17-7PH stainless steel is high age-hardening property due to precipitate NiAl intermetallics by aging heat treatment after the deformation induced martensitic transformation by cold working. In this study, the effect of aging conditions on stress relaxation behavior of 17-7PH stainless steel was investigated, and the mechanism of the stress relaxation was discussed. The 0.2% proof stress after aging at 753K for 180s-18ks is about 450MPa, and then decreases after 18ks. On the other hand, the stress relaxation ratio decreases by long time aging at 753K. The dislocation density of 17-7PH decreases by long time aging at 753K. The formation of NiAl clusters around 5nm by 3D-AP analysis is observed in 17-7PH aged at 753K for 1.8ks. It is suggested that the reduction of the stress relaxation ratio after long time aging at 753K is caused by NiAl clusters and decreasing mobile dislocation density.

Rupture Behavior

Available equipment initially developed for welding research studies was used to investigate the creep-rupture behavior of AISI type 347 stainless steel in a very-high-temperature range from 62 to 86 percent of the solidus. Stress applications from 900 to 28,000 psi gave rupture times from a fraction of a second to several hundred seconds with thousandfold variations of minimum creep rate. Results could be presented by conventional means. Data scatter on a Monkman-Grant plot was typical. Correlation and extrapolation procedures developed by Larson-Miller, Manson-Haferd, Dorn, Korchynsky, and Conrad for conventional long-time results were found to be applicable, with preference being given to the Manson-Haferd procedures.

In this article discusses the mechanical properties of foam concrete, which submitted based on the experimental data of long force resistance and deformation of compression elements from foam concrete. Also submitted criterion range of strength and deformation characteristics of foam concrete different structural modification with taking into account the permanently acting load, which necessary for calculation and design structures of buildings. In article such characteristics of foam concrete as durability and deformability at the age of 28 days by results of short-term tests and also influence of average density and a type of structure on its durability and deformability are considered. Change of mechanical properties of foam concrete in time by results of short-term tests is analyzed and studied. Experimental and theoretical researches which have in turn allowed to recommend for rationing of value of settlement characteristics the foam of concrete taking into account their variability, aging and duration of action of loading are executed.

Using the model reaction of cumene oxidation the radical-forming ability of wear particles of some orthopaedic alloys and corundum ceramics were studied. It was revealed that wear particles from different alloys catalyzed cumene oxidation whereas particles of corundum ceramics were inert. Cobalt alloy wear particles were much more active as compared with the titanium alloy and stainless steel particles. Production of cobalt alloy by laser sintering reduced the radical-forming ability of its wear particles. Activity of cobalt wear particles was preserved for a long time after their formation and could considerably strengthen the development of oxidizing stress at joint arthroplasty. Detection of catalytic activity of orthopaedic alloys' wear particles requires studying of the influence of free radicals generated by tribochemical reaction upon implant components and biological tissues.
