ALLOY

Incendiary weapons are known which generate intense heat and sparks by burning chemicals, such as thickened gasoline or phosphorus, or metals such as magnesium, aluminum, iron oxide powder (known as thermite), molten metal powder and zirconium. Such weapons are effective against targets that are flammable, such as wooden buildings and the like. However, they are limited in their destructive effect because they do not penetrate fuel tanks or armored vehicles, and because they consume themselves in a relatively short period of time, for example a minute or less. G

Alloys of rare earth metals have also been known for a long time. They are commonly used as flints for lighters because of their pyrophoric properties (that is, their ability to produce sparks when hit or hit by hard surfaces) and as additives in steelmaking to remove certain contaminants from the ice during the Remove peeling. So far they have been combined with silicon, aluminum, tin, zinc, nickel and iron in order to improve the hardness and the pyrophoric properties, and with copper in order to lower the melting point. Usually they have also been alloyed with about 2% magnesium to reduce oxidation and improve aging. However, such alloys were generally not used for the production of components because of their relatively low strength and because of their brittleness.

Rare earth metal alloys are also limited in their uses by the manufacturing processes available. The only commonly used procedure was that Single casting process »which is costly and time consuming. Some alloys got warm (for example at 218 to 257 C) and under high pressure (for example from 5040 to 9,100 kp / cm) pressed into flints and the like. Such alloys, however, have not yet been cold formed, cold drawn or drawn through Combination casting produced.

The invention overcomes these disadvantages and difficulties and provides a rare earth motallon alloy that is ductile and has good structural rigidity «as well a new method for hearing products »such as weapons.

In addition, the gosschosco, which contains the solid component, can be shotgun, as in shotgun cartridges , or simply compact or hollow rifle or artillery bullets. The bullets can be protected with a jacket made of metal, such as copper, for example The gecclunolr.ene metal is sprayed on or by simply dipping diocolbon "into the molten metal. In this way, damage to the barrel as a result of sparks and burning of the oil components as well as premature burning of the alloy during firing" and the It is preferred that not all parts of the bullet be encased. In particular, the nasal blocks should be left without a dumbbell, so that the pyrophoric and incendiary properties of the solid constituent components are fully effective at the moment the bullet hits the target is present

Rather, it fills to a powder which, according to the invention, can never be used. In some embodiments, a low degree of fluidity can be tolerated. The solid alloy component should preferably be tough, which should be somewhat ductile. For this reason, the magnesium content of the alloy should preferably be kept below 5% by weight.

The exact amount of rare earth metals, which form the main constituent of the solid constituent component, changes the design of the weapon. The preferred lower limit of the metals of the eeltenon ISrdon of the main constituent depends on the incendiary EicenDC adhesion of the solid alloy component being maintained. The pyrophoric properties were achieved with smaller honeys from the rare earths, such as only 8 % or 8 % mischmetal in an iron alloy (see Austrian patent specification 222.375).

The alloy component shows incendiary properties if, when heated to a limit temperature (for example 177 to 371 ° C) under atmospheric conditions (i.e. low in oxygen) a compact o piece weighing 1.5 pounds burns at temperatures for at least one minute, which are high gonuc to ignite usually flammable materials, such as wood and paper, which are in contact with them. The pre-combustion temperatures are preferably high, for example 1,093 to 1,650 ° C., and last a few minutes, sun example 20 to 25 minutes. The exact duration of the combustion depends on the size of the fragments of the decomposition component in which it is detonated weapon Een ~ is fragmented.

d) Alloys which contain 79 to 97% Micchmetall (purity 97 »5 %) and 3 to 25 % copper. During the trial, fragments of the gasoline alloys ignited in various weapons in the usual containers.

This is especially important when a strong explosive «» charge is used in combination with the alloy component to reduce the rate at which the alloy is consumed. In some embodiments, the alloy component therefore preferably contains a metallic composition as a smaller component part for the purpose of a controlled delay in the combustion speed of the alloy akoraponente.

Furthermore, the fragments have a sufficiently long burning time (for example 5 seconds) with high temperature and / or pyrophoric properties which ignite the combustible materials contained in such targets.

As already mentioned, in some designs the solid alloy component should be vorsugowoise from a lining :: -. exist part, which is arranged adjacent to a housing part. The lining part is preferably connected to the housing part. In this way, the fragments originating from Elnor V.'af fo were contained both parts of the legalization lcoinponcnto i and the housing part and in turn increased the penetrating and incendiary properties of the weapon.

believe it is necessary to share such a good bond which is not economically viable «On the other hand, increasing the temperature to less than 704 ° C is not expedient, because they are close to the melting point of the ο lining part (otwa 7UO ° C) approximates · With the specially made execution no it was found that heating to 650 to 677 ° C during 6 to 6 hours gives the best results

The intimate contact for the diffusion formation is achieved by cleaning surface parts of the cladding detail and the housing part and, in the meantime, bringing them into contact on those cleaned surface parts under pressure (for example by means of feet or weights). A ΑηηΙ ^ ο contact can also be achieved in that oborfläontoilo aea Ausklmeldungteils and the GohÜusotoils are cleaned and in which the alloy component is poured in contact with these cleaned wall parts in situ.

In the case of diffusion bonding, care should be taken to ensure that the alloy ion ponules which form the inner lining do not contain large amounts (for example 30 %) of the metal which was used to manufacture the metal part. Lei housing parts made of steel, for example, have been found that

a) if the alloy component contains 22.5% iron, a very poor bond is achieved, and

b) if the alloy component contains 12% Elsen, a good bond is achieved.

In this regard, pre-cuche were carried out in order to achieve the effect the change in the ratio of carbon to metal of the rare earths in the bathroom on the physical properties to determine the lodging.

Compact rods of 3.125 x 25 x 62.5 mm were gogooscn and then subjected to bending overouching. The bending tests were carried out by holding one end of the rod in a vice and striking the opposite end of the rod until the rod was either bent by 90 ° or broke off. In the present case, all rods were bent by 90 ° without breaking off. In addition, the bars had the same physical appearance. From this it was concluded that the ratio of mischmetal to carbon in the weld pool has no effect on the ductility of the loglorination. For further versions, a ratio of 90 % mischmetal to 10% graphite was chosen. . *

Additional bars were made using the ratio of 90 % mischmetal to 10 Ji graphite and subjected to chemical analysis. In each case, the bar was found to contain 0.06 to 0.08 % (± 0.005 %) carbon, compared to a maximum of 0.03 % (-0, OQJ '#) carbon for unalloyed mischmetal.

Attempts have also been made to determine the effect of the physical state of the carbon added to the schraolzo on the physical properties of the alloy.

The exact temperature and time period change in opposite directions. The temperature can be lower than 427 ° C, but a proportionally longer period of 48 hours is required to achieve good "annealing". Such extended periods of time are generally not economically viable. On the other hand, temperatures of more than 704 ° C are not twoclun ^ · Dig because they calibrate the melting temperature of the alloy (approx 760 ° C).
