Ductile Sentence Examples

Sudden cooling makes the metal extremely ductile, and slow cooling makes it brittle.

It is a silver-white ductile metal (of specific gravity 2.54) which melts at 8000.

According to Chenevix, the alloy composed of equal parts of the two metals is grey, is less ductile than its constituent metals and has the specific gravity i i.

There are many metals and alloys which are malleable and ductile, and also readily fused and cast.

For ductile iron or mild steel it may be taken as 1.5.

By the application of a pointed iron hook, while the glass is still ductile, the parallel coils can be distorted into bends, loops or zigzags.

Broadly the malleable and ductile metals and alloys show a fibrous character when ruptured, the fusible ones a crystalline fracture.

According to some authorities, pure zinc always yields ductile ingots.

In view of the fact that the presence of 1% of carbon implies that 15% of the soft ductile ferrite is replaced by the glass-hard cementite, it is not surprising that even a little carbon influences the properties of the metal so profoundly.

Thus, though sudden cooling has very little effect on steel of o io% of carbon, it changes that of 1.50% from a somewhat ductile body to one harder and more brittle than glass.

This is only possible with malleable and ductile metals and alloys.

The remaining solder bump is then almost pure lead, creating a very ductile column.

Hence tin and lead, though very malleable, are little ductile.

Gold and Zinc.-When present in small quantities zinc renders gold TABLE II.-Gold brittle, but it may be added to gold in larger quantities without destroying the ductility of the precious metal; Peligot proved that a triple alloy of gold, copper and zinc, which contains 5.8% of the lastnamed, is perfectly ductile.

The alloy of 4 parts of gold and i part of palladium is white, hard and ductile.

It is malleable and ductile.

The important manganese steels of commerce and certain nickel steels are manganiferous and niccoliferous austenite, unmagnetic and hard but ductile.

Manganese steel and nickel steel form an important exception to this rule, in being at once very strong and hard and extremely ductile.

It is a greyish white metal, and is very malleable and ductile.

It is a white metal of bluish tint and is malleable and ductile.

The material retains the nodular graphite distribution of ductile iron, but the matrix is acicular ferrite in a high carbon austenite.

Fcc metals, however, generally remain ductile at low temperatures.

Zinc becomes more ductile at temperatures above room temperature.

The use of the technique in the study of fatigue crack initiation and growth in ductile cast irons will also be given.

By 1970 the material had become commercially available and today well over half of all iron castings produced worldwide are made in ductile iron.

The problem was in casting ductile steel into ingots without creating air pockets, which made the metal unsound.

It is the third most malleable and sixth most ductile metal, yielding sheets 0.000025 in.

It is the common, very magnetic form of iron, in itself ductile but relatively soft and weak, as we know it in wrought iron and mild or low-carbon steel.

It is the most tenacious of all the ductile metals at ordinary temperatures with the exception of cobalt and nickel; it becomes brittle, however, at the temperature of liquid air.

When diluted down to 4.8%, it assumes the colour and fusibility of bronze, but, unlike it, is tenacious and ductile like iron.

The pure metal is silver-white in colour, is very ductile, and becomes remarkably hard when hammered, a diamond drill making little impression upon it.

It is extremely magnetic and almost non-magnetic; as brittle as glass and almost as pliable and ductile as copper; extremely springy, and springless and dead; wonderfully strong, and 1 The word " iron " was in 0.

Thanks to the glass-hardness of this face, the projectile is arrested so abruptly that it is shattered, and its energy is delivered piecemeal by its fragments; but as the face is integrally united with the unhardened, ductile and slightly yielding interior and back, the plate, even if it is locally bent backwards somewhat by the blow, neither cracks nor flakes.

The ductile metals and alloys also extend from Jo to 30 with reduction of area before they fracture, the crystalline ones snap shortly without warning.

If zinc be cast into a mould at a red heat, the ingot produced is laminar and brittle; if cast at just the fusing-point, it is granular and sufficiently ductile to be rolled into sheet at the ordinary temperature.

Second, though the brittleness should be lessened somewhat by the decrease in the extent to which the continuity of the strong matrix is broken up by the graphite skeleton, yet this effect is outweighed greatly by that of the rapid substitution in the matrix of the brittle cementite for the' very ductile copper-like ferrite, so that the brittleness increases continuously (RS), from that of the very grey graphitic cast irons, which, like that of soapstone, is so slight that the metal can endure severe shock and even indentation without breaking, to that of the pure white cast iron which is about as brittle as porcelain.

It takes a brilliant polish, is in a high degree malleable and ductile, and in tenacity it only falls short of iron, exceeding in that quality both silver and gold.

It is also extremely ductile; a single grain may be drawn into a wire 500 ft.

It is bad taste to imitate the tracery of the ductile wrought iron in cast designs, the foliations of ancient wrought-iron grilles and screens in heavy cast iron.
