摘要： A method of refining a microstructure of a titanium material can include providing a solid titanium material at a temperature below about 400° C. The titanium material can be heated under a hydrogen-containing atmosphere to a hydrogen charging temperature that is above a β transus temperature of the titanium material and below a melting temperature of the titanium material, and held at this temperature for a time sufficient to convert the titanium material to a substantially homogeneous β phase. The titanium material can be cooled under the hydrogen-containing atmosphere to a phase transformation temperature below the β transus temperature and above about 400° C., and held for a time to produce a phase regions. The titanium material can also be held under a substantially hydrogen-free atmosphere or vacuum at a dehydrogenation temperature below the β transus temperature and above the δ phase decomposition temperature to remove hydrogen from the titanium material.

摘要： An antimicrobial and adhesion-proof titanium tableware and a manufacturing method of the same are provided. The antimicrobial and adhesion-proof titanium tableware is made of a titanium substrate, and includes a contact portion and an oxidation layer structure. The contact portion is used for contacting foods, food ingredients, drinking water, beverages, or body parts of a user. The oxidation layer structure is formed on one part of a surface of the titanium substrate corresponding to the contact portion. The titanium substrate is made of titanium in α phase, and the oxidation layer structure is a titanium dioxide film in a rutile crystalline form. The oxidation layer structure has a roughened surface and an oxygen diffusion layer formed at an interface of the oxidation layer structure and the titanium substrate.

摘要： A thermally stabilized fastener system and method is disclosed. The disclosed system/method integrates a fastener (FAS) incorporating a faster retention head (FRH), fastener retention body (FRB), and fastener retention tip (FRT) to couple a mechanical member stack (MMS) in a thermally stabilized fashion using a fastener retention receiver (FRR). The MMS includes a temperature compensating member (TCM), a first retention member (FRM), and an optional second retention member (SRM). The TCM is constructed using a tailored thermal expansion coefficient (TTC) that permits the TCM to compensate for the thermal expansion characteristics of the FAS, FRM, and SRM such that the force applied by the FRH and FRR portions of the FAS to the MMS is tailored to a specific temperature force profile (TFP) over changes in MMS/FAS temperature. The TCM may be selected with a TTC to achieve a uniform TFP over changes in MMS/FAS temperature.
