    摘要: A method for designing multi-component high-strength titanium alloy, including the following steps: 1. smelting alloy ingots of specific compositions of the research system 2. cutting metal ingots into cubes of desired sizes; 3. preparing multi-component diffusion multiples. 4. performing vacuum-diffusion and annealing on the prepared diffusion multiples. 5. performing solution and aging treatments on the diffusion multiples after vacuum-diffusion and annealing. measuring the composition, microstructure and microhardness of different areas of the diffusion multiples, establishing the database of “composition-microstructure-hardness” correspondence of the titanium alloy. And 8. selecting a titanium alloy meeting design requirements in the titanium alloy database.

    摘要: A lens alignment system and method is disclosed. The disclosed system/method integrates one or more lens retaining members/tubes (LRM/LRT) and focal length spacers (FLS) each comprising a metallic material product (MMP) specifically manufactured to have a thermal expansion coefficient (TEC) in a predetermined range via selection of the individual MMP materials and an associated MMP manufacturing process providing for controlled TEC. This controlled LRM/LRT TEC enables a plurality of optical lenses (POL) fixed along a common optical axis (COA) by the LRM/LRT to maintain precise interspatial alignment characteristics that ensure consistent and/or controlled series focal length (SFL) within the POL to generate a thermally neutral optical system (TNOS). Integration of the POL using this LRM/LRT/FLS lens alignment system reduces the overall TNOS implementation cost, reduces the overall TNOS mass, reduces TNOS parts component count, and increases the reliability of the overall optical system.

    摘要: A method for manufacturing a golden member includes a first heating step and a second heating step. The first heating step is a step of heating, in the atmosphere of mixed gas including nitrogen gas and water vapor, a raw material member including titanium or a titanium alloy at 670° C. or higher and 730° C. or lower for 150 minutes or more and 200 minutes or less. The second heating step is a step of heating, in the atmosphere of nitrogen gas or in the atmosphere of mixed gas including nitrogen gas and inert gas, the raw material member passing through the first heating step at 670° C. or higher and 730° C. or lower for 30 minutes or more and 120 minutes or less so as to obtain a golden member including titanium or a titanium alloy.

    摘要: A method of producing medically applicable nanostructured titanium with improved mechanical properties includes performing an equal-channel angular pressing (ECAP) and subsequently performing a surface mechanical attrition treatment (SMAT). By performing the ECAP processing on a titanium sample, an ultrafine grained structure is obtained. The ultrafine grained structure may improve the biocompatibility and mechanical properties of pure titanium. When the SMAT processing is performed on the ultrafine grained structure, a nanostructured surface may be obtained. The SMAT processing may be used to enhance the strength of pure titanium to be used in medically applicable implants.

    摘要: A process to fabricate ultra-fine grain metal hollow object, comprising: inserting an annealed hollow prototype in an Equal Channel Angular Pressing (ECAP) die, providing a flexible elastic polyurethane mandrel to fill the central hollow space, optionally (if needed) provide polyurethane support to fill the spaces between the outer boundary of the prototype and the inner surface of the ECAP channel and to exert sufficient pressure to complete the ECAP process. The process is designed to improve thermal conductance and mechanical properties of hollow metal parts and is especially applicable to achieving the maximal heat conductance and tensile strength of titanium piping, construction tubing, and cylindrical reactors.
