The Increase Of Cavitation Erosion Resistance Of Stainless Steel Products By Carbon Supersaturation

Published: 2014
Authors: Andreas Karl, Martina Wagner

While the excellent corrosion resistance of austenitic and duplex stainless steels has resulted in wide commercial application of these materials, poor tribological behaviour, especially low abrasive / adhesive wear resistance and a tendency to fretting, has prevented the use of these materials in applications where both corrosion and wear resistance are required.

High Bonding Strength Between Stainless Steel And Aluminum Alloy Using Resistance Spot Welding

Published: 2014
Authors: Chihiro Matsuda, Kyyou Yun, Junghyun Kong, Shunji Yanase, Masahiro Okumiya, Ibrahim bin Ishak, Toshifumi Kakiuchi and Yoshihiko Uematsu

Recently, a transportation machine such as automobiles has been become indispensable in our lives. A great amount of energy is required to use the transportation machine. Reduction of the weight is one method of improving fuel efficiency of the automobiles.

Investigation On The Plasmon Enhanced Light Localization In Photovoltaics And Optical Sensing

Published: 2014
Authors: Tong Zhang, Guang Qian, Jing -Yuan Wu, Sheng-Qing Zhu, Jie Tang, Xiao-SuXu, and Xiao -Dan Ma

Localized surface plasmon resonance of linked plasmonic nanostructures (LPN s) leading to strong light field enhancement at hot spots gains great attractions in nanophotonics. We showed the progress in the engineering of the optical spectra of the LPNs by controlling their shape and space distribution, and investigate their application in thin-film optical devices.

Sintering Behavior of Components Produced By Additive Manufacturing Using Gas Versus Water Atomized 420 Stainless Steel Powders

Published: 2014
Authors: Y Zhou, S.C. Siw, M. Orange, C. Schade, and C.I. Garcia

The fabrication of components using gas atomized and water atomized starting powder materials via Additive Manufacturing was employed to study and compare their sintering behavior. The approximated initial powder average size was very similar ( 2 5 ^ m ) for both powders.

Object Dependent Properties Of Multi-Component Acrylic Systems

Published: 2014
Authors: Ian V. Kidd, Elan J. Weiss, Laura S. Bruckman, Olivier Rosseler, Roger H. French

Optical and chemical properties are used to track degradation of hardcoat acrylic systems with PET and TPU substrates. Magnitude and variance of yellowness is correlated to UV irradiance, 0.92 and haze is correlated to moisture in UV irradiance, 0.84, in PET substrate candidates.

Cavitation Erosion Resistance Of Active Screen-Low Temperature Plasma Nitrided Aisi 410 Martensitic Stainless Steel

Published: 2014
Authors: L .A . Espitia, Hanshan Dong, Xia o-Ying L i, C.E. Pinedo, A.P. Tschiptschin

AISI 410 martensitic stainless steel specimens were low temperature plasma nitrided at 400┬░C in a mixture of 75%N2:25%H2, during 20 h. Active screen technic was used to avoid any edge effect.

Austenite Evolution During Limited Roughing Of Htpsteel

Published: 2014
Authors: Kevin Banks and Rorisang Maubane

The evolution of austenite during and immediately after roughing has been investigated with the aim of achieving a fine, uniform grain size in thick high temperature processing (HTP) steel skelp. Four-pass rolling simulations were performed after which austenite softening and the extent of grain refinement were determined from flow curve analysis and metallography respectively.

Effect Of Nickel Additions On Solidification Structure And Aging Response In Copper-Manganese Alloys

Published: 2014
Authors: Kevin J. Chaput and Kevin P. Trumble

Recently a binary alloy based around the congruent point (Cu-35Mn) in the Cu-Mn system was developed as a lead-free casting bronze. The unique feature of this alloy was that the as-cast microstructure displayed a cellular solidification structure free of shrinkage porosity.

Flow And Temperature Field Evolution During Solidification Of An Electromagnetically Stirred Melt: Influence Of Magnetic Shields

Published: 2014
Authors: Gregory Poole, Laurentiu Nastac

This paper investigates the effect of magnetic shield placement in proximity to an electromagnetically-stirred melt undergoing solidification. The electromagnetic field in both the molten metal and magnetic shields was computed using the mutual inductance technique. An improved dual-zone model was employed to describe the flow behavior in the mushy region.

Hydrogen Storage Properties Of Nanostructured Calcium Nitride

Published: 2014
Authors: Hayao Imamura, Naotaka Shimomura, Sota Nagamine, Maiko Shimizu and Yoshihisa Sakata

Nanostructured and active calcium nitride (Ca2N) with high surface areas of 113 m2 /g was prepared when calcium amide (Ca(NH2 )2 ) obtained by the reaction of Ca metals with liquid ammonia was thermally decomposed above 923 K. Ca2N thus obtained showed the hydrogen uptake capacity under mild conditions.
