Rare earth magnet material and method for producing the same

Номер: US20120114515A1
Автор: Yuji Kaneko, Yukio Takada
Принадлежит: Toyota Central R&D Labs Inc

A method for producing a rare earth magnet material which allows efficient Dy or the like diffusion into an inside thereof. This method includes a preparation step of preparing a powder mixture of magnet powder including one or more rare earth elements including neodymium, boron, and the remainder being iron; and neodymium fluoride powder; a heating step of heating a compact of the powder mixture and causing oxygen around magnet powder particles to react with the fluoride powder, thereby obtaining a lump rare earth magnet material in which neodymium oxyfluoride is wholly distributed. The fluoride powder traps oxygen enclosed in the powder mixture and fixes the oxygen as stable NdOF. When Dy is diffused into this rare earth magnet material, Dy smoothly enters into its inside without being oxidized at grain boundaries. Consequently, coercivity of the entire rare earth magnet material can be efficiently increased without wasting scarce Dy.

A method of making aluminum nitride armor bodies is provided. The method starts with low cost bulk raw material, in the form of aluminum or aluminum alloy, cryogenically mills the raw material into a precursor powder, which is essentially free of oxides and other undesirable impurities. The precursor powder is formed into a pre-form using low cost, short residence time molding processes. Finally, the pre-form is exposed to a nitriding process to convert the pre-form into the aluminum nitride armor body. In this manner, the method avoids the use of high cost aluminum nitride as a starting material and avoids the need for the high cost, single axis densification processes of the prior art.

NOVEL METHOD OF IMPROVING THE MECHANICAL PROPERTIES OF POWDER METALLURGY PARTS BY GAS ALLOYING

Номер: US20140065003A1
Автор: Narasimhan Gopinath
Принадлежит:

The following specification describes a process for improving the hardness and other mechanical properties of iron and steel Powder Metallurgy (P/M) parts. The first stage of the novel process consists of heating to and holding at a temperature between 590° C. to 720° C. unalloyed or low alloyed P/M parts in an atmosphere containing a Nitrogen donor such as Ammonia in either batch or continuous furnaces. The concentration of ammonia during the first stage is maintained between 3% to 15%. The second stage of the inventive process is an ‘aging’ process which may be conducted either as an in-line process or as a stand-alone independent process that involves the heating of P/M parts that have fully or partially cooled after the first stage to a temperature between 180° C. and 660° C. in an atmosphere of plain air or Nitrogen. The first stage may be performed in varying concentrations of the nitrogen donor wherein the temperature and time duration may also be varied to control the depth of hardening in the said part. The conditions may be optimized to achieve through hardness of the part without embrittllement. The optional stage two of the technology is an aging process that does not involve “quenching,” thereby significantly lowering distortion of treated parts and eliminating pollution associated with liquid quenching. The technology improves process economy by using low temperatures and consequently fuel consumption. 1. A novel two stage process for heat treating unalloyed or low alloyed iron & steel P/M parts consisting of two major stages wherein the first stage is the alloying of the parts with Nitrogen gas which causes the formation of an austenitic phase in the metal matrix of the parts throughout the section thickness or to a controlled depth beneath the surface of the parts , in addition to the formation of hard transformation products and interstitial Nitrogen. This is followed in most but not all cases by a second stage of “aging” the P/M parts which causes ...

A variety of additive manufacturing techniques can be adapted to fabricate a substantially net shape object from a computerized model using materials that can be debound and sintered into a fully dense metallic part or the like. However, during sintering, the net shape will shrink as binder escapes and the base material fuses into a dense final part. If the foundation beneath the object does not shrink in a corresponding fashion, the resulting stresses throughout the object can lead to fracturing, warping, or other physical damage to the object resulting in a failed fabrication. To address this issue, a variety of techniques are disclosed for substrates and build plates that contract in a manner complementary to the object during debinding and sintering. 1. A method comprising:fabricating a support structure including a substrate for an object from a support material having at least one of a debind shrinkage rate and a sintering shrinkage rate matching a build material; andfabricating an object from the build material on the support structure, wherein the object has a net shape based on a computerized model, wherein the build material includes a powdered material for forming a final part and a binder system including one or more binders, wherein the one or more binders resist deformation of the object during a fabrication, a debinding, and a sintering of the object into the final part, and wherein the support structure is configured to match a shrinkage of the object during at least one of the debinding and the sintering.2. The method of further comprising fabricating the support structure on a build plate formed of a material that is debindable and sinterable.3. The method of wherein fabricating the support structure includes fabricating a build plate for use as the support structure by injection molding the build plate with the support material.4.
