摘要： Provided is a production method with high productivity, which is not susceptible to the occurrence of cracks and thus has high yield when a sintered body of a thermoelectric conversion material is produced or when a sintered body for a thermoelectric conversion part of a predetermined size is cut out of a sintered body, and which is capable of cutting a plurality of sintered bodies for thermoelectric conversion parts out of one sintered body in cases where the sintered body is large in size. Also provided are: an Mg-Si system thermoelectric conversion material which exhibits stably high thermoelectric conversion performance; a sintered body for thermoelectric conversion, which uses this Mg-Si system thermoelectric conversion material; a thermoelectric conversion element having excellent durability; and a thermoelectric conversion module. A method for producing an Mg-Si system thermoelectric conversion material according to the present invention comprises a step for heating and melting a starting material composition that contains Mg, Si, Sb and Zn. It is preferable that the contents of Sb and Zn in the starting material composition are respectively 0.1-3.0 at% in terms of atomic weight ratio, and it is also preferable that the total content of elements other than Mg and Si is 0.2-5.0 at% in terms of atomic weight ratio.

摘要： A method of producing a master alloy for refining the grain size of a bulk alloy comprises the step of providing an Al—B alloy and adding Nb in elemental form to form an Al—Nb—B master alloy. The Al—B alloy may be prepared by providing an Al—B alloy with a higher boron content than is required and diluting it with elemental aluminium.

摘要： The invention relates to biodegradable, metal alloy-containing compositions, methods for their preparation and applications for their use. The compositions include magnesium and other components, such as yttrium, calcium, silver, cerium, and zirconium; or zinc, silver, cerium, and zirconium; or aluminum, zinc, calcium, manganese, silver, yttrium; or strontium, calcium, zinc. The compositions are prepared by vacuum induction/crucible melting together the components and casting the melted mixture in a preheated mild steel/copper mold. In certain embodiments, the compositions of the invention are particularly useful for forming medical devices for implantation into a body of a patient.

摘要： Polycrystalline compacts include a hard polycrystalline material comprising first and second regions. The first region comprises a first plurality of grains of hard material having a first average grain size, and a second plurality of grains of hard material having a second average grain size smaller than the first average grain size. The first region comprises catalyst material disposed in interstitial spaces between inter-bonded grains of hard material. Such interstitial spaces between grains of the hard material in the second region are at least substantially free of catalyst material. In some embodiments, the first region comprises a plurality of nanograins of the hard material. Cutting elements and earth-boring tools include such polycrystalline compacts. Methods of forming such polycrystalline compacts include removing catalyst material from interstitial spaces within a second region of a polycrystalline compact without entirely removing catalyst material from interstitial spaces within a first region of the compact.
