is expelled to the outer diameter of the device indicating protrusion compression, i . e . bolt tension, visually.
