...Yuki Nakamura; Shoichi Kikuchi; Tatsuo Sakai ABSTRACT To examine the effect of oxide layer thickness on fatigue behavior, rotating bending fatigue tests were performed on the aluminum alloy A2014-T6 with oxide layers of 3 different thicknesses in laboratory air and 3 % sodium chloride (NaCl...

...Yoshiyuki Furuya; Hideaki Nishikawa; Hisashi Hirukawa; Nobuo Nagashima; Etsuo Takeuchi ABSTRACT Fatigue data sheets of the National Institute for Materials Science disclose the results of gigacycle fatigue tests conducted on wrought aluminum alloys. The materials tested were hot-rolled plates...

...Osamu Umezawa To advance the understanding of metallic materials for structural components at cryogenic temperatures, a review of previous studies on the mechanical properties of austenitic stainless steels, titanium alloys, aluminum alloys, and copper alloys is presented herein. In particular...

...Mohammad Ammar Mofid; Mahmoud Farshbaf; Hamid Naeimian The transient liquid phase bonding of titanium and aluminum alloys was investigated, in which the interlayer was a 30-µm-thick brass foil and pure silver foil. The optimized variables used in this work are bonding temperature and time of 600°C...

...O. S. Sitdikov; E. V. Avtokratova; M. A. Murzinova; M. V. Markushev Evolution of the microstructure and microhardness of the cast and homogenized aluminum alloy 1570C (aluminum [Al]-5 magnesium [Mg]-0.18 manganese [Mn]-0.2 scandium [Sc]-0.08 zirconium [Zr], wt. %) were studied under...

...Addanki Ramaswamy; S. Malarvizhi; V. Balasubramanian The issues of dissolution or overaging of precipitates in the weld metal or heat-affected zone of aluminum alloy joints welded by conventional or constant-current gas metal arc welding (CC-GMAW) process are the key factors responsible...

...W. S. Mattos; G. E. Totten; L. C. F. Canale Uphill quenching is often not well understood and there are relatively few publications on the topic. Uphill quenching was originally developed by Alcoa approximately 50 years ago for aluminum alloys. It has also been referred to as “deep freezing...

... of silica-based coatings for corrosion protection of AA7075 aluminum alloy in saline environments rich in chloride ions. These coatings were obtained using the sol-gel technique. The samples were dip-coated in two types of solutions: (a) a mix of tetraethyl orthosilicate (TEOS) with 3-(Trimethoxysilyl...

...M. T. Milan; W. W. Bose, Filho; J. R. Tarpani Fatigue crack growth properties of friction stir welded joints of 2024-T3 aluminum alloy were studied via constant amplitude load (increasing Δ K ) testing under open air and accelerated salt fog exposure conditions. For low Δ K values, longitudinal...
