State Of The Art Review On Selective Laser Melting Of Stainless Steel For Future Applications In The Marine Industry

Wenjin Wu, Shu Beng Tor, Kah Fai Leong, Chee Kai Chua et autres

This paper presents a state of the art review on the properties of stainless steel processed using Selective Laser Melting (SLM). SLM is an Additive Manufacturing (AM) process that uses laser to melt and fuse powder particles together to form 3-dimensional components. …

Investigation on processing of ASTM A131 Eh36 high tensile strength steel using selective laser melting

Wenjin Wu, Shu Beng Tor, Chee Kai Chua, Kah Fai Leong et autres

In this paper, selective laser melting (SLM) technique was used to investigate the processing of EH36 high tensile strength steel commonly used in the shipbuilding applications. EH36 powder was produced according to ASTM A131 standards using gas atomisation process. SLM process parameters, …

Errors in Marketing Strategies & Services of Middle & Small Private Enterprises

Xin Sun, Wenjin Wu

Net marketing is a new mar keting method. While there exist certain errors which have affected somewhat its development. We have to distinguish first of all those misunderstandings, then eliminate them for a better future development. Key words: middle & small enterprises, …

[A study on alpha-tricalcium phosphate bone cement carbon fiber-reinforced].

Wenjin Wu, Weizhong Yang, Dali Zhou, Jiang Ma et autres

In order to improve the mechanical properties of alpha-tricalcium phosphate (alpha-TCP), we prepared surface-modified carbon fibers (CF) reinforced alpha-TCP composite bone cement. Bone cement was soaked in Ringer's body solution to test its capacity of fast formation of hydroxyapatite crystals and self-solidification. …

Fatigue Crack Propagation in Polycarbonate

J. A. Manson, R. W. Hertzberg, S. L. KIM, Wenjin Wu

We investigated the effects of various material and fatigue parameters on crack-growth rate per cycle, da/dn, as a function of stress intensity factor range, ΔK. In contrast to other common polymers the frequency (0.1-20 Hz) or wave form has little effect on …

Structure of Polymers and Fatigue Crack Propagation

R. W. Hertzberg, J. A. Manson, Wenjin Wu

The fatigue crack propagation behavior of a very wide range of engineering plastics was examined. Crack growth rates per cycle were found to be a power function of the applied stress intensity factor range. In contrast to metals, the relative performance of …
